Why monitor dust?

17/04/2018
Josh Thomas of Ashtead Technology discusses the reasons for monitoring dust in the workplace.

Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the implementation of an effective risk management strategy.

There are two major reasons for monitoring dust in the workplace; to enable air quality management, and for regulatory compliance. The immediate effects of dust can be irritation to eyes, headaches, fatigue, coughing and sneezing. As such, poor indoor air quality can lower employee performance and cause increased absenteeism through sickness. In addition, particulates are known to create long-term deleterious effects, contributing to serious illnesses. In combination with outdoor exposure (to pollution form vehicles for example), the Government has estimated that 29,000 premature deaths occur in the UK every year as a result of particle pollution. This means that, particularly in urban areas, natural ventilation may not necessarily improve indoor air quality.

Dust-TrakEmployers are responsible for ensuring that staff and visitors are not exposed to poor air quality in the workplace, so it is necessary to conduct monitoring. Accurate and effective monitoring data can be used to check exposure levels and to help identify safe working practices.

Monitoring also helps to demonstrate compliance with relevant regulations. COSHH is the law that requires employers to control substances that are hazardous to health. According to the Health & Safety Executive (HSE), employers can prevent or reduce workers’ exposure to hazardous substances by finding out what the health hazards are; by deciding how to prevent harm to health; by providing effective control measures; by providing information and training; by providing monitoring and health surveillance, and by planning for emergencies.

In order to evaluate workplace safety, monitoring data is compared with Workplace Exposure levels (WELs) which prescribe the maximum exposure level to a hazardous substance over a set period of time. Failure to comply with COSHH and WELs can result in financial penalties, prosecutions and civil claims.

Indoor air quality is affected by both internal and external factors. Air pollution may arise from external sources such as neighbouring factories, building and development activities, or from vehicles – especially those with diesel engines. Internally, air quality is affected by working practices and business processes. For example, dust may arise from raw materials such as powders, or it may be produced by processes that generate particulates; including dust, mist, aerosols and smoke. In all cases, internal and external, it is important to identify both the source and the seriousness of the problem, so that appropriate and effective mitigation measures can be implemented. These might include, for example, ventilation, process dust prevention, the management of shift patterns, personal protection equipment (PPE) and alarm systems.

Regulatory requirements to monitor
Under the British Workplace (Health Safety and Welfare) Regulations 1992, employers have a legal duty to ensure, so far as is reasonably practicable, the health, safety and welfare of employees. Furthermore, the Management of Health and Safety at Work Regulations 1999 (GB) require employers to assess and control risks to protect their employees. A key element of this is the requirement to comply with the COSHH Regulations. The HSE says that exposure measurement is required:

  • For COSHH assessment, to help select the right controls
  • Where there is a serious risk to health from inhalation
  • To check that exposure limits are not exceeded
  • To check the performance of exposure controls
  • To help select the right respiratory protection equipment
  • To check exposure following a change in a process
  • To show any need for health surveillance; or
  • When an inspector issues an ‘Improvement Notice’ requiring monitoring

The COSSH Regulations include dust, mist, vapour, fumes and chemicals, but they do not cover Lead or Asbestos. Specific requirements exist for certain industries such as construction. Generally, WELs relate to particulate diameter because the health effects of particulates are heavily influenced by their size.

Inhalable dust is that which enters the nose or mouth during breathing and is available for deposition in the respiratory tract. It includes particles with a width between 2.5 and 10 microns (PM2.5 – PM10), and the WEL for this fraction is 10 mg/m3 as an 8-hour Time Weighted Average (TWA).

Respirable dust is the fraction that penetrates deep into the gas exchange region of the lungs. It includes particles with a width between 1 and 2.5 microns (PM1– PM2.5), and the WEL for this fraction is 4 mg/m3 as an 8-hour TWA. Lower specific WELs exist for particulates that present a greater threat to health. For example, Silica dusts have a WEL of just 0.1 mg/m3 respirable dust as an 8-hour TWA.

The costs of non-compliance
In addition to the enormous numbers of premature deaths that result from exposure to outdoor air pollution, there are also numerous well-documented instances demonstrating the harm caused by exposure to indoor pollution from dust, smoke, aerosols and vapour. For example, a 46-year-old cook developed breathing problems after working with flour in a school kitchen with poor ventilation. Her breathing problems became so severe that she could hardly walk and had to sleep sitting up. She became severely asthmatic and had to retire early on health grounds. With the support of her Union she made a compensation claim on the basis that decent working conditions were not provided, and the council admitted that it had not taken sufficient action despite repeated complaints. Consequently, the courts awarded the cook £200,000 (€230k) in damages.

In another example, between 1995 and 2004, a solderer was exposed to rosin based solder fumes and suffered health deterioration and breathing problems including asthma. An investigation conducted by the HSE found that the company did not have adequate control measures in place and failed to install fume extraction equipment. Furthermore, the company did not employ rosin-free solder until December 2003, despite an assessment having identified the need in 1999. The company was subsequently fined £100,000 (€116k) with £30,000 (€35k) costs, a punishment which attracted both local and national media attention.

Monitoring dust
A wide variety of methods exist for the measurement of dust, and the choice of equipment is dictated by the application. For example, it is obviously important to employ a technology that is able to measure the particulates that will be present. In addition, it will be necessary to determine whether monitoring should be continuous, at a single point, or whether portable instruments are necessary to check multiple locations. Monitoring might be conducted in a work space, or personal sampling might be undertaken in order to assess the exposure of an individual over an entire shift.

Personal Sampling Pumps represent the preferred method for workplace exposure monitoring where it is necessary to demonstrate regulatory compliance or where legal dispute is a possibility. An HSE document (MDHS 14/4) provides workplace exposure monitoring guidance for collecting respirable, thoracic and inhalable aerosol fractions. The samples collected by this process are analysed in a laboratory, which means that chemical analysis is also possible. However, the sampling method incurs a delay and incurs extra cost.

In response to the wide variety of applications and monitoring requirements, Ashtead Technology stocks a comprehensive range of monitors for both sale and rental, providing customers with complete financial and technical flexibility. As a TSI Gold Partner, Ashtead Technology provides a comprehensive range of maintenance and calibration services; helping customers to ensure that their monitoring equipment remains in optimal condition. Ashtead’s fleet of rental equipment includes large numbers of the latest TSI instruments, supported by the highest levels of service and technical assistance. Employing advanced light-scattering laser photometers, the TSI products are supplied with a calibration certificate and provide real-time, direct-reading aerosol monitoring and analysis of different particulate fractions in workplace, cleanroom, HVAC, fugitive emissions and environmental monitoring applications.

The TSI range of dust monitors is continually being developed to bring new levels of functionality to the market. For example, the new lightweight AM520 Personal Dust Monitor is able to measure and log PM10, Respirable (PM4), PM5 (China Respirable), PM2.5, PM1 or 0.8μm Diesel Particulate Matter (DPM), providing real-time audible and visual alarms, and running from a rechargeable battery for up to 20 hours. For outdoor applications, the MCERTS approved Environmental DustTrak is web-enabled, providing a quick and easy dust monitoring solution for applications such as building and development projects.

Methane detection in mines.

21/03/2018

Mining is big business, with the world’s 50 largest mining companies worth a total of 1 trillion dollars (€0.81 trillion). Worldwide, the mining industry is responsible for the direct employment of 3.7 million people, with over 150 million indirectly supported by small-scale mining operations.  Many other sectors, such as high-tech industry, are also entirely dependent on mined supplies of materials.

Guardian NG detects methane

There is inherent danger in creating and operating within subterranean tunnels which results in a high mining date rate, over 5 deaths per day due to mining accidents recorded in China alone. This is a worldwide problem, with high-profile incidents in the last 10 years occurring in New Zealand, Russia and the US among others.

The most common source of mining accidents, particularly in coals mines, is an explosion of methane gas. Methane is a colourless, odourless gas which is trapped in mines as part of the coal formation process. As coal is formed from compressed plant matter methane is produced as a by-product then, when rocks are excavated, methane is released into the local atmosphere with potential deadly consequences.

Methane Explosions in Mines
Methane explosions in mines are the result of the concentration of a methane leak in a closed environment. If methane reaches a critical concentration in the air, which is between 5 to 15 % it can react with the oxygen to form carbon dioxide, water and heat. This reaction needs a source of ignition to begin. This doesn’t necessarily have to be an open flame, sparks from mining processes, or a high localised temperature (over 600 °C) on hot equipment, can be enough to cause an explosion.

The pressure wave created by a methane explosion is often more dangerous than the initial explosion. The waves can displace large amounts of coal dust, spreading highly flammable particles throughout the air. The dust can ignite as part of a chain reaction, spreading flames along the mining shaft, consuming any available oxygen to further fuel the fire and generating large amounts of toxic gases.

Safety Measures to Avoid Methane Explosions
Methane release is unavoidable in coal mines as it is always present. The problem with methane explosions is not just restricted to active mining sites either. Many abandoned also leak methane gas, potentially into residential areas where it can still reach high enough concentrations to be at risk of explosion.

The risk of methane gas accumulation in mines means that gas sensing is an essential part of any mining safety network. To reduce the risk of methane build up, ventilation equipment is used in mines to keep methane concentrations below the explosion limit.

Sensors can be placed at ventilation exits to mine, measuring the outgassing of methane to determine that the methane concentration in the mine itself is not close to critical methods. External sensors are also important to monitor the release of methane to the environment surrounding the mine.

In order for gas sensing to be an effective safety measure, the gas sensors used must be able to detect low methane concentrations at a high reliability.

The Guardian NG for Methane Detection
One sensor range that is suited to the critical safety issue of detecting methane outgassed from mines is the Guardian NG series from Edinburgh Sensors. Capable of detecting methane concentrations between 0-1%, these infra-red based sensors are sensitive enough to detect even the smallest of leaks.

The Guardian NG series is designed as an easy-to-use, standalone gas sensor that can continually monitor and log methane concentrations in conditions where the gas is present between 0 – 100 % volume, with the most sensitive sensor being able to detect between 0-1%. The sensor has an impressively rapid 1.5 minute warm-up time and is capable of operating in a range of conditions varying from 0 – 95 % relative humidity and 0 – 45 °C.

What makes the Guardian NG series particularly well-suited to mining applications is they can be easily integrated in to existing ventilation equipment. As the sensor itself is electronic and could generate sparks, it should be situated on the surface of the mine measuring gas concentrations released from the mine vents. This provides a guarantee that ventilation systems are working and can also be used to monitoring the off-gassing of old mining sites.

Infra-red sensors offer some advantages over the traditional heat of combustion sensors that are typically used for mining applications and are commonly used in other areas where methane detection is required as methane absorbs infra-red light very strongly at characteristic wavelengths. They also offer faster response times and potentially have longer service lives than heat of combustion sensor alternatives.

One huge advantage of IR sensors in safety applications is the fail-safe nature of the technology. If the IR lamp, and therefore the sensor, fails then no signal is received by the detector, which is an equivalent effect to the sensor detecting a high methane concentration. As a result, a full alarm would sound, notifying staff that the sensor has failed and there is a potentially dangerous situation.

With its sensitivity and accuracy for methane detection and short response time of less than 30 seconds from sample injection, the Guardian NG series offers one answer to the critical safety issue of explosion prevention in mining.

Train derailment prompts contaminated land investigation.

11/01/2018

A train derailment in Mississippi resulted in ground contamination by large quantities of hazardous chemicals, and environmental investigators have deployed sophisticated on-site analytical technology to determine the extent of the problem and to help formulate an effective remediation strategy. Here Jim Cornish from Gasmet Technologies discusses this investigation.

Jim Cornish

On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi (USA). At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency response and initial remediation activities were undertaken, but the remainder of this article will describe an environmental investigation that was subsequently conducted by Hazclean Environmental Consultants using a portable multiparameter FTIR gas analyzer from Gasmet Technologies.

Background
Over 17,000 gallons of Resin Oil Heavies were released from the railcar, and the main constituent of this material is dicyclopentadiene (DCPD). However, in addition to DCPD, Resin Oil Heavies also contains a cocktail of other hydrocarbons including ethylbenzene, indene, naphthalene, alpha-methyl styrene, styrene, vinyl toluene, 1, 2, 3-trimenthylbenzene, 1, 2, 4-trimethylbenzene, 1, 3, 5-trimethylbenzene and xylenes.

DCPD is highly flammable and harmful if swallowed and by inhalation. Its camphor-like odor may induce headaches and symptoms of nausea, and as a liquid or vapor, DCPD can be irritating to the eyes, skin, nose, throat or respiratory system. DCPD is not listed as a carcinogen, however DCPD products may contain benzene, which is listed as a human carcinogen. DCPD is not inherently biodegradable, and is toxic to aquatic organisms with the potential to bioaccumulate.

It is a colorless, waxy, flammable solid or liquid, used in many products, ranging from high quality optical lenses through to flame retardants for plastics and hot melt adhesives. As a chemical intermediate it is used in insecticides, as a hardener and dryer in linseed and soybean oil, and in the production of elastomers, metallocenes, resins, varnishes, and paints. DCPD-containing products are also used in the production of hydrocarbon resins and unsaturated polyester resins.

Emergency Response
Emergency response phase activities were performed from March 31 through May 2, 2015. Response objectives and goals were formally documented by utilizing Incident Action Plans for each operational period. Activities between April 11 and April 28, 2015 were summarized in weekly reports and submitted to the Mississippi Department of Environmental Quality (MDEQ) and the Environmental Protection Agency (EPA).

Approximately 10,189 gallons of the leaked product was recovered, leaving 5,458 gallons to contaminate the farmland surface and subsurface soil, surface waters, groundwater and ambient air. The site contamination problem was exacerbated due to heavy rainfall and associated stormwater runoff which caused the unrecovered product to migrate from the spill site.

Taking account of the high rainfalls levels that followed the event, it was calculated that contaminated stormwater runoff from the immediate project site (10 acres with 8.7 inches of rainfall) was 2,362,485 gallons less that retained by emergency retention berms. Approximately 207,000 gallons of contaminated stormwater were collected during the emergency response, in addition to approximately 7,870 tons of impacted material which were excavated for disposal. Following removal of the gross impacted material, the site was transferred into Operation and Maintenance status, conducted in accordance with a plan approved by MDEQ.

Ongoing site contamination
Groundwater and soil samples were collected and analyzed in 2015 and 2016, producing analytical data which confirmed that widespread soil and groundwater contamination still existed at the site. Further remediation was undertaken, but the landowners were extremely concerned about the fate of residual chemicals and contracted Hazclean Environmental Consultants to conduct a further investigation.

“The affected land is used for agricultural purposes, producing crops such as soybeans and corn,” says Hazclean President, E. Corbin McGriff, Ph.D., P.E. “Consequently, there were fears that agricultural productivity would be adversely affected and that chemicals of concern might enter the food chain.
“This situation was exacerbated by the fact that the landowners could still smell the contamination and initial investigation with PID gas detectors indicated the presence of volatile organic compounds (VOCs).”

Hazclean’s Joseph Drapala, CIH, managed and conducted much of the site investigation work. He says: “While PID gas detectors are useful indicators of organic gases, they do not offer the opportunity to quantify or speciate different compounds, so we spoke with Jeremy Sheppard, the local representative of Gasmet Technologies, a manufacturer of portable FTIR (Fourier Transform Infrared) gas analyzers.

Soil Vapor Analysis with FTIR

“Jeremy explained the capabilities of a portable, battery-powered version of the Gasmet FTIR gas analyzer, the DX4040, which is able to analyze up to 25 gases simultaneously, producing both qualitative and quantitative measurements. Gasmet was therefore contacted to determine whether this instrument would be suitable for the Mississippi train spill application.

“In response, Gasmet confirmed that the DX4040 would be capable of measuring the target species and offered to create a specific calibration so that these compounds could be analyzed simultaneously on-site.”

Site investigation with FTIR analysis
A sampling zone was defined to capture potential contamination, and measurements were taken for surface and subsurface soil, groundwater, and surface and subsurface air for a range of VOCs.

Vapor Well

The area-wide plan resulted in the installation of four permanent monitoring wells for groundwater sampling, twenty vapor monitoring wells, and twenty test borings for field screening. The test borings indicated the presence of VOCs which were further characterized by sampling specific soil sections extracted from the parent core.

In addition to the almost instantaneous, simultaneous measurement of the target compounds, the Gasmet DX4040 stores sample spectra, so that post-measurement analyses can be undertaken on a PC running Gasmet’s Calcmet™ Pro software, providing analytical capability from a library of 250 compounds. “The Gasmet DX4040 was manufacturer-calibrated for dicyclopentadiene, benzene, ethylbenzene, naphthalene, styrene, toluene, 1,2,3-trimenthylbenzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene and m, o, and p and total xylenes at a detection range of 0.01 ppm to 100 ppm in air,” Joseph reports, adding: “The ability to compare recorded spectra with the Calcmet Pro library is a major advantage because it enables the measurement of unknown compounds.”

The operating procedures for the DX4040 indicate a simple, convenient requirement for daily calibration with zero gas prior to each monitoring activity. However, in addition to the use of nitrogen as the zero gas, Joseph also employed specialty gas (DCPD) certified for 1 ppm and 5 ppm as a calibration check and a response (akin to bump testing) gas.

Site screening
The test borings provided soil samples that were vapor-tested on-site as part of the screening process. Vapor from the extracted soil samples was analyzed by placing the soil samples in vessels at ambient temperature and connecting the DX4040 in a closed loop from the vessel, so that air samples could be continually pumped from the vessel to the analyzer and returned to the vessel. This screening activity helped to determine the location for vapor wells.

All soil samples were screened with the DX4040 and those with the highest reading from each boring were sent for laboratory analysis.

Vapor wells were fitted with slotted PVC liners and capped. Before monitoring, the cap was replaced with a cap containing two ports to enable the DX4040 to be connected in a similar closed-loop monitoring system to that which was employed for the soil samples.

Conclusions
As a result of this investigation it was possible for Hazclean to determine that the release of DCPD in the vapor state, as measured in the vapor monitor wells, is a result of surface and subsurface contamination in the soil and groundwater, and that this contamination will remain in the future.

Vapor analysis data provided by the DX4040 identified DCPD, benzene, styrene and xylene previously adsorbed on soil and/or wetted surfaces undergoing diffusion and evaporation. The adsorption, diffusion and evaporation of DCPD et al. released and spread across the farmland is a mechanism to explain the vapor concentrations found in vapor monitor wells as well as the ambient malodor problem.

The long term release of DCPD and other VOCs will continue to occur in the impact area unless a larger remediation project is conducted to remove soil and groundwater contamination. Furthermore, Hazclean recommends that, as a result of the effectiveness of the Gasmet DX4040 in this investigation, the same technology should be employed in any subsequent screening activities, using the same Gasmet calibration configuration.

Summarizing, Joseph Drapala says: “The Gasmet DX4040 was an essential tool in this investigation. Screening activities should have the ability to detect and identify the target compounds, as well as any secondary compounds that may have already been present on-site or could have been produced as a result of chemical interactions.
“As an FTIR gas analyzer, the DX4040 meets these requirements, providing enormous analytical capability through Gasmet’s Calcmet software. However, the instrument is also small, lightweight and battery powered which makes it ideal for field investigations.”


#EmrEX: All change at Brussell Centraal.

18/04/2016
Emerson User Group EMEA in Brussels, Belgium – 12th – 14th April 2016

“Seems to me that #EMrex is focusing not so much on new technologies, though important, but looking closer at how we do things.”  our tweet on day one.
Cfrpq9-UUAE8qVi

Brussels looked lovely on the morning that the Emerson User Group meeting opened. There was little to suggest the trauma that the city had faced just a few short weeks previously as delegates strolled through the sun-lit streets to the conference centre. The security however was markedly tighter as we entered the building however with strict adherence to the best security practices. However once inside the building things were as normal.

 Emerson Exchange Brussels – The Videos!

Other Reports (as they appear)
• Operational Excellence at Emerson Exchange Brussels (Emerson’s Stuart Turner – 20/4/2016).
• Nick Denbow ‘s travel travails: My worst week as an air traveller!  (30/4/2016)

Speaking with the organisers it promised to be a bumper event, stretched as it was over three days examining all aspects of automation, experiences, applications and of course exciting new products and concepts. The attendance was slightly down on the last time in Stuttgart, some were reluctant to travel, others were unable to make it due to the inability of the severely damaged to adhere to a normal service. Those who attended were in part in broad agreement with the message penned by Emerson’s Travis Hesketh – Standing up for Brussels. Indeed the User Group very quickly confirmed after these terrible events that they were going ahead with #EMrex. At several of the social events at the periphery, like the evening reception for publishers and journalists the people who suffered were remembered.

The venue was a modern conference and the one hundred or so presentations and industry forums were stretched over about six floors including an exhibition floor and at the very top of the building was a cyber café and a wonderful panoramic hall with the breathtaking view (featured at the top of this page from a tweet by Emerson’s social media guru – Jim Cahill)

But on to the the meeting!

Peter Iles-Smith of GlaxoSmithKline opened proceedings as chair of the Users Exchange Board. He welcomed the over two thousand delegates from so many countries through out the EMEA who travelled for the event.

Steve_SonnenbergSteve Sonnenberg, President Emerson Process Management (pictured right) and Roel VanDoren, their President in Europe, in a joint presentation entitled “New Reality, New Opportunity” addressed the changes and challenges facing companies in the 21st Century. They did not talk about products or applications but on ways of doing things. Indeed during the presentation we tweeted: “Emerson’s approach – yes equipment, but more importantly perhaps is attitude or culture.”

Nobody does business the way they it was done even twenty years ago, when the internet was a baby and nobody imagined never mind thought possible social media platforms like twitter,  yet in many cases industry is way behind in adapting to change. Possibilities are there which were inconceivable a short time ago and these need to be harnessed for the good of humanity.

Research into these possibilities, new technologies are leading to changes especially the importance of planning including all stakeholders at the earliest opportunity. This thinking is leading to an innovative technology and engineering-based approach for improved capital efficiency such as their Project Certainty approach  which aims to tackle complexity by decoupling the dependencies suppliers have on each other, eliminating bottlenecks and allowing concurrent work streams. In a word it aims to transform capital investment and releasing the frightening amounts of money currently being lost in big and not so big projects.

And these figures are frightening. If the type of approach spoken of here is adopted savings of up to €400 Billion (yes BILLION) would be released to invest in, for instance,  production, reliability, safety, energy, training, security and innovation.

So what is involved?

Xavier_MarchantXavier Marchant, (right), Emerson’s Vice President Process Systems and Solutions in Europe, gave dramatic examples of the possible savings in labour and materials. For instance the decision to use smart junction boxes in a large project could save both money and space (95% in control room space). Spare parts are another area where there is phenomenal waste. He quoted a spokesman from a International Energy and Chemical Company, “On our last construction project we overspent on maintenance spares to the tune of €50,000,000…we just wrote it off….because we did not have a robust spares analysis process.” Reduce the complexity by the involvement of stake holders at the start of planning for a project and allowing them to develop it side by side. One simple idea is to separate software from hardware in the development. The “old way” is to tie them together from the start whereas this way the software can be developed using virtual systems and then later on when the actual operation is seen to work in the virtual world (he called it virtual FAT – Factory Acceptance Test) it may be introduced to the real or concrete world – or “late binding” as he called it.

vFAT
Virtual FAT has far less chance of harming one than the real thing?

He quoted  François Davin of Sanofi “Emerson’s Remote Virtual Office allowed us to collaborate with experts and resources from multiple sites to conduct our Factory Acceptance Test (FAT). The result was less travel and site disturbance to our operations. Also, more operators could participate remotely which improved the new automation system adoption.”

We were introduced to the concept of  quartile performance and their site Top Quartile Performance is a exposé of how they view this as a concept and how it is influencing their thinking as a group.

Peter_Zornio

Of course all these changes would be impossible without the availability and enthusiastic embracing of the so-called “new” technologies. Peter Zornio (right), Emerson’s irrepressible Chief Strategic Officer, gave us an insight into these and how the company is using these and its co-operative involvement with the pioneers in these , the Internet of Everything(CISCO),  Industrial Internet (GE), Smart Planet (IBM) and The Internet of Things (Microsoft). These technologies, and others embryonic or not even conceived of are guiding  the current and future development of technology used in the manufacturing and processing sectors.

Keynotes: The Emerson User Exchanges whether in the USA or EMEA always have exciting and inspirational keynote speakers each day. This event was no exception. Jack Uldrich, a futurist spoke about future-proofing business. The majority of businesses are not ready for what is happening in the real world or for the speed at which it is happening.

Another of these speakers Prof Jan Rotmans who spoke about change. He maintains that we are not living through an “era of change” as a “change of era!” Many of us are in the old era, our mobile phone is just that, we read newspapers, buy books in bookshops. Our kids live on their mobile phones, they are their liveline. We are “old-fashioned” our kids are “cool!” Change is disruptive and the old ways are totally unable to cope. The old top-down certainties are dissolving and the “common man” is taking charge, sometimes violently. Chaos is the name of the game.

Finally a veteran at EmrEX, David Beckman, brought all the thoughts and ideas of New Reality, New Opportunity together. In view of Rotmans’ talk earlier the title he chose was more than relevant as he introduced delegates to the “Worst Case Scenario Survival Handbook.” Although he prepared us for worst case scenarios he described real opportunities for industrial automation.

Presentations. The various threads were divided into five headings or sectors, Business & Projects; Operate Safely, Securely and Legally; Process Optimisation; Maintenance & Reliabilitym and, Control System Applications & Migrations and were held through each of the days.

Forums: There were also Industry Forums with panels and general discussions on the various specialities e.g. Life Sciences or Refining & Petrochemicals. These were opportunities for participants to learn and exchange information and experiences with each other.

Training: There were also training  sessions and other sessions (called Roadmaps) on Emerson products and possible future developments.

projcertExpo

ExpoEmrEx16274Solutions EXPO: Of course no event is complete without actually seeing product and EmrEX is no exception. The floor was divided under the same zone headings as the threads of presentations above. (See sketch on left).

There were several unique exhibits. One was the Operations Centre of the Future. This was an imaginative presentation of a plant with a H.A.L. like computer responding (or not) to commands or requests from the operatives. It featured a drone delivery of spare parts and a really effective alarm situation which featured a realistic vibration of the floor. Of course the real message is that though it is the future most of the technology used is possible today.

Of course the Project Certainty concept featured prominently in the Business & Projects area and we were show possible scenarios. They had also rather bravely set up a wall where delegates could post what they consider are the features that should be addressed in projects. This should help “to focus ruthlessly on what’s directly relevent to a company strategy.”

Of course there were actual instruments on display to examine and handle.

Ind1stNotable was this industry first, the Rosemount X-well system, a wireless transmitter, accurately measuring process temperature without need for thermowell. Accurate process temperature measurement is possible without requiring any intrusions or penetrations into the process, allowing for quicker and easier installation along with simplified long-term maintenance. Users do not have to design, size or maintain thermowells. Wake Frequency Calculations are eliminated, as well as time spent determining material compatibility, the right insertion length and the necessary profile.

pressure_gaugeAlso the new Emerson Wireless Pressure Gauge created quite buzz among delgates. Th“This new gauge design fundamentally will change how customers use pressure gauges by helping them make better business decisions!”  It is another industry first. Does this signal the end of the Bourdon Tube?

Energy management is of course critical in all processes. It is effected not only by cost factors but also by legislation driven by concerns on pollution and global warming. Here Emerson demonstrated some prototypes of monitoring and control equipment not yet available. They emphasised savings on space occupied and of course ease of use by operatives.

Jim_CahillAnother very popular item was on the Maintenance & Reliability Zone. Here was an opportunity to experience the immersive training simulator. A goggle like apparatus was placed on the head and using a game-like hand piece the engineer is able to travel through a plant and see where various problems may be without any danger to him or her. It is a fascinating experience and one really feels that one is travelling through the plant rather than sitting or standing in a control room or office.  In this picture we see Emerson’s Chief Blogger, Surface Dweller, Head of Social Media enter the virtual world for real! We can confirm that he returned to real reality afterwards.

Around the periphery of the EXPO were the booths of companies which compliment the Emerson offering – what they call their complementary and strategic partners.

history-passageThere was also a section dedicated to history featuring milestones in science and automation over the years. It was a demonstration of change in the past. What will feature in future shows? The new opportunities taking advantage of the new realities of the past.

Always a major highlight of the Emerson User Group events is waht the call the “Networking Event.” This year was rather unique in that it was a visit to the Museum of Fine Arts and the Magritte Museum. This was an unique opportunity to see the best of Belgian painters – creativity of a different type than that extolled during the day sessions. Artists such as the Brueghels, Rubens, Jordaens and Magritte were enjoyed during this evening. Food and beverages were served – Belgium is famous for its beers of course but it also has its own cuisine and of course it’s chocolate is to die for.

This years event, despite the unexpected difficulties, was on a par, indeed because of these difficulties had perhaps more user participation than previous ones. There were many exciting things to see, concepts to understands and friends with which to share experiences.  And of course fun with a capital F.

Look at this and tell me people weren’t enjoying themselves! (Twitter pic ‏@Julian_Annison)

Food & Pharmaceutical Futures.

21/03/2016

ISA’s first international symposium outside of North America is adjudged a success.

centreview

From the time it was firsted mooted for Ireland in 2015 the planning for the 3rd ISA Food & Pharmaceutical Symposium was embraced with enthusiasm by the local Ireland Section. This was in Philadelphia early in 2015  and since then the ISA’s Food & Pharma Division under the able directorship of Canadian Andre Michel has ploughed forward overcoming setbacks and the not inconsiderable distances between North America and the capital of Munster. Chair of the symposium and former Ireland Section President, Dave O’Brien directed a strong committee charged with ensuring the this, the first such international symposium organised by the ISA outside of North America would be a resounding success.

And it was.

Venues were assessed, speakers recruited and the various minutiae associated with organising an international event were discussed, duties asigned and problems solved over many late night transatlantic telephone conferences. Using the experience of the ISA staff in North Carolina and the many years experience of organising table-top events and conferences in Ireland by the Ireland Section a very creditable event was staged at the Rochestown Park Hotel. With some justification the Symposium Chair could state before the event started “We have assembled a truly outstanding program this year, featuring some of the world’s most accomplished experts in serialization, process optimization, cyber security and alarm management to name a few. These experts will speak on the vital issues affecting food and drug manufacturers and distributors. We are delighted to have the opportunity to bring this event to Ireland for its first time outside of the United States!” Indeed upwards of 200 registrands attended the two day event and it was notable that the bulk of these stayed until the final sessions were completed.

• All through the event highlights were tweeted (and retweeted on the Ireland Section’s own twitter account) with the hashtag #FPID16. See also the ISA official release after the event: Food & Pharma symposium almost doubles in size!

Technology and Innovation for 2020 Global Demands
Two fluent keynote speakers, Paul McKenzie, Senior Vice President, Global Biologics Manufacturing & Technical Operations at Biogen (who addressed “Driving Change Thru Innovation & Standards”) and Dr Peter Martin, VP and Edison Master, Schneider Electric Company (Innovation and a Future Perspective on Automation and Control) may be said to have set the tone. The event was also graced with the presence of ISA Internationa President for 2016 Mr Jim Keaveney.

We will highlight a few of the sessions here!

Serialization:
The important subject of serialization which affects all level of the pharmaceutical business especially in view of deadlines in the USA and the EU. From an overview of the need and the technology to a deep dive into the user requirements, this session provided the latest information on the world requirements and helping provide the solution needed in each facility. Speakers, as in most sessions, were drawn from standard, vendor and user organisations as well as state enforcement agencies.

Track & Trace:
In the parallel Food thread of the symposium the role of track and trace technologies were examined. Product safety, output quality, variability and uniqueness of customer requirements manufacturers are facing increasing demands on the traceability of raw materials, real-time status of manufactured goods and tracking genealogy of products throughout the value chain from single line to the multiple sites of global manufacturers. The evolution of data systems and technologies being offered means greater benefits for Industry and presenters Vision ID and Crest will show these solutions and the advantage of modernization.

 

day1a2Both threads came together for much of the event mirroring the similarity of many of the technologies and requirements of each sector.

Digitalization:
Digitalization in industry shows what bringing the worlds of automation and digitalization together provides true and advanced paperless manufacturing with more complex devices and interconnected data systems. This is an enabler to integrated operations within industry. Using MES as a core concept to create a Digital Plant and optimized solutions with data driven services was explained. And a practicale example of a plant was discussed showing the journey to paperless manufacturing and a real pharmaceutical strategy of integrating automated and manual operations.

Cybersecurity:
Of course this is one of the key topics in automation in this day and age. Without implementing the proper preventative measures, an industrial cyber-attack can contribute to equipment failure, production loss or regulatory violations, with possible negative impacts on the environment or public welfare. Incidents of attacks on these critical network infrastructure and control systems highlight vulnerabilities in the essential infrastructure of society, such as the smart grid, which may become more of a focus for cybercriminals in the future. As well as threats from external sources steps ought to be taken to protect control and automation systems from internal threats which can cripple a company for days or months. This session highlighted the nature of these threats, how systems and infrastructure can be protected, and methods to minimize attacks on businesses.

 

Automation Challenges for a Greenfield Biotech Facility:
These were outlined in this session in the pharmaceutical thread. Recent advances in biotechnology are helping prepare for society’s most pressing challenges. As a result, the biotech industry has seen extensive growth and considerable investment over the last number of years. Automation of Biotech plants has become increasingly important and is seen as a key differentiator for modern biotech facilities. Repeatable, data rich and reliable operations are an expectation in bringing products to market faster, monitor and predict performance and ensure right first time delivery. This session provided the most topical trends in automation of biotech facilities and demonstrated how current best practices make the difference and deliver greater value to businesses.

Process Optimization and Rationalization:
Meanwhile in the Food & Beverage thread incremental automation improvement keeps competitiveness strong. Corporate control system standardization leads to constant demand for increases in production and quality.

Industry 4.0 (Digital Factory: Automate to Survive):

Networking

Networking between sessions

The fourth industrial revolution is happening! This session asked how Global Industry and Ireland are positioned. What did this mean to Manufacturer’s and Industry as a whole? The use of data-driven technologies, the Internet of things (IoT) and Cyber-Physical Systems all integrate intelligently in a modern manufacturing facility. Enterprise Ireland and the IDA headlined this topic along with the ICMR (Irish Centre for Manufacturing Research) and vendors Rockwell and Siemens.

OEE and Automation Lifecycle: Plant lifecycle and Operational Equipment Effectiveness

More networking

Worldwide today many of the over 60 Billion Euro spend in installed control systems are reaching the end of their useful life. However, some of these controls, operational since the 80’s and 90’s, invested significantly in developing their intellectual property and much of what was good then is still good now. Of course some aspects still need to evolve with the times. This requires funding, time and talent. For quite some time now there has been a skilled automation shortage at many companies leading organizations to outsourcing, partnerships and collaboration with SME’s to help manage the institutional knowledge of their installed control systems. With corporate leadership sensitive to return to shareholders, plant renovation approval hurdle rates are usually high when it comes to refreshing these control systems. In many manufacturing facilities, engineers and production managers have been asked to cut costs and yet still advance productivity. To solve this dilemma, many world class facilities continue to focus on driving improvements through the use of automation and information technology. Some are finding that using existing assets in conjunction with focused enhancement efforts can take advantage of both worlds. Here we were shown great examples of where innovation and such experiences are helping to create real value for automatio modernization.

Alarm management:
And of course no matter how sophisticated systems are Alarms are always require and neccessary. DCSs, SCADA systems, PLCs, or Safety Systems use alarms. Ineffective alarm management systems are contributing factors to many major process accidents and so this was an importan session to end the symposium.

The social aspect of this event was not forgotton and following a wine reception there was a evening of networking with music at the end of the first day.

Training Courses:
On the Wednesday, although the symposium itself was finished there were two formal all day training courses. These covered, Introduction to Industrial Automation Security and the ANSI/ISA-62443 Standards (IC32C – Leader Eric Cosman, OIT Concepts ), and Introduction to the Management of Alarm Systems (IC39C – Leader Nick Sands, DuP0nt). These, and other, ISA courses are regularly held in North America and the Ireland Section occasionally arranges for them in Ireland.

All in all the Ireland Section and its members may feel very proud in looking back on a very well organised and informative event which in an email from one of the attendees, “Thank you all, It was the best symposium I attended in the last 10 years!”

Well done!

It’s the little things that trip you up!

22/01/2016
By Brian Booth, VP of the Water Treatment Innovation Platform, NCH Europe

There’s a lot of chemistry, physics and maths involved in perfecting your water treatment solution. To make sure you successfully treat and protect your system you need to get the equilibrium right, and this relies on balancing all the appropriate equations – even the little things you may not give much thought to. Missing something like half life out of your planning can have serious negative implications for your water treatment, especially when it comes to complying with regulations such as those for Legionella control.

When dosing your water cooling system with biocides it’s imperative that the concentration is correct and that it remains at a continuous concentration for a suitable period of time. While this sounds simple, it’s easy to forget that any bleed water required to compensate for water that may evaporate out of a system, will take a portion of your biocide with it.

Say you put 10 tonnes of make-up water into your system, and every hour 1 tonne runs off as bleed water, this will determine the half life for your system. So for example, let’s imagine the chemical you are using to meet the Government’s Health and Safety Executive (HSE) Legionella control L8 Code of Practice needs to remain at a concentration of 100 parts per million (ppm) for three hours to be successful.

If you just dose 100ppm and walk away, the concentration will gradually fall from the time of dosing and will not remain high enough for long enough as the bleed water will take a portion away with it. This will result in a failure to meet the regulation, making you negligent and leaving you liable.

This is why it’s vital to be aware of half life so that you can increase the dose of your biocide accordingly. Do you know how many hours it would take to reduce a 100ppm dose to 50ppm in your water cooling system?

Although it’s hard to be 100 per cent accurate, you can work out your half life with this simple equation:

 

Half_Life_hours.jpg

If you know your biocide is going to take three hours to be effective, but the half life of your system is one hour you’re going to have to make some adjustments to maintain appropriate concentration. For instance, using our above example of legionella control biocide, to stay at a minimum of 100ppm for long enough you’ll need to dose to 800ppm.

A bit of predictive mathematics goes a long way towards protecting your water system and keeping you compliant. Don’t let a little thing like half life leave you vulnerable to negligence claims – do the maths first!

A new (3-D) perspective in presence detection.

06/04/2015
Irish/German co-operation in new technologies creating a paradigm shift in the planning of safety for current and future manufacturing systems.

Presence detection is a critical element in the basis of safety for many pharmaceutical and bio pharmaceutical processes. Detecting presence of workers prior to start-up and during operation of machinery and processes is an effective means of injury prevention. Likewise product can be protected from human contamination using collaborative robots allied with relevant 3-D presence detection. The pharmaceutical sector has always had to deploy sophisticated processes and technology in its manufacturing environment while maintaining the highest safety standards.

G-Funktionsprinzip-SafetyEYE-EN-568This is an approach which responds positively to the need for worker safety while minimising production disruption. Process components such as centrifuges and barrel mixers pose a significant risk to workers because of high speed rotational action or agitation. Likewise transportation of storage units such as intermediate bulk containers and the use of automated wrapping and palletising machinery create the need for effective safeguarding. 3D sensing systems provide many advantages through the introduction of barrier-free safeguarding.

SafetyEYE, a 3-D virtual detection system, provides a comprehensive protection zone around such machinery. Developed jointly by the Pilz Software Research and Development team in Cork (IRL) and the Product Development division in Ostfildern (D), the company considers SafetyEYE as an example of new technologies creating a paradigm shift in the planning of safety for current and future manufacturing systems.

Named ‘Safety Company of the Year’ for 2014 by the Institution of Occupational Safety and Health’s (IOSH) Desmond-South Munster Branch, the award recognised Pilz’s commitment to continuous innovation, singling out the development of SafetyEYE as central to this commitment.

Bob Seward, chair of the IOSH Desmond-South Munster Branch, said: “The development of this innovative SafetyEYE technology will make a significant difference in terms of protecting people at work while they operate around machinery danger zones. Our members were very impressed with SafetyEYE and what it can achieve in terms of accident prevention and safeguarding workers.”

The world’s first 3D zone monitoring system SafetyEYE comprises a three-camera sensing device, an analysis unit and programmable control capability.

The sensing unit creates the image data of the zone to be protected and the stereoscopic cameras allow for precise distance and depth perception. Adjusting the height of the camera device allows for varying zone dimensions and areas of coverage. The image data is processed by the analysis unit to detect any intrusion of the defined 3-D protection zone and is relayed to the programmable safety and control system (PSS) for activation of the appropriate safety response.

The avoidance of an obstacle-course of physical guards has obvious advantages for increased freedom of interaction and ergonomics between machinery and humans without compromising safety for both. Because of the highly configurable software a wide range of detection zones can be designed either using pre-defined geometric forms or bespoke shapes. These zones can then be assigned various safety-related actuations with reference to the risk from an audio-visual warning to shut-down.

SafetyEYE can be used to prevent start-up of machinery when persons are in a danger zone or provide warnings and if necessary activate a shutdown if an operator enters a danger zone while such plant is running. The system can be configured to signal a warning as the worker enters the perimeter of the defined safety zone and as he continues further into the zone initiate further safety actions. The machine can remain in this suspended state while the worker completes his task. Once the worker has cleared the area the machine’s activities can resume in accordance with the worker’s egress from the safety zone. This incremental reactive capability allows for minimum downtime and so optimal productivity is maintained. For workers who only encroach on the outer points of the safety zone the triggered warning will uphold the safety integrity of the work space without limiting operation. Likewise, the system can be configured to allow for pre-defined spaces within the protection zone to be breached without shut down. This is especially useful for supervisory personnel who need to access control components which lie within the safety zone. Again they may complete their task safely without the need to disrupt the manufacturing process.

To achieve the same level of safety in such a scenario as this, a whole range of other safety measures may have to be deployed, such as guard-doors, with the physical and visual restrictions these solutions will impose. Safety for workers venturing beyond these guards would then require optical sensors which operate two-dimensionally along a plane and may require a multiplicity of sensors to provide comprehensive monitoring. This mix of solutions can present significant cost implications and their static single-plane positioning will raise costly design challenges. As SafetyEYE is positioned above the manufacturing area it does not present any physical or visual obstruction and it is also far less likely to be interfered with than other ground-level safety measures which are always more vulnerable to intentional or accidental interference. The 3-D zonal capability means that one sensor unit can provide far more safety coverage than the planar sensors. Such imaging-based devices also have a recording functionality so that safety zone breaches can be recorded or production activity monitored to feed into productivity metrics.

These attributes were acknowledged by Bob Seward of the IOSH when presenting Pilz with the award. “With the introduction of this certified technology, safety can no longer be seen as a barrier to work, slowing work down or stopping work. It can be truly integrated in the work system.”

Pilz Ireland managing director John McAuliffe said: “Pilz were honoured to receive this award. The area of safety in which we work is constantly changing and Pilz need to be innovative in order to provide our customers with solutions that achieve safety in lean manufacturing environments.” Providing services from risk assessment, safety design and safety training to customers all over the world the company views continuous development of processes and products, such as SafetyEYE, as vital in meeting the constantly evolving demands of the modern manufacturing environment.

The Association for Packaging and Processing Technologies (PMMI) estimates that 34% of primary pharmaceutical operations in North America by 2018 will be carried out by robots, compared with 21% in 2013. This increasing automation, along with the rapid growth of collaborative robots across all sectors, is heralding a new era of human-robot interaction in manufacturing.

SafetyEYE is especially effective in ensuring the safe deployment of collaborative robots which are ideal for handling materials and ingredients in a decontaminated environment but which require some level of interaction with operators who need to approach to carry out supervisory, control or intervention tasks.

Such are the potential production efficiencies brought about by collaborative robotics in the bulk pharmaceutical manufacturing sector that Health and Safety managers, engineers and suppliers will need to align their safety strategy in line with this new industrial environment.

As with all new technologies care and due process must be exercised in the integration with other plant and machinery. Structured risk assessment considering the specific hazards leading to intelligent safety concepts are the key to successful adoption of such new technologies. Pilz is pioneering safe automation with the continuous development of its services and products, such as SafetyEYE, ensuring that its customers can anticipate the safety challenges presented by industry developments such as collaborative robots.
