EEMUA has released Edition 4 of EEMUA 191, Alarm systems – A guide to design, management and procurement.

Since it was first published in 1999, EEMUA 191 has become the globally accepted and leading guide to good practice for all aspects of alarm systems.

The new edition has been comprehensively updated and restructured to improve ease of use. The terminology has been aligned to that used in the latest editions of the standards and the opportunity has been taken to include new material on alarm management for remote sites.

Alarm systems form an essential part of the operator interfaces to large modern industrial facilities. They provide vital support to the operators by warning them of situations that need their attention and have an important role in preventing, controlling and mitigating the effects of abnormal situations.

EEMUA 191, developed by the users of alarm systems in industry, gives comprehensive guidance on designing, managing and procuring an effective alarm system. It is intended to help in improving existing systems and in developing new facilities during plant construction or during alarm system refurbishments. Both of the international standards for the management of alarm systems for the process industries, ISA 18.2 and IEC 62682: 2023, are aligned with EEMUA 191.

EEMUA 191 is primarily concerned with alarm systems provided for people operating industrial processes. These include alarm systems in industries such as chemical manufacture, power generation, oil and gas extraction and refining and others. However, much of the guidance is generic and with appropriate interpretation can be applied in other sectors. The guide has been used successfully as a basis for training in the rail and transport sectors, in the nuclear industry, and elsewhere.

i.safe MOBILE sets new standards with its new 5G radio IS440.1

In recent years, there has been an increasing shift from conventional radio technology to digital PMR technology, particularly in the industrial sector. This is where private 5G mobile networks come into play, meeting growing connectivity needs with higher coverage, bandwidth and security. Reliable communication is essential for team coordination on large company sites - in hazardous and non-hazardous areas. As not all parts of the company are usually converted to digital formats immediately, a cross-technology solution for group communication is required.

i.safe MOBILE responds to the demands of industrial users

The new development from i.safe MOBILE closes this gap: The 5G radio provides secure and interference-free PoC communication via public or private 4G/5G networks on site or Wi-Fi® as a backup connectivity. The ATEX/IECEx certified 5G radio IS440.1 for Ex-zone 1/21 enables seamless group communication via a PoC bridge server with existing devices like two-way radios (TETRA, DMR and analogue PMR). The new 5G radio supports 3GPP Release 15 and has a very reliable chipset on board. The device features a user-oriented look and feel, a replaceable battery (with 2400 or 4800 mAh), large keys for PTT, SOS, talk group selection, dual SIM (with automatic network switching), a powerful front speaker (>105 dB) for noisy environments, a unique 8-pin ISM interface for connecting headphones and heavy duty headsets (HDHS) and a functional fixing clip.  

The 5G radio is mostly used in the campus network, but an alternative SIM card for the public network can of course also be inserted to have a fallback option in an emergency, another fallback option is of course the connection via Wi-Fi. In terms of connectivity, it is equipped with Wi-Fi 6, NFC (for access control, data transfer between two devices, reading NFC tags) and Bluetooth® 5.2. In addition to all major public 4G/5G frequency bands, the IS440.1 also supports the CBRS spectrum and B68 for public safety applications.

The user can download selected apps compatible with the device directly from the pre-installed i.safe MOBILE App World and update them regularly. The App World contains product-related, pretested push-to-talk and MDM solutions. With the corresponding app from App World, the IS440.1 is more than just a radio. The IS440.1 enables advanced functions such as:

• Push-to-Talk: instant communication at the touch of a button
• Full-duplex communication: Seamless two-way calls
• Video streaming: visual information exchange in real time
• Protection of lone workers: Increased safety for isolated workers

Robin Hartmann, Manager Operative Business Development of i.safe MOBILE comments: “With the development of our 5G radio, we are responding to many of our customers’ requests for a  bridge technology between existing communication devices such as two-way radios and modern 5G devices on the road to digital transformation. This gives customers the opportunity to gradually digitalize their communications.”

Dr. Leszek Kasprzak, Principal Risk & Safety Consultant, and Dr. Shirin Pegg, Technical Director at Bureau Veritas, discuss how Fault Tree Analysis is helping to re-evaluate risk, and what this means for the future of Dangerous Substances and Explosive Atmospheres (DSEAR) assessment.

The modern-day approach to risk assessment must keep pace with technological advancements and emerging hazards. Forward-thinking methodologies are redefining the boundaries of safety and reliability within evaluation of hazardous facilities.

One of the most recent and innovative developments in risk assessment practices is the comprehensive application of Fault Tree Analysis (FTA). Unlike more traditional assessment models, FTA offers a detailed, system-level approach to identifying potential failure paths and evaluating the risk of critical events. This method allows organisations to gain a deeper, data-driven understanding of complex risk factors. Such insights not only support compliance but actively enhance safety measures and operational efficiency.

FTA and its significance in the current landscape

The answer to this lies in the multi-layered nature of modern industrial processes, where a single fault can trigger cascading failures. FTA maps out intricate dependencies and quantifies the likelihood of such chain reactions, considering elements like human error, component failures, and environmental influences. For instance, when analysing the risk of hydrogen explosion at battery charging stations potentially leading to severe injuries, the assessment shows transparently the presence of potential ignition sources, process controls and ventilation system failure; and occupancy level within the impacted area. This level of transparency is crucial for mitigating risks comprehensively and proactively.

Modernising risk assessment reports is another essential aspect of evolving safety practices. Detailed visual representations and extensive data references, sourced from reputable industry statistics and authoritative agencies, enhance comprehension, translating complex assessments into actionable insights. When reports are designed with clarity and precision, they not only inform but foster trust through well-documented methodologies and findings.

A significant challenge faced by many industries today is the risk posed by emerging technologies, particularly lithium-ion batteries. The multi-faceted hazards associated with these energy storage solutions are only beginning to be fully understood. Risk assessments need to extend beyond standard flammable risk considerations to include factors such as thermal runaway reactions, which can be influenced by environmental and operational variables. By examining oxidizers and reactive chemical interactions, risk evaluations can highlight potential failure scenarios that might otherwise be overlooked. Such forward-thinking analysis is essential for addressing next-generation industrial challenges.

The ability to anticipate and evaluate evolving risks - from hydrogen use in new energy systems to advanced battery technologies - positions risk assessment not just as a regulatory requirement but as a strategic pillar for safety innovation. Continuous refinement of methodologies ensures that organisations are not only compliant but prepared for the unexpected.

In an era where safety cannot be compromised, meticulous and forward-thinking risk assessments set a benchmark for resilience. Expertise and a commitment to proactive strategy are necessary to initiate a conversation that challenges the industry to think beyond immediate risks and toward future-proofed safety.

Early detection of explosions and fires

 With the GSME and HOTSPOT detectors from REMBE, an artificial intelligence has been created that detects fire and explosion events at an early stage. The GSME detector is an artificial nose, "trained" for pyrolysis - popularly known as smoldering gases, while the HOTSPOT detector represents an artificial eye that already detects surface temperature changes of 1 °C.

REMBE´s HOTSPOT X20 measures surface temperatures using an intelligent evaluation system, which divides the field of view into detection zones. A separate temperature threshold value can be set for each individual zone in order to tailor the detection to the process as far as possible. The HOTSPOT X20 can even identify small temperature increases (1 °C) and enables to warn the operator of a fire or glowing embers at extremely early stages. The HOTSPOT X20 can also be used in explosion atmosphere up to zone 20 and under high dust loads and monitors a temperature range in the standard version of 0-200 °C (higher temperatures possible, but typically not required).

Temperature monitoring can be particularly helpful when handling secondary fuels. Where gas measurement technology becomes very complex due to cross-sensitivities, temperature is a simple parameter for detecting process anomalies. Common mounting points are above or on conveyors so that the process flows can be monitored. If elevated temperatures are detected, the potential ignition source can be stopped before it reaches the next potentially explosive atmosphere.

Mainly hydrocarbon compounds are released when many substances thermally decompose. If there is incomplete burning without a flame and a low oxygen supply, carbon monoxide is created as well. The GSME X20 pyrolysis gas detector, for instance, has been designed for detecting these gases, even as they develop. Alongside carbon monoxide and hydrocarbon compounds, nitrogen oxide and hydrogen compounds (CO, HC, H2 and NOx) are also monitored. With the aid of an intelligent evaluation algorithm, a process behaviour can be ideally mapped and normal off-gasing be adopted. If a concentration increases above the usual level, the GSME X20 immediately triggers an alarm. The detector, is also suitable for explosion atmospheres up to zone 20, monitors concentration ranges from 0-100ppm.

Gas measurement technology can also be used for traditional energy sources. However, this must be suitable for the harsh environments. Thanks to the multi-component measurement, the GSME detector can also be used in storage facilities.

When the location and mounting position are ideally designed in an explosion protection concept, HOTSPOT X20 and GSME X20 allow explosions and fires to be prevented through early detection.

 In this article we will dive deep into further chemical and combustion properties of hydrogen to study its impact on process safety in design and operation phase of engineering project involving production, storage transport and utilization of hydrogen.

 Chemical and combustion properties-

How H₂ behaves at ambient temperature and how it reacts with other metals & non-metals…

At ambient temperature the hydrogen reaction with oxygen is extraordinarily slow unless it is activated by catalyser or spark, once reaction activated by spark it can turn in to high rate ignition or explosion depending upon the surrounding physical condition and concentration of H₂ and O₂ .Hydrogen reacts both with non-metals (high electro negativity) and with metals (low electro negativity) to form either ionic or covalent hydrides (e.g. HCl, H2O). The electro negativity of hydrogen is 2.20 (Pauling scale) this makes hydrogen most reactive compared to others. Hydrogen can react chemically with most other materials. This property of hydrogen needs to be understood in depth to ascertain physical and chemical compatibility of metals/non-metals/other materials like composites while selecting materials for handling of pressurized /liquid hydrogen.

Flammability range/limits of hydrogen (4.1% to 72.5% vol in air)-

 Hydrogen in connection with oxygen is flammable over wide range of 4.1% to 72.5% compared to natural gas and other petroleum products and it can become explosive within wide range of concentration i.e. 18% to 59% at standard atmospheric conditions. We may draw misleading conclusion that handling and utilization of hydrogen is not as safe as natural gas and other petroleum product due to its very wide flammability range instead in actual/practical cases H₂ will rarely reach the limit of its higher flammability limit if handled in well ventilated premise due to its higher diffusivity-coefficient, high buoyancy and smaller molecular weight which helps H₂ to disperse quickly in case of leak (H₂ is 14 time buoyant than air while natural gas is 4 times). This means that same quantity of hydrogen in gaseous form will escape at 4.6 times faster than natural gas .The flammability range of petroleum on lower threshold is only 1.2% while hydrogen has advantage up to 4.1%.

We can say that in well-ventilated unconfined space the probability of hydrogen forming explosive mixture is much less than liquid petroleum product and relatively lesser than natural gas. Early detection of leaks is critical for preventing accidents, protecting workers and the public, and avoiding potential damage to infrastructure. Hydrogen leak-detection systems employ technologies such as sensors, detectors, and monitoring equipment to identify leaks promptly. Hydrogen leaks are scientifically defined in ASME B31.12 as Grade-1,2 &3 along with its readings and mitigation measures in hydrogen value chain as below. This can be used to decide/design the location of hydrogen leak detection sensor and their sensitivity along with firefighting/hazard mitigation response in case of unlikely event.

The flammability mixture to an extent depends upon the temperature, pressure and direction of propagation of hydrogen flame. The variations are explained well in table mentioned below (table-2.1). These results are drawn out of laboratory experiment conducted at specific laboratory conditions hence actual limits may vary slightly depending upon concentration, temperature and pressure. Hence, it’s important to build in designed factor of safety while designing process safety equipment for storage and handling of hydrogen.

Practically the flammability limit of hydrogen depends upon the instrument & standard method used for measurement. The table 2.2 below mentions about the LEL & UFL of H₂ for various international standards.

Another factor worth paying attention to here is effect of mixture temperature (H₂ & Oxygen) on LFL&UFL of hydrogen. The flammability ranges of hydrogen changes linearly in proportion to change in temperature. LEL will decrease by about 2.5% by volume (from 4% -1.5% by volume) with increase in mixture temperature from 20⁰C to 400⁰C .UFL increases more significantly by about 12.5% by volume for the same change of mixture temperature.

The effect increase of mixture pressure is different for LFL and UFL. In case of LFL value decreases to 5.6% for increase in pressure from 0.1-5.0MPa then is constant up to pressure of 15MPa. For UFL changes and not linear, UFL decrease from 76% to 71% for changes in pressure from 0.1 to 2.0 MPa then increase from 71% to 73.8% with pressure increase from 2.0 to 5.0MPa  again decreases significantly from 73.8% to 72.8% with pressure rise from 5.0 to 15.0MPa. Please ref to the graph mentioned below for better understanding of effect of pressure and temperature.

Hydrogen gas does not have a flash point as it is already a gas at ambient conditions. It means that cryogenic hydrogen will flash at all temperatures above its boiling point of 20 K (-253⁰C).

The comparative view of flammability range of Hydrogen, Methanol, Petroleum and Natural gas is provided as below. Practically wide flammability range of H₂ makes it more efficient fuel for wide range of heat and power applications at the same time process safety of hydrogen must be designed keeping this in mind because this advantage is coupled with disadvantage while handling of H_2.

Limiting Oxygen Index-

As we know that oxygen, fuel (liquid/gas) &Ignition sources are required to complete fire triangle so that fire is initiated. In controlled fire scenario engineering process and controls are used to control either oxygen/ fuel proportion to control the flame and heat generated out of flame. In case of hydrogen, next question comes in our mind is what is that minimum % of oxygen required for propagation of hydrogen flame and generate heat. Answer is no mixture of hydrogen, air& nitrogen at NTP will propagate the flame if mixture contains less than 5% of oxygen by volume (NASA -1997).

Ignition Properties of hydrogen-

Now let’s see how flammable hydrogen air mixture (usually  non- stoichiometric mixture) can be ignited for purpose or by accident, once we understand how hydrogen & air mixture can get ignited we can make efforts to understand how to keep it safe in storage and handling and utilization.

The minimum energy required to ignite the hydrogen +air mixture is called Minimum Ignition Energy (MIE) which is 0.02 mJ only. As this value of MIE is very low even compared with other hydrocarbon fuels it can easily be created by mechanical spark created by rapidly closing of valve, electrostatic discharge in ungrounded particulate filters, spark from electrical equipment, catalyst particles, heating equipments, Lightning strike near the vent stack. Hence it is of utmost importance to eliminate or isolate the source of spark in appropriate way from hydrogen system as if unforeseen ignition sources could occur.

Needless to say that less ignition energy is required as mixture is closer to stoichiometric level as well it depends upon temperature, pressure and composition. Practically all ignition sources generate energy more than 10 mJ hence any ignition source or spark can ignite the mixture of hydrogen and air.

As hydrogen is essentially an electrical insulator at both liquid and gaseous state, flow of hydrogen will generate the static electricity similar to other hydrocarbon fuel which can lead to generation of spark if not grounded to equalize potential of all hydrogen handling equipment. These properties of static electricity generation can be become more serious in the event of high flow rate and longer blow down time from hydrogen storage.

Auto ignition temperature of hydrogen is above 510⁰C which is relatively higher than hydrocarbons having longer molecule.  Objects at temperature of 320⁰C can ignite the hydrogen after prolonged contact. Comparative chart is provided below to compare the auto-ignition temperature of hydrogen with other fuels.

What happens if Hydrogen & air mixed gets in contact with spark –Travel from spark to explosion.

So far we were looking how we can keep hydrogen in its containment which is designed to store and carry. Now we will try to understand what technical properties of hydrogen as fuel in the gaseous and liquid phase are vital if it gets in contact with sparks.

Burning Velocity-Velocity indicating the speed with which smooth plane combustion wave can advance into stationary mixture. It is pertinent property of gas which is depending upon temperature, pressure and concentration. The burning velocity of hydrogen in air at stoichiometric (29.4% vol. of H₂) ambient conditions is 2.55 m/s reaching a maximum of 3.2 m/s at a concentration of 40.1%, which would even increase to 11.75 m/s in pure oxygen. It is interesting to note than burning velocity is maximum at 40.1% concentration rather than at stoichiometric conditions. This effect of shifting occurs due H₂ property of higher molecular diffusivity. It is interesting to note that higher diffusivity of hydrogen is actually the beneficial property of hydrogen as long it is not in contact with sparks because this property prolongs the hydrogen-air reaching to LEL limit in unconfined space. However, once hydrogen is ignited it acts as flame propagator which is not safe while handling hydrogen in entire value chain.

The higher the burning velocity, the greater the chance for a transition from deflagration to detonation (DDT). Needless to say that diffusivity of hydrogen property has double edge (beneficial & harmful) in hydrogen process engineering design. The laminar burning velocity (burning velocity) as function of concentration if hydrogen in air is shown in the graph mentioned below.

Flame propagation Speed- This is deflagration front velocity relative to fixed observer is given by speed of sound in combustion products which is 975m/s for stoichiometric hydrogen air mixture.

Detonability limits – Detonation is worst case scenario of hydrogen accident .The detonation range mentioned in technical report   ISO- 15916/2004 is 18-59% by volume of hydrogen in air. The detonation range varies on size of tube used for experiment. By conservative generalization of available data suggest the detonation range of hydrogen is within 11-70% (flammability range is 5%-75%). This is narrower and as expected within the range of flammability and that’s the cause of worry to process designer while designing the containment to store and carry hydrogen.

The time in which the flame at the ignition point develops to a detonation depends on many parameters such as temperature, pressure, mixture composition, geometry and ignition source strength. For a stoichiometric hydrogen-air mixture to detonate.

The explosion of a hydrogen-air mixture cloud results in the formation of a pressure wave, which is different and dependent on the combustion mode (slow/fast/detonation). In the deflagration of a free hydrogen-air gas cloud, the maximum overpressure is in the order of 10 kPa.

At 7 KPa pressure-   People would fall to the ground.

35KPa pressure-      Damage of ear drum is expected.

240 KPa pressures- Above which fatalities must be considered.

 Emissivity* of hydrogen flame (less than 0.01) -The thermal energy radiated from a flame corresponds to the higher heating value (HHV). Emissivity of Hydrogen flame is less than 0.1 unlike hydrocarbon is approximately 0.2 to 0.3 for lighter hydrocarbon. Hence radiations emitted from hydrogen flame are lesser than hydrocarbon. Therefore despite high flame temperature the burning hazard of hydrogen is comparatively small. Hydrogen flame has major problem in its non-visibility even in dark room unless impurities in the air are present. Another advantage is no smoke generation by hydrogen flame hence its comparatively safe in confined areas.

*Emissivity- The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation.

 Safety measures to avoid detonation is extremely important. While deflagration of quiescent stoichiometric hydrogen air mixture in open atmosphere generates pressure wave of only 0.01MPa (below level of eardrum injury), the detonation of same mixture would be accompanied by blast of more than magnitude of higher pressure of about 1.5MPa (far above the fatal pressure of about 0.08-0.10 MPa).

Comparison of hydrogen with other fuels-

Hydrogen is unusual fuel; the leak of lower flow rate of hydrogen supports combustion as compared to other hydrocarbon fuels. H₂ has lowest molecular mass, lowest density and lowest viscosity. These properties of hydrogen are turning in its favor for quick escape for confined space at the same time

 The other properties of hydrogen which are required to understand from process safety point of view and their comparison is provided in table below.

Carbon dioxide is a gas essential in the production of many everyday products, including food and beverages as well as being a key raw material in the fertilizer industry.

However, these days, carbon dioxide hits the news headlines for all the wrong reasons. According to a report issued by the Royal College of Physicians several years ago, in 2013 the concentration of carbon dioxide in the atmosphere had increased by about 42% over the levels before the industrial revolution, and the concentration continues to rise.

Carbon dioxide is one of the main gases causing the Earth to overheat. Much is spoken about the CO2 emitted by vehicles in the automotive sector; however the main culprit is energy and heat generation. In 2020 electricity and heat production accounted for over 15 billion tonnes of CO2 emissions, with transportation in second place at just over 7 billion tonnes. Ask most industrial companies why they have sought to reduce energy usage in recent years and fiscal reasoning would be top of the agenda for many firms.

We have seen huge increases in the cost of electricity in recent years, especially in Europe as geopolitical and economic pressures bear down heavily on the price of oil and gas. However, another reason, high on the agenda of many fortune 500 companies is the desire to reduce their carbon footprint, ensuring we leave this planet in good order for our children and future generations.

When it comes to reducing energy use on a large industrial complex, low hanging fruit such as low energy light bulbs and movement sensors have already been initiated. The more difficult areas are associated with the production itself, elements that require elevated temperatures can be better insulated, as indeed can refrigerated areas, but mechanical machines themselves can prove difficult to improve in terms of efficiency without affecting production. One element that is found on most manufacturing sites is the need for compressed air.

Pneumatics are a 1/2 common theme and used in all sorts of industrial applications. To deliver the compressed air, a compressor or number of compressors are employed, and the resulting air is delivered around a site by a system of air lines. These pipes are often above ground to improve logistics and ergonomics of production, however over time they can degrade and give rise to leaks. Elbow joints, reducers, condensers, and other fixtures all have the potential to leak air under pressure. With hundreds of metres of pipework, these leaks can often be difficult to detect. Teledyne FLIR are a global producer of high quality analytical handheld devices, including both thermal and acoustic imaging cameras.

Released earlier this year, the FLIR Si2-LD acoustic camera makes light work of identifying leaks in pipework, even those elevated air lines that are difficult to access. By simply pointing the camera at an airline it can detect leaks of 0.05 litres per minute at a distance of 10 metres. At 2.5 metres, leaks as little as 0.0032 litres per minute can be detected. These may not sound like very big volumes, but over the course of a year the loss can be considerable.

On the FLIR Si2-LD, air leaks are displayed on the high definition five-inch colour screen, by simply pointing the handheld device at the air line. Teledyne FLIR not only produce a wide range of high quality cameras but also provide the associated software to facilitate the collection and analysis of data. The FLIR Si2-LD camera is loaded with such software. Using a system termed Industrial Gas Quantification, the camera can calculate the monetary loss incurred for each leak identified. As well as air, the software can also calculate losses for a variety of other gaseous systems including ammonia, helium, hydrogen, argon and carbon dioxide. If your company is one of the many thousands, that are concerned about their carbon footprint then reducing electricity usage through eliminating air leaks might prove to be an example of low hanging fruit. The Si2-LD from FLIR is a vital tool is facilitating this move to protect our environment. To find out more about the SI2-LD acoustic camera and other instruments in the Teledyne FLIR range please contact your local agent or your FLIR distributor

Intrinsic safety (IS) is a critical design and operational principle in instrumentation used within the mining industry. Mines are often classified as hazardous areas due to the presence of flammable gases, combustible dust, or reactive substances. Intrinsically safe instrumentation is engineered to operate with energy levels below those capable of igniting such volatile environments, ensuring that safety and operational efficiency are not compromised.

One primary advantage of intrinsic safety is the reduction of explosion risks. In mining, where methane and coal dust explosions are a constant threat, IS-certified devices prevent sparks or overheating that could trigger catastrophic events. This protection extends to maintenance and diagnostics, allowing equipment to be safely inspected and serviced without de-energising systems or disrupting operations.

Another key benefit is compliance with international safety standards, such as IECEx and ATEX, which mandate IS compliance for hazardous locations. By employing IS-certified instrumentation, mining operators demonstrate adherence to these standards, minimising legal liabilities and enhancing worker safety.

The reliability of intrinsically safe instruments is also crucial. Pressure transmitters, for example, are pivotal for monitoring equipment performance and environmental conditions in mining. Malfunctioning devices could lead to system failures or unsafe conditions. IS technology ensures these instruments maintain accuracy and reliability, even under extreme conditions, without posing ignition risks.

Moreover, the use of IS instrumentation fosters cost savings over time. By eliminating the need for heavy explosion-proof enclosures or purging systems, IS solutions streamline equipment design and installation, reducing both capital and operational expenses.
