Sigma-HSE We provide actionable solutions to ensure and maintain process safety in the work environment.

Sigma-HSE Ltd is a group of companies focused on the provision of technical services to industry in the fields of Health & Safety and the Environment. Our specialist testing laboratory in Wi******er generates test data on the flammability, explosivity and reactivity of dusts, liquids, gases and vapours. Our scientists and technicians are experts in this field and can quickly assess your dust testing needs including Explosion Severity (Pmax and Kst, Minimum Explosive Concentration (MEC) and Limiting Oxygen Concentration (LOC)), Ignition Sensitivity (Minimum Ignition Energy (MIE), Minimum Ignition Temperature (MIT) and Layer Ignition Temperature (LIT), Thermal Stability (Bulk Powder Diffusion / Aerated Bulk Powder Diffusion Cell, Air Over Layer and Basket Safe Storage Temperature Testing) as well as Electrostatic Hazards (Powder Volume Resistivity and Charge Relaxation Time). Our Liquids, Gas and Vapour testing facility features tests such as Liquid Conductivity, Lower & Upper Flammable Limits (LEL / UEL), Flashpoint and Auto Ignition Temperature (AIT). All laboratory testing is rigorously controlled to comply with the latest versions of European and International test standards. Supporting the laboratory and providing on-site support is our dedicated team of Process Safety Consultants working from our offices in Europe, Asia and the Middle East. Our range of specialist technical safety assessments including Comprehensive Safety Audits, HAZOP, DSEAR / ATEX, HAC, QRA, EPD, LOPA, SIL as well as training, and incident investigation.

How old is your DSEAR assessment?

DSEAR assessments help businesses identify and manage the risks associated with dangerous substances, flammable atmospheres, and combustible dusts.

But if your processes, materials or equipment have changed, does your assessment still reflect the risks present today?

At Sigma-HSE, we help businesses review their fire and explosion risks and ensure their control measures remain appropriate.

Is your DSEAR assessment due a review?

What works safely at lab scale may not be safe at production scale.

As chemical processes are scaled up, risks can change significantly - and relying on a single test or assumption can leave critical gaps in your Basis of Safety.

Our insightful blog explores how thermal screening, reaction calorimetry and adiabatic testing can work together to build a more robust, scalable approach to process safety.

Does your process generate dust?

Dust is often an unavoidable part of industrial manufacturing, but that doesn’t mean the risks should be overlooked.

Whether it’s generated during grinding, milling, cutting or material handling, combustible dust can create serious fire and explosion hazards if the right conditions are present.

Understanding the properties of your material is an important starting point, but effective dust risk management also means looking at how that material behaves within your process.

At Sigma-HSE, we combine specialist combustible dust testing with process safety expertise to help businesses identify hazards, assess the risks and put practical controls in place.

Could your process be creating a dust explosion risk?

What is process safety?

Process safety is the systematic approach used to prevent fires, explosions, and the release of hazardous substances within industrial operations.

It focuses on identifying potential hazards in processes, assessing the risks they present, and implementing effective controls to prevent incidents before they occur.

Unlike general workplace safety, which often focuses on personal behaviour and day-to-day hazards, process safety is concerned with the integrity of systems, equipment, procedures, and management practices that keep operations safe.

It is essential for protecting people, the environment, and business continuity—especially in industries handling chemicals, dusts, gases, or other hazardous materials.

Strong process safety isn’t optional—it’s fundamental.

Battery manufacturing is scaling rapidly, but that growth brings significant process safety challenges.

From combustible dust generated during powder and metal handling to the risk of thermal runaway within battery cells, understanding the hazards is essential to designing safer processes and protecting people, equipment and facilities.

Do you know your non-electrical ignition risks?

In complex processes, electrical hazards are often well understood, but non-electrical risks can be much easier to overlook.

A Non-Electrical Ignition Risk Assessment (NEIRA) identifies sources of friction, heat, and sparks during normal operation, risks that can be just as dangerous as electrical equipment.

Are you confident you’ve identified all your non-electrical ignition risks? Book your NEIRA today: sigma-hse.com/contact

Gas cylinder explosion at garment factory in Ashulia, Bangladesh

A fire broke out at the F&F factory of Preeti Group in Jamgara, Ashulia, at around 6:45pm on 20th September. The incident was triggered when a gas cylinder exploded while being unloaded from a covered van within the factory boundary.

The death toll has risen to eight, after another injured person died in hospital. Multiple people were injured.

Key process safety considerations include:

🔹 LPG cylinder handling – Loading and unloading cylinders presents significant risks if containers are damaged, incorrectly handled or exposed to conditions that could compromise their integrity.

🔹 Vehicle loading and unloading procedures – The incident reportedly occurred during unloading, highlighting the need for suitable procedures, competent personnel and controls for non-routine material-handling activities.

🔹 Cylinder integrity and protection – Gas cylinders need to be protected against impact, heat and other conditions that could lead to loss of containment.

🔹 Separation and exclusion zones – The distance travelled by the cylinder demonstrates the potential consequences of a catastrophic cylinder failure. Appropriate separation from workers, vehicles, buildings and members of the public is important.

🔹 Fire and explosion escalation – Once one cylinder becomes involved in a fire, nearby cylinders can also be exposed to heat, potentially creating further hazards. Emergency arrangements should account for this escalation potential.

🔹 Off-site consequences – The incident affected people outside the immediate factory area, reinforcing the need to consider neighbouring workers, pedestrians, roads and surrounding businesses when assessing credible accident scenarios.

🔹 Emergency access – Difficulties accessing the site because of traffic and road conditions could delay emergency response. Access routes should be considered as part of emergency planning rather than treated as a separate issue.
