DSEAR Risk Assessments &
Hazardous Area Classification
Practical, operationally focused DSEAR consultancy for industrial and commercial sites across the UK.
What is DSEAR and Do You Need an Assessment?
DSEAR stands for the Dangerous Substances and Explosive Atmospheres Regulations 2002. It requires UK businesses that store, use, or produce flammable or explosive substances to identify hazards, assess the risk of fire and explosion, and put control measures in place.
If your site handles flammable liquids, gases, vapours, dusts, or charges large lithium-ion batteries, you are likely required to carry out a DSEAR risk assessment.
Hielaman delivers practical, operationally focused assessments that meet your obligations under ACOP L138, EI15 and BS EN 60079, with clear, insurer-friendly reporting your team and regulators can act on.

Full DSEAR Risk Assessments
We carry out comprehensive DSEAR risk assessments for industrial and commercial sites across the UK. Our assessments identify all dangerous substances on site, evaluate the risk of fire and explosion, and provide clear, actionable control measures. Reports are written to meet the requirements of ACOP L138 and are structured to satisfy insurers, the HSE, and fire authorities.
Hazardous Area Classification (HAC) Studies
Hazardous area classification identifies locations where explosive atmospheres may occur and defines the zones that require ATEX-rated equipment. We carry out HAC studies in line with EI15 and BS EN 60079, producing detailed zone drawings and equipment schedules that give your team and insurers a clear picture of risk across your site.
Flammable Liquid & Gas Storage
Storing flammable liquids or gases on site introduces significant fire and explosion risk. We assess storage areas, bunded tanks, dispensing points and associated pipework against DSEAR requirements, identifying control measures and ensuring your storage arrangements meet regulatory and insurer expectations.
Spray Booths & Paint Spraying Operations
Spray booths and paint spraying areas involve flammable solvents, vapours and ignition sources that require careful DSEAR assessment. We assess spray operations, paint mixing rooms, flammable product storage and ignition control measures, helping you manage risk and meet your legal obligations under DSEAR and associated fire safety legislation.
Battery Charging & EV Charging Risk Assessments
Battery charging areas and EV charging infrastructure introduce hydrogen gas release, thermal runaway risk and ignition hazards that fall under DSEAR. We assess battery charging rooms, lithium-ion battery systems and EV charging installations, providing practical risk assessments and control measures to keep your site compliant and safe.
LPG & Natural Gas Installations
LPG and natural gas installations present explosion and fire risks that must be assessed under DSEAR. We assess LPG storage, pipework, regulators, appliances and associated hazardous areas, ensuring your installation is correctly classified and that appropriate control measures are in place to protect your site and meet regulatory requirements.
ATEX Inspections
Equipment used in hazardous areas must be ATEX rated and maintained in a way that preserves its certification. We carry out ATEX inspections to identify non-compliant equipment, assess installation standards and produce inspection records that demonstrate due diligence to insurers, the HSE and fire authorities.
Combustible Dust Risk Assessments
Combustible dusts generated by processes such as wood working, food production, recycling and chemical handling can create explosive atmospheres that fall under DSEAR. We assess dust generating processes, extraction systems, accumulation risks and ignition sources, providing practical control measures to reduce the risk of dust explosions on your site.
Hazardous Area Drawings
Accurate hazardous area drawings are a core output of any HAC study and a key document for demonstrating DSEAR compliance. We produce clear, detailed zone drawings that show the extent and classification of hazardous areas across your site, suitable for use by contractors, equipment suppliers, insurers and regulatory authorities.
