DSEAR is designed to protect people from the risks of dangerous substances in the workplace. These substances can ignite, explode, or corrode equipment if not properly managed — putting staff, the public, and property at risk.
A suitable and sufficient DSEAR assessment helps you:
present in your operations.
using appropriate control measures.
with proportionate response plans.
so everyone understands their responsibilities.
to control ignition sources safely.
Dangerous substances include any materials that can cause harm if released, ignited, or improperly controlled. Examples include:
Solvents, paints, varnishes, and LPG
From machining, sanding, or food processing
Stored or used in industrial or laboratory settings
That may damage metal components or systems
Our DSEAR-qualified assessors provide comprehensive, site-specific evaluations covering all aspects of risk identification, management, and control. Our services include:
Site-specific reviews of processes and substances to identify potential fire, explosion, and corrosion hazards.
Define and map zones under BS EN 60079 to prevent ignition sources in potentially explosive atmospheres.
Provide practical, proportionate recommendations to meet HSE and DSEAR regulatory expectations.
Develop effective controls, safe operating procedures, and inspection regimes to minimise risks.
Establish clear emergency arrangements to manage spills, leaks, or accidental releases safely.

Professional insights from our process and fire safety specialists.
A DSEAR assessment identifies and controls risks from dangerous substances that could cause fire, explosion, or corrosion, ensuring compliance with the Dangerous Substances and Explosive Atmospheres Regulations 2002.
Any business that stores, handles, or uses flammable or explosive substances — from industrial plants to laboratories and workshops — must complete a suitable and sufficient DSEAR assessment.
HAC defines where explosive atmospheres may occur and the frequency of their presence. Zones 0, 1, and 2 (gases/vapours) and 20, 21, and 22 (dusts) determine the safety controls and equipment requirements.
Every three to five years, or sooner if there are significant changes in materials, processes, or plant layout.
A clear summary of identified hazards, zone maps, photographs, and prioritised recommendations — giving you a practical action plan for compliance.
Protect your people, property, and processes with confidence.
