What is DSEAR Compliance?
The Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) require employers to assess and manage the risks associated with flammable gases, vapours, mists, and combustible dusts.
Compliance involves:
Identifying dangerous substances and processes
Assessing the risk of fire and explosion
Classifying hazardous areas into zones
Implementing control measures to reduce risk
Verifying that equipment and installations are safe
Training personnel to understand the hazards at their workplace, and their role in managing them
A structured approach to DSEAR compliance improves safety, reduces risk, and supports efficient operations.
Our DSEAR Compliance Services
We provide a complete range of services to support DSEAR compliance at every stage:
DSEAR Risk Assessment
A DSEAR risk assessment is an evaluation of the likelihood and severity of the hazards presented by dangerous substances in the workplace. The definition of a dangerous substance with some examples can be found here. DSEAR is primarily concerned with the fire and explosion hazards, but an often overlooked requirement is to also assess energy releasing events (such as inert gas cylinders acting as projectiles due to leaks) and corrosion which could lead to a fire, explosion, or energy releasing event.

Hazardous Area Classification (HAC)
Hazardous area classification (HAC) is used to identify areas where explosive atmospheres may exist (these are known as hazardous zones or areas), and specify an extent in which ignition sources should be controlled.

DSEAR Verification
A DSEAR Verification (or DSEAR Verification of Overall Explosion Safety) is a legal requirement under Regulation 7(4) of DSEAR which must be performed before an installation is used for the first time. It applies to any installation where explosive atmospheres may be present. It’s purpose is as a final check on a process to ensure that hazards have been appropriately identified and mitigated to allow its safe operation, and that the facility can operate in line with the requirements of DSEAR.

DSEAR Assessment Review
A DSEAR gap analysis and peer review provides an independent and objective evaluation of your existing DSEAR assessment and management system to check that it is accurate, compliant, and aligned with industry good practice. A peer review is often requested when organisations are conducting their own DSEAR assessments for the first time and may not be confident in their experience, or if a 3rd party has supplied a generic DSEAR assessment with an item or package of equipment. We are independent and objective, with no affiliations with any equipment manufacturers or suppliers.
