DSEAR Risk Assessments

DSEAR (Dangerous Substances and Explosive Atmospheres Regulations) requires that a hazard must be present – this is usually the presence of an explosive atmosphere and an effective source of ignition.

The key requirements for complying with the regulations revolve around the completion of a thorough risk assessment and the undertaking of a Hazardous Area Classification (HAC).

Ultimately, the assessment aims to provide a coherent focus for the identification and mitigation from:

flammable substances with explosive and oxidising properties alongside substances corrosive to metal
substances that can create explosive atmospheres
work activities involving other substances that could create a fire, explosion or similar energetic (energy releasing) event e.g. runaway exothermic reactions, decomposition of unstable substances, dust explosions.
the occurrence of industrial incidents caused by fires and explosions
