DSEAR (original) (raw)

DSEAR, the Dangerous Substances and Explosive Atmospheres Regulations, 2002, is the United Kingdom's implementation of the European Union-wide ATEX directive. The intention of the Regulations is to reduce the risk of a fatality or serious injury resulting from a "dangerous substance" igniting and potentially exploding. Examples of a "dangerous substance", as defined by DSEAR, include sawdust, ethanol vapours, and hydrogen gas. The regulation is enforceable by the HSE or local authorities.
