DSEAR Risk Assessments
DSEAR, meaning Dangerous Substances and Explosive Atmospheres Regulations 2002 requires employers to assess the risks of fires and explosions that may be caused by dangerous substances in the workplace. The aim is to protect employees and other people who may be put at risk, such as visitors to the workplace and members of the public.
Hazardous areas are defined in DSEAR as "any place in which an explosive atmosphere may occur in quantities such as to require special precautions to protect the safety of workers". ... Zone classification is a way of analysing the environment to classify where gas explosive atmospheres may occur.
HSE recommends that a companies’ DSEAR is updated between 3-5 years and is dependent upon the risk levels of the company and operation.
