Hazardous Area Classification (HAC)

Ensure safety by categorising areas with potentially explosive atmospheres to guide the selection of appropriate equipment and safety protocols.


What is Hazardous Area Classification (HAC)?

Hazardous Area Classification (HAC) is an essential requirement under the DSEAR (Dangerous Substances and Explosive Atmospheres Regulations 2002) and ATEX Directive used in industrial and commercial settings to identify and categorise areas where the presence of flammable gases, vapours, liquids, combustible dust, or other potentially explosive or hazardous materials may pose a risk to personnel, equipment, and facilities.

This classification framework is instrumental in ensuring the implementation of appropriate measures to prevent or mitigate the risk of ignition and subsequent incidents. It provides clear guidance for selecting and installing equipment that aligns with the relevant safety standards and protection methods specific to each zone category, emphasising the importance of purposeful design to minimise the potential for ignition sources.
