Which regulation is specifically referenced as relating to dangerous substances and explosive atmospheres?

• A. Dangerous Substances and Explosive Atmosphere Regulations 2002
• B. The Management of Health and Safety at Work Regulations 1999
• C. Control of Substances Hazardous to Health Regulations 2002
• D. The Health and Safety at Work Act 1974

Answer: (A)

Dangerous substances and explosive atmospheres are addressed together in a regulation that sets out explicit duties for identifying and controlling risks from dangerous substances and from potentially explosive atmospheres in the workplace. This regulation requires employers to carry out risk assessments, eliminate or reduce risks where possible, ensure safe handling, storage and use of dangerous substances, control ignition sources, maintain equipment, and provide information, training, and emergency arrangements. It is the only regulation that specifically targets both dangerous substances and explosive atmospheres, which is why it’s the best answer.

The other regulations play important roles in workplace safety but are broader or cover different areas. General health and safety risk assessment and management principles underpin all work activities, COSHH focuses on hazardous substances more generally (not specifically explosive atmospheres), and the Health and Safety at Work Act provides the overarching legal framework rather than targeted provisions on dangerous substances and explosions.
