The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) Explained


What are DSEAR and what do they cover?

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) are a legal requirement that covers the risks of fires and explosions caused by dangerous substances in the workspace. Every employer who stores, produces, or handles fuel and oil, along with other potentially hazardous chemicals, is required to comply with the DSEAR regulations. This is to ensure the safety of all employees and the business itself. That includes the risk caused by gasses under pressure and substances corrosive to metals, flammable gasses, dust from machine operations, different paints, solvents, and varnishes (HSE, 2022).

Why do you need a DSEAR inspection?

Regardless of your business size, your health and safety procedures are there to protect your employees’ wellbeing and your workspace integrity.
