Policies, Procedures & Guidance

Dangerous Substances and Explosive Atmosphere Regulations

Dangerous substances are substances that can put safety at risk from fire, explosion, and the corrosion of metal. These risks need to be considered and managed in a specific way to comply with legal requirements.

Chemicals/substances are commonly assigned with a classification based upon the manner in which they pose a hazard to people. For the term “hazardous” RGU is identifying that the substance has the potential to have a detrimental impact on the health of a person and creates a health hazard.

The less common term ‘dangerous’ indicates that the substance can have a detrimental impact on the safety of a person and creates a physical hazard. Dangerous substances are defined as those that are either explosive, oxidising, extremely flammable, highly flammable or flammable and need to be managed in a specific way to mitigate their hazards.

To help Schools/Departments whose activities require the use of dangerous substances, RGU has implemented a DSEAR Assessment template to help undertake and record a suitable and sufficient assessment of the risk. In conjunction with DSEAR Assessment guidance this will provide confidence in DSEAR compliance.
