Sites storing dangerous substances

In compliance with the Dangerous Substances (Notification and Marking of Sites) Regulations 1990 (NAMOS), any person in control of any site or premises where a total quantity of 25 tonnes or more of dangerous substances are used or stored, or are to become used or stored, must give written notification to both the Fire and Rescue Service and the Health and Safety Executive (HSE). A dangerous substance is any substance which is dangerous for conveyance within the meaning of the Chemicals (Hazard Information and Packaging) Regulations 1993.

The HSE has produced a leaflet for duty holders responsible for sites storing dangerous substances as defined by the NAMOS regulations.
