The Dangerous Substances (Notification and Marking of Sites) Regulations 1990

Essex Fire Authority is the enforcing authority for the marking of premises containing 25
tonnes or more of dangerous substances under The Dangerous Substances (Notification
and Marking of Sites) Regulations 1990 (NAMOS). Upon receipt of a notification relating to a site controlled under the Regulations, Essex Fire Authority will inspect the premises and forward recommendations to the occupier in writing.

A further specific information inspection may be required to ensure a clear plan for
dealing with emergency incidents is in place for operational crews and that, where applicable, the premises comply with the requirements of the Regulatory Reform (Fire Safety) Order 2005.

As of the 6th April 2013 the NAMOS Regulations were amended.

The following is a brief guide to the amendment, notification process and subsequent inspection under Namos:
