This standard explains the HAZCHEM* system which is commonly used for conveying information to emergency services in connection with the transport and handling of hazardous substances. The system provides for correct immediate response action in the event of fire or spillage so as to minimize the hazards to people and the local environment. It is therefore recommended as the primary reference for the emergency services.
NOTE: It should be stressed that this simple coding system, comprising a numeral followed by one or more letters, provides only for initial emergency actions and is intended to be augmented by the seeking of additional, specialized advice.
