The Environmental Protection Agency (EPA) has approved a Code of Practice called “Code of Practice for Flammable Gases and Oxygen Tank Wagons” (HSNOCOP 29-1).

The purpose of this code is to provide an acceptable solution for the design and construction of tank wagons for the conveyance of flammable gases and oxygen by road.  It applies to vehicles constructed after 1st July 2008 and which are required to comply with the Hazardous Substances and New Organisms Act 1996, the Hazardous Substances (Tank Wagons) Regulations 2004 and other Hazardous Substances Regulations as applicable.

Vehicles designed and constructed before 1st July 2008 may still comply with the Department of Labour’s LPG Tank Wagon Code.
