Safety Code G - Flammable gases & CERN flammable Gas Safety Manual (1996)
en
fr
This code establishes regulations for the purchase, transport, storage, distribution and use of flammable gases at CERN, to protect users and others inside and outside CERN. It si particularly directed at the regulation of the use of gases in experimental installations for the detection of particles, for which industrial rules do not exist.
It is supplemented by the Flammable Gas Safety Manual prepared to help users, especially experimental teams. This manual is in two sections: the first devoted mainly to the formal requirements necessary for the design, operation and maintenance of installations, including risk classification and the official forms which have to be completed. The second section details the rules and good practice and refers to other codes pertinent to the safe use of flammable gases.

replace the corresponding provisions of Safety Code G.
For existing activities without binding occupational exposure limit, the
organic unit concerned shall implement the provisions of Safety Regulation
SR-C, General Safety Instructio GSI-C2 and other related General Safety Instructions not later than 1
January 2012. Until such implementation, the corresponding provisions of
