Provides recommendations on the selection, installation and maintenance in hazardous areas of electrical apparatus which is certified or assessed in accordance with the requirements of type of protection 'd' - Flameproof enclosure. It does not apply to the underground mining industry, although the code may be applicable to certain parts of surface mining industries. For the purpose of this code, explosion risks due to the presence of combustible gases and vapours only are considered.

This Part of the Code applies to the concept of ensuring electrical safety in hazardous areas by means of Type of Protection 'd': Flameproof Enclosure, and offers guidance on the selection, installation and maintenance of this type of electrical apparatus.The recommendations of the code do not apply to the underground mining industry, where other precautions are necessary, though it is recognized that the recommendations of the code may be applied to the surface installations of mines.For the purposes of this Part of the code, explosion risks due to the presence of combustible gases and vapours only are considered. Combustible dusts are therefore excluded except where otherwise noted (see also Part 10).
