CSA M422-2012

Fire-performance and antistatic requirements for conveyor belting

This is the second edition of CSA M422, Fire-performance and antistatic requirements for conveyor belting. It supersedes the previous edition published in 1987 . This Standard specifies fire-performance and antistatic requirements for new (unused) conveyor belting for use in any part of a mining or excavation operation that is below the surface.This Standard covers fire-performance and antistatic conveyor belting of the following types:
(a) Types A1 and A2 intended for use in explosive atmospheres; and
(b) Types B1-A, B1-B, B2, and C intended for use in non explosive atmospheres.This Standard does not cover products of combustion or products of thermal degradation from conveyor belting subjected to fire or heating.
Note: While the intent of this Standard is to establish a reasonable level of fire-performance for conveyor belting, it is recognized that any conveyor belt material could burn under conditions different from those described in this Standard. Therefore, to ensure a higher level of fire safety, consideration should be given to installation measures such as those listed in Annex A.
