    Note that the 60079 series of standards will gradually address dust hazards as well as gas/vapour hazards. The standard number will have an additional suffix 1 or 2. Thus, for example, 61241-14 (see below) will be replaced by 60079-14-2 [installation for equipment in dust hazards], with 60079-14-1 dealing with installations in gas/vapour hazards.
