Part 36 Mining

Section 598 Fire resistance

Conveyor belting and other conveyor components used in areas with high fire and explosion potential must be closely controlled. One standard that can be referenced for additional information is CSA Standard CAN/CSA 422-M87 (R2007), Fire-Performance and Antistatic Requirements for Conveyor Belting.

The Standard addresses two categories of conveyor belts:

(1) Types A1 and A2 intended for use in explosive atmospheres; and
(2) Types B1-A, B1-B, B2 and C intended for use in non-explosive atmospheres.

The Director may use an equivalent standard where appropriate.

The use of non fire-resistant belting is allowed in a hazardous location provided the conveyor belt system is equipped with an effective fire suppression system approved by the Director.
