Abstract

Specifies safety requirements for diesel engine systems that are explosion-protected for use in underground coal mines, including use in explosion-risk zones. It implies limited time safe operation in atmospheres containing up to 1% methane.

Scope

This Standard specifies safety requirements for diesel engine systems that are explosion-protected for use in underground coal mines, including use in explosion-risk zones.
NOTES:
1 Compliance to this Standard implies a limited time safe operation in atmospheres containing up to 1 percent methane, including -
(a) the control of surface temperature, to avert ignition of coal dust that could settle on a hot surface;
(b) containment or elimination of flames and sparks that could ignite flammable gases and dust that may be present (such as in underground coal mines); and
(c) control of diesel emissions.
2 This Standard also addresses inadvertent short-term exposure to high methane levels and any consequent abnormal combustion.
3 Appendix A gives guidance for demonstrating compliance with this Standard.
