(B) All diesel-powered equipment shall be attended in underground mines while in operation or when the engine is running.

(C) Inby and outby diesel-powered equipment may be used in underground mines if the inby or outby diesel-powered equipment uses an engine approved or certified by MSHA, as applicable, for inby or outby use, that when tested at the maximum fuel-to-air ratio, does not necessitate an MSHA 30 C.F.R.
