6.1. Track equipment, such as track cleaners,
				track drills and cutting machines, and track-mounted roof bolters that do not
				create any greater than ordinary risk of fire may operate normally, provided:
6.1.1. No less than twelve (12) inches of
				radius clearance is maintained between trolley or feeder wires while such
				aforementioned equipment is being transported or trammed. If less than 12
				inches of clearance cannot be met then the provisions under 6.1.b.1 would
				apply.
6.1.2. Within eight (8)
				hours prior to such equipment move trolley wire crossovers and switches located
				on the equipment travel route shall be examined for proper clearance by a
				certified foreman or fireboss and the following necessary safety precautions
				implemented.
6.1.2.a. Required Clearance
6.1.2.a.1. When such aforementioned equipment
				passes under energized trolley, feeder wires, or high voltage cables at
				crossovers and switches and 12 inches of radius clearance cannot be provided
				such trolley or feeder wires, or high voltage cables shall be adequately
				guarded to prevent accidental contact.
6.1.2.a.2. However, where it becomes
				necessary for the equipment to pass under bare trolley, feeder wire or high
				voltage cable and six (6) inches of clearance cannot be maintained the wire may
				be either de-energized and locked out with an approved device and tagged out by
				a certified electrician or remain energized and all people in by on the same
				ventilating current of air brought out by the move area.
6.1.2.b. Where it becomes necessary for the
				equipment to pass under high voltage cables and/or insulated D.C. feeder wires
				and the six (6) inches of required clearance cannot be maintained, the
				aforementioned high voltage cables and/or insulated D.C. feeder wires shall
				either be channeled above the level of the roof line, or de-energizing by
				locking out and tagging out by a certified electrician.
6.1.3. Booms on the track cleaners shall be
				insulated on the trolley and feeder wire side and a means installed on the

				shall be maintained between such equipment operator and the dispatcher or a
				designated qualified person on the surface and the affected section.
6.1.5. While roof bolting operations are

				trolley and/or feeder wires shall be adequately guarded to prevent accidental
				contact.

				above criteria cannot be complied with, no person except such persons directly
				involved with the above moving equipment shall be permitted to be in by such
				equipment while on the same ventilating split of air.
