MSHA PROGRAM POLICY MANUAL VOLUME V Subpart O Hoisting and Mantrips 75.1400 Hoisting Equipment; General A hoist used to transport person(s) shall comply with the provisions of this Section. The number of person(s) transported or the frequency of which the hoist is used to transport person(s) are not factors for compliance with this Section. Although scaffolding hoists are not equipped with safety catches, they can comply with personnel hoisting regulations. Safety systems utilizing safety belts attached to independently suspended safety lines by lanyards and rope grabs can be approved by district managers as a no less effective device to be used in lieu of safety catches. The following guidelines should be used in approving these devices. 1. Life lines must be attached to a structural member of the shaft or collar or surface facility and not to the hoist rope outrigger. 2. Life lines of at least first grade 5/8-inch nylon rope, 3/4 inch manila hemp rope, or equivalent, must be provided for each miner. 3. Substantial safety belts securely attached to the independently suspended safety lines by lanyards and rope grabs must be used at all times when embarking, disembarking or working on the platform. 75.1402 Communication Between Shaft Stations and Hoist Room A signal code shall be adopted and used, and it should be posted in view of the hoisting engineer and at all places where signals are given. Signals received by the engineer shall be repeated by the engineer when miners are to be hoisted or lowered. 75.1403 Other Safeguards The safeguards, in addition to those included as criteria in the Federal Register, may be considered of sufficient importance to be required in accordance with this Section. It must be remembered that these criteria are not mandatory. If an authorized representative of the Secretary determines that a transportation hazard exists and the hazard is not covered by a mandatory regulation, the authorized representative must issue a safeguard notice, allowing time to comply before a 104(a) October 2003 (Release V-34) 125
MSHA PROGRAM POLICY MANUAL VOLUME V citation can be issued. Nothing here is intended to eliminate the issuance of a 107(a) order when an imminent danger exists. 75.1403-3 Criteria - Drum Clutch; Cage Construction At the bottom of each hoisting shaft and at intermediate landings, a "runaround" should be provided for safe passage from one side of the shaft to the other. This passageway should be not less than 5 feet in height and 3 feet in width. Ice should not be permitted to accumulate excessively in any shaft where miners are hoisted or lowered. No person should ride a cage with equipment, supplies, or materials. This does not prohibit the carrying of small handtools, surveying instruments, or technical devices. 75.1403-5 Criteria - Belt Conveyors The requirements for the transportation of persons on belt conveyors, as outlined in this Section, shall apply when any person is transported on belt conveyors at times other than during the regularly scheduled mantrip operations. Bare pinch wires are acceptable for stopping and starting belt conveyors used to transport persons, provided that the voltage on such circuits is not more than 12 volts. A pull cord arrangement that will enable any person riding the belt to stop and start it shall be acceptable as compliance. Start switches may be located at intervals of not more than 500 feet along such belt conveyors. An official or other responsible person designated by him should be in attendance while miners are boarding or leaving belts. Ample clearance should be provided at conveyor-loadingheads and at conveyor-control panels. 75.1403-6 Criteria - Self-Propelled Personnel Carriers Self-propelled track equipment should be equipped with sanding devices capable of applying sand to all rails in either direction of travel. 75.1403-7 Criteria - Mantrips The following shall be adopted as additional policy to govern the use of "scoop tractors" when transporting persons: October 2003 (Release V-34) 126
