A. The following items of shop and other equipment shall be guarded and maintained adequately:
1. Any gear, sprocket, pulley, fan blade or propeller, or friction device or coupling that has a protruding bolt or nut;
2. Shafting or any projecting shaft end that is within seven feet of the floor or platform level;
3. Any belt, chain, or rope drive that is within seven feet of the floor or platform;
4. Any fly wheel. A fly wheel extending more than seven feet above the floor shall be guarded to a height of at least seven feet;
B. No machinery shall be repaired or serviced while the machinery is in motion; however, this prohibition shall not apply where a safe remote device is used.
C. Any guard or safety device that has been removed from any machine shall be replaced before the machine is put in operation.
D. Each mechanically operated grinding wheel shall be equipped with (i) safety washers and tool rests; (ii) substantial retaining hoods, the hood opening of which shall not expose more than a 90-degree sector of the wheel; and (iii) eyeshields, unless goggles are worn by the miners. Each retaining hood shall include either a device to control and collect excess rock, metal, or dust particles or a device providing equivalent protection to the miner operating such machinery.
E. The operator or his agent shall develop procedures for examining for potential hazards, completing proper maintenance, and properly operating each type of centrifugal pump. Such procedures shall, at a minimum, address the manufacturer’s recommendations for start-up and shutdown of the pump, proper actions to be taken when a pump is suspected of overheating, the safe location of start and stop switches, and actions to be taken when a sign of structural metal fatigue, such as a crack in the frame, a damaged cover mounting bracket, or a missing bolt or other component is detected. Every miner who repairs, maintains, or operates any type of centrifugal pump shall be trained in these procedures.
