805 KAR 3:100. Equipment use and operation.

      RELATES TO: KRS 351.070

      STATUTORY AUTHORITY: KRS 351.070

      NECESSITY, FUNCTION, AND CONFORMITY: This administrative regulation is to establish safety standards controlling the use of equipment and the operation thereof in the Commonwealth's surface type coal and clay mines which include strip and auger mining operations.

      Section 1. Use of Equipment Guards. (1) Gears; sprockets; chains; drive, head, tail and take-up pulleys; flywheels; couplings; shafts; sawblades; fan inlets; and similar exposed moving machine parts which may cause injury to persons, shall be guarded.

      (2) Overhead belts shall be guarded if the whipping action from a broken belt would be hazardous to persons below.

      (3) Guards at conveyor drive, head and tail pulleys shall be sufficient to prevent a person from reaching behind the guard and becoming caught between the belt and the pulley.

      (4) Protruding set screws on revolving parts shall be guarded.

      (5) Except when testing the machinery, guards shall be securely in place while machinery is being operated.

      (6) Guards shall be sufficiently strong and maintained to provide the required protection.

      (7) Stationary grinding machines other than special bit grinders shall be equipped wit;

      (a) Peripheral hoods (less than ninety (90) degree throat openings) capable of withstanding the force of a bursting wheel;

      (b) Adjustable tool rests set as close as practical to the wheel;

      (c) Safety washers.

      (8) Face shields or goggles, in good condition, shall be worn when operating a grinding wheel.

      (9) Hand-held power tools, other than rock drills, shall be equipped with controls requiring constant hand or finger pressure to operate the tools or shall be equipped with friction or other equivalent safety devices.

      (10) Guards or shields shall be provided in areas where flying or falling materials present a hazard.

      (11) Vehicles such as fork lifts, trucks, front-end loaders, and bulldozers shall be provided with rollbar protection when necessary to protect the operator.

      (12) Fork lift trucks, front-end loaders, and bulldozers, shall be provided with substantial canopies when necessary to protect the operator against falling material.

      (13) Unsafe equipment or machinery shall be removed from service immediately.

      (14) Machinery and equipment shall be operated only by authorized and experienced persons.

      (15) Repairs or maintenance shall not be performed on machinery until the power is off and the machinery is blocked against motion, except where machinery motion is necessary to make adjustments or where nonenergized components of large machinery can be safely repaired while the machine is operating.

      (16) Men shall not work on mobile equipment in a raised position until it has been blocked in place securely. This does not preclude the use of equipment specifically designed, such as elevated mobile work platforms.

      (17) Drive belts shall not be shifted while in motion unless the machines are provided with mechanical shifters.

      (18) Belts, chains, and ropes shall not be guided onto power-driven moving pulleys, sprockets, or drums with the hands except on slow moving equipment especially designed or hand feeding.

      (19) Pulleys or conveyors shall not be cleaned manually while the conveyor is in motion.

      (20) Belt dressings shall not be applied manually while belts are in motion unless an aerosol-type dressing is used.

      (21) Machinery shall not be lubricated while in motion where a hazard exists unless equipped with extended fittings or cups. (SMS-9; 1 Ky.R. 853; eff. 5-14-75.)
