(b) Belt conveyor head pulleys, tail pulleys, single tension pulleys, dip take-up pulleys, chain conveyor head drums or sprockets and dip take-up drums and sprockets shall be guarded. The guard shall be such that a person cannot reach behind it and become caught in the nip point between the belt, chain, drum, pulley or sprocket.
Note: Normally, conveyor belt support rollers need not be guarded unless they create a potential hazard for serious injury.
(c) Crossovers as defined in Section 3207 of these Orders shall be provided where necessary, which will allow employees to pass over or cross a conveyor. Unless a 6-foot 6-inch headroom clearance is provided, employees shall not be permitted to pass under conveyors.
(d) Conveyors passing over areas that are occupied or used by employees shall be so guarded as to prevent the material transported from falling and causing injury to employees.
(e) Where employees pass under the return strands of chain conveyors a shallow trough or other effective means of sufficient strength to carry the weight of the broken chain shall be provided.
(f) Employees shall not be permitted to ride or walk on a moving power driven chain, belt or bucket.
(g) Conveyors using electrically released brakes shall be constructed so that the brakes cannot be released until power is applied and that the brakes are automatically engaged if the power fails or the operating control is returned to the stop position.
(h) Powered conveyors shall not be started until all exposed employees are clear of the conveyor or have been warned that the conveyor is about to start.
