§ 33.24. Falls and slides of material.

 (a)  No person shall drill, load, attach block chains to a lift, or do any work about a working face until such working face has been personally examined by the pit, quarry, or blaster foreman. If the working face is found unsafe, all hazards shall be removed by workmen under the personal supervision of the pit, quarry or blaster foreman, or other qualified person, before permitting other men to commence work.

 (b)  No person shall work at any point where he may be in danger from slides or falls of loose material without the presence of some person who shall be in position to help him should he fall or be injured.

 (c)  On all loading platforms, the mechanism for controlling the flow of material into cars, trucks or other vehicles shall be so located and constructed that the operator shall not be required to climb upon or stand on the sides of any car, truck or other vehicle being loaded. Installations which permit the operator to stand on the ground or on separate working platforms shall be accepted.
