Article 10 - Haulage and Earth Moving
Section 1593 - Haulage Vehicle Operation

(a) Vehicles shall not be operated at speeds which will endanger the driver or traffic.

(b) Haulage vehicles shall be under positive control during all periods of operation. When descending grades, the vehicles shall be kept in gear.

(c) When wire rope is being wound on a power-driven drum, a mechanical threading device shall be used, where practicable, to guide the cable. When this operation must be done manually, the feet shall not be used and the hands shall be kept at least 3 feet from the drum.

(d) All vehicles in use shall be checked at the beginning of each shift to assure that the following parts, equipment, and accessories are in safe operating condition and free of apparent damage that could cause failure while in use: service brakes, including trailer brake connections; parking system (hand brake); emergency stopping system (brake); tires; horn; steering mechanism; coupling devices; seat belts; operating controls; and safety devices. All defects affecting safe operation shall be corrected before the vehicle is placed in service. These requirements also apply to equipment such as lights, reflectors, windshield wipers, defrosters, fire extinguishers, etc., where such equipment is necessary.

(e) Exhaust Gases. Vehicle engines shall not be allowed to run in closed garages or other enclosed places, unless vents are provided which effectively remove the exhaust gases from the building.

(f) Securing Loads. Loads on vehicles shall be secured against displacement.

(g) Tire Repair. Except for emergency field repairs, a safety tire rack, cage, or equivalent protection shall be used when inflating truck or equipment tires after mounting on a rim, if such tires depend upon a locking ring or similar device to hold them on the rim.

(h) Parking Brakes. Whenever the equipment is parked, the parking brake shall be set. Equipment parked on inclines shall have the wheels chocked and the parking brake set or be otherwise prevented from moving by effective mechanical means.

(i) Scissor points on all front-end loaders which constitute a hazard to the operator shall be adequately guarded.

(j) A loader shall not travel without adequate visibility for the driver and stability of the equipment.

(k) No loading device shall be left unattended until the load or bucket is lowered to the ground, unless proper precautions such as blocking are taken to prevent accidental lowering.

(l) All high lift trucks (e.g., fork lifts), industrial trucks, and rider trucks used on a construction site shall conform with the applicable orders in Article 25 of the General Industry Safety Orders and:

(m) Loading buckets, scoops, blades or similar attachments on haulage vehicles which do not provide fall protection equivalent to that required by Section 3210 of the General Industry Safety Orders or Article 24 of the Construction Safety Orders (starting with Section 1669) shall not be used as work platforms or to elevate or transport employees except as provided by Section 1597 of these Orders.

(n) The use, care and maintenance of slings used in lifting suspended loads with excavators, loaders and similar equipment shall comply with the requirements of Article 101 of the General Industry Safety Orders.
