Section 39.29. Conveyors, hand and automotive vehicles

(a) Defective wheels. Vehicles with wheels or other parts that are broken, cracked, or otherwise defective should be removed from service until the defective parts have been repaired or replaced with parts free from defects.

(b) Wheel mounting. Whenever practical, the wheels of vehicles should be mounted on axles inside the frame of the vehicle or inside the bearing which attaches them to the vehicle.

(c) Hand trucks. Two-wheeled handtrucks should always be parked in a vertical position at racks which will prevent them from falling over or in a horizontal position at locations not used for travelways. Truck handles should not be left extended on the floor. Whenever the construction permits, they should be secured in an upright position by means of springs, weights or retaining hooks or latches.

(d) Suspended loads. The practice of working under suspended vehicles supported only by a light chain, rope or single block should not be permitted. Working or walking under any suspended load should also not be permitted.

(e) Magnets. Working or walking under a load suspended by an electric magnet is prohibited pursuant to the provisions of Chapter 25, Subchapter B (relating to cranes, booms and hoists).

(f) Counterweights. Where the possibility of contact with persons exists, all counterweights shall be enclosed sufficiently to prevent fouling or striking persons.

(g) Blocking. All trucks or other vehicles being loaded should be properly chocked or blocked if there is a possibility of the vehicle moving by gravity or from jars.

(h) Securing loads. All loads not fully contained or supported by the vehicle carrying them should be secured to the vehicle by chains, cables, ropes, blocks, chocks or other effective devices.

(i) Runways or ramps. Runways or ramps on which wheelbarrows and handtrucks are operated should be so constructed that the wheels run on solid boards and not on cracks between boards. Workmen should not be permitted or required to operate wheelbarrows or handtrucks over runways or ramps which have the entire surface cleated to prevent slipping. Sufficient smooth space should be left for the passage of the wheels.

(j) Exhaust from engines. Internal combustion engines should not be started or permitted to run in spaces which are not thoroughly ventilated unless the exhaust is piped to the outside air.

(k) Filling procedure. When filling the tank of any internal combustion engine, the nozzle of the hose should always be kept in direct contact with the tank being filled, and the engine should be stopped during the operation.

(l) Walking on conveyors. All persons should be forbidden to ride or walk on mechanical or gravity conveyors at any time, except that workmen engaged in repairing such conveyors should be permitted to mount them in the performance of their work if such conveyors are stopped. Separate oiling platforms should be required at all points requiring lubrication.
