Compressed Air 29 CFR

Because compressed air is supplied by a compressor, great care must be taken to ensure that certain types of equipment are operating in a safe manner. Safety

Safety chains or other suitable locking devices must be used at couplings of high-pressure hose lines where a connection failure would create a hazard. Before 

When compressed air is used with abrasive blast cleaning equipment, the operating valve must be held open manually. As compressed air is used to inflate auto tires, a clip-on chuck and an inline regulator preset to 40 psi are required. It should be prohibited to use compressed air to clean up or move combustible dust because such action could cause the dust to be suspended in the air and cause a fire or explosion hazard. 

Cylinders containing liquefied fuel gas should be stored or transported in a position so that the safety relief device is always in direct contact with the vapor space in the cylinder. All valves must be closed off before a cylinder is moved, when the cylinder is empty, and at the completion of each job. Low-pressure fuel-gas cylinders should be checked periodically for corrosion, general distortion, cracks, or any other defect that might indicate a weakness or render it unfit for service.
