501 - Compressed Air, Pneumatic and Hydraulic Tools
NOTE: This paragraph does not apply to compressed breathing air hoses.
- Eye protection and other necessary PPE shall be worn when using compressed air equipment.
- Air/fluid hoses, hose connections, and hydraulic and pneumatic tools shall be visually inspected before each use.
- Pneumatic and hydraulic tools, including
hydraulic jacks, shall be operated per the manufacturer’s instructions.
NOTE: All pneumatic and hydraulic tools, including hydraulic jacks, shall be secured to prevent kicking out or becoming a flying object. - Air/fluid hoses shall be routed without posing a tripping hazard.
- All hoses must have a safety chain or pin to prevent the sections from coming apart under pressure. Additionally, hose sections shall be secured by lanyards, chains, whip restraints, or other appropriate devices.
- Twist-type fittings shall have securing mechanism attached to one side of the fitting at a minimum.
- Air hose couplings, such as Chicago fittings, shall be attached to the hose by use of crimped bands or other approved methods. Water hose clamps shall not be used.
- Compressed air shall not be directed at any part of the body or at any other person.
- Compressed air shall not be used for cleaning purposes except where reduced to less than 30 psi. If a 3- feet air lance is used, air pressures above 30 psi are permitted.
- The airflow shall not be stopped by kinking the hose. Airflow shall be controlled by valves.
- Before adjusting or changing air tools that are not equipped with quick-change connectors, the air supply valve shall be closed at the source. The hose shall be bled at the tool before breaking the connection.
- Safe operating pressures for tools, hoses, and valves shall not be exceeded. Pneumatic rotating tools shall be speed tested when maintenance or repair work is performed on the tools.
- Pneumatic power tools shall be secured to the air supply hose by a self-locking or other positive means to prevent the tool from being incidentally disconnected.
- A tool retainer shall be used, where provided, on pneumatic impact tools to prevent attachments from being incidentally ejected.
- Pneumatic power-operated hand tools supplied by air hoses exceeding ½-in. inside diameter shall have a safety device at the source of supply or branch line to shutoff or reduce pressure in the event of hose failure.
