Air compressor safety tips
Air compressors find their way onto many jobsites. Make sure you keep your site safe when the compressors are being used. There are other safety regulations that you and your crew should follow, but these tips are a good start at making sure you’re covering the basics:
- Wear ear plugs.
- Compressed air pipelines should be identified (psi) as to maximum working pressure.
- Air supply shutoff valves should be located (as near as possible) at the point of operation.
- Air hoses should be kept free of grease and oil to reduce the possibility of deterioration.
- When possible, air supply hoses should be suspended overhead to prevent trips and falls.
- Secure hose ends to prevent whipping if an accidental cut or break occurs.
- Pneumatic impact tools, such as riveting guns, should never be pointed at a person.
- Before a pneumatic tool is disconnected (unless it has quick-disconnect plugs), the air supply must be turned off at the control valve and the tool bled.
- Never use compressed air to clean dirt and dust from clothing or a person. (Shop air used for cleaning should be regulated to 15 psi unless equipped with diffuser nozzles.)
- Goggles, face shields or other eye protection must be worn by personnel using compressed air for cleaning equipment.
- Static electricity can be generated through the use of pneumatic tools. This type of equipment must be grounded or bonded if it is used where fuel, flammable vapors or explosive atmospheres are present.
Air Distribution Lines
- The lines should be made of high-quality materials, fitted with secure connections.
- Use only standard fittings.
- Avoid bending or kinking air hoses.
- Make sure hoses are properly connected to pipe outlets before use.
- Inspect lines frequently for defects and make any needed repairs immediately.
Pressure Regulation Devices
- Only qualified personnel should be allowed to repair or adjust pressure regulating equipment.
- Install regulating devices on compressor equipment in such a way that the safeguards cannot be made inoperative.
- Air tank safety valves should be set no less than 15 psi or 10 percent (whichever is greater) above the pressure of the compressor (but never higher than the maximum allowable working pressure of the air receiver).
- Air lines between the compressor and receiver should usually not be equipped with stop valves. Where stop valves are necessary and authorized, ASME safety valves should be installed between the stop valves and the compressor.
- The safety valves should be set to blow at pressures slightly above those necessary to pop the receiver safety valves.
- Blow-off valves should be located on the equipment and shielded so sudden blow-offs will not cause injuries or damage.
- Safety valves exposed to freezing temperatures should be located so water cannot collect in the valves. Frozen valves must be thawed and drained before operating the compressor.
- Air compressor equipment should be operated only by authorized and trained personnel.
- intake should be from a clean, outside, fresh air source.
- Screens or filters can be used to clean the air.
- Air compressors should never be operated at speeds faster than the manufacturer’s recommendation.
- Moving parts—such as compressor flywheels, pulleys, and belts that could be hazardous—should be effectively guarded.
