| Definition |
An air compressor is a mechanical device that increases the pressure of the air inside a tank by reducing its volume, by this storing potential energy. This energy is converted into fast and powerful mechanical work when the pressure is released, allowing it to actuate pneumatic tools. |
| Hazards
This list of potential hazards is not comprehensive. Workers are required to complete a Hazard Assessment prior to starting this task to ensure all hazards are identified and controlled.
|
Chemical:
- Carbon monoxide (gas powered)
Physical:
- Rupture under excessive pressure can cause potential explosions
- Dislodge particles can enter eyes and abrade skin
- Air embolism (air bubbles in blood)
- Noise
- Tank rupture/explosion
- Eye/skin injury
- Slips/Trips
|
| Controls |
Engineering:
Administrative:
- Manufacturers’ Specifications
Personal Protective Equipment:
- Task-Specific PPE: Hearing and eye protection
|
| Work Site Supervisory Responsibility |
Do
- Ensure Personal Protective Equipment (PPE) is being worn.
- Ensure Safe Work Practice (Contractor) and Safe Job Procedure (Employee) are followed.
- Coach Workers on SWP for the use of compressed air
- Ensure air compressors are equipped with pressure relief valves and guards.
Do not
- Allow Workers to use damaged equipment.
- Allow Workers to use gas compressors in enclosed spaces.
- Allow Workers to point pneumatic tool at themselves or others.
|
| Worker Responsibility |
Do
- Inspect compressor, hoses, and tools for damage before each use
- Wear all required PPE: eye protection, hearing protection, steel toed boots.
- Keep hoses clear of walkways and work areas to prevent tripping hazards
- Properly drain moisture from the air receiver tank at the end of each day to prevent rust and corrosion
- Keep hoses away from sharp edges, heat sources, and pinch points.
- Electrical compressor connections must be three-pronged ground or double insulated.
- Disconnect the tool from the power source when making adjustments or changing attachments.
- Keep hands, hair, loose clothing or dangling jewelry clear or all moving parts when operating.
- Remove cords from receptacles by the plug, not the cord
Do not
- Use compressed air to clean your body or clothes.
- Point pneumatic tools at yourself or others for any reason, including to clean clothing, skin, or hair.
- Carry pneumatic tools by the hose.
- Exceed the manufacturer’s recommended air pressure for the tool.
- Leave a compressor running unattended.
- Attempt to kink or tie hoses to stop airflow.
- Use undamaged, cracked, or oil-soaked hoses.
- Run gas compressors in enclosed areas.
- Modify, tampered with or removed safety guards and devices.
