Air tools offer a great way to increase productivity on the job-site. Jack hammers impact wrenches, chipping hammers and nail guns are common air tools on many job sites. Commonly used air tools create risk and must be used properly.
Working with Air Tools
- Never discharge an airline towards another worker.
- Treat all tools as loaded while they are connected to an airline.
- Never use a tool that is missing a guard or safety feature.
- Always wear proper PPE when using the tool. 100% eye protection.
- Remove from service and “red tag” defective tools.
- Disconnect the tool from the compressed air supply and bleed off excess air before repairs are done. This should include turning off the air at the source at all connections.
- Tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected.
- Air hoses with inside diameters greater than ½ inch must have safety devices to reduce pressure.
- Always consult the tool manufacturer for additional safety concerns.
- Never lower a hose by use of the air line.
- Never use compressed air to clean yourself off
If it is necessary to use compressed air for cleaning, always reduce the pressure to 30 psi or less and proper chip guarding.
