Performance under pressure: For your safety

Compressed air, like any form of energy, can be dangerous if it’s not properly controlled. Compressor experts offer the following safety tips to harness this energy safely:

• Make sure air compressors have safety valves to release excess pressure.

• Fittings and gauges should be metal, not plastic.

• Look for units with the UL, CSA or CETL marks. They designate that the model meets electrical and structural safety standards.

• Wheeled portable compressors can weigh 150 to 200 lbs. Move them carefully.

• Engines, mufflers and compressor units can get very hot if they run for extended periods. Avoid hot components to reduce the chance of burns.

• Never weld a leaking tank because the risk of injury is significant. Always replace a cracked or leaking tank instead of trying to repair it.

• Repair or replace damaged or rattling belt guards. They are there for a reason, so don’t remove them.

• Operate compressors on a level surface for proper lubrication of internal components. (However, some units can be operated at slight angles.)

• Make sure your compressor has an automatic thermal overload (ATO) that automatically shuts down the compressor if the motor becomes overloaded. Some ATO switches reset automatically, while others must be reset with a manual push-button.

• Don’t adjust pressure switches in an attempt to increase pressure. Compressors are designed to operate at their rated pressure, with safety factors matched to it. If you need more pressure, buy an air compressor with a higher rating.

• Don’t use extension cords with 120-volt compressors. Instead, use additional hose. This minimizes tripped circuit breakers and overheated electrical cords.

• Unplug the air source when a tool is not in use or when making adjustments.

• Read the safety information provided with the compressor.
