What should a compressor operator do when checking for leaks?

When checking for leaks, a compressor operator should employ both auditory and visual methods to identify potential air loss. This approach is essential because some leaks may not produce visible signs but can be detected through sound. For example, a hissing or escaping air noise may indicate a leak in the compressor’s fittings or hoses.

Furthermore, relying solely on visible signs could lead to missed leaks that are not immediately apparent. By actively listening for sounds indicative of leaks while also observing for signs such as frost buildup, moisture, or air movement, the operator can ensure a more thorough and effective check. This comprehensive method enhances safety, efficiency, and the overall functionality of the compressor system.

The other options do not adequately address the importance of a dual approach in detecting leaks, which is vital for ensuring proper maintenance and operation of the compressor.
