Question: 1 / 400

What should be done before repairing a compressor?

Close all windows in the area

Always turn off the compressor and shut down electrical supply

Before repairing a compressor, it is essential to always turn off the compressor and shut down the electrical supply. This action ensures safety for the personnel performing the repair work by eliminating the risk of accidental operation of the compressor during maintenance. Turning off the power prevents any electrical shocks or unintended activation that could lead to injury. Additionally, it allows the technician to conduct repairs without the worry of the equipment unexpectedly starting up.

While notifying personnel in the vicinity and draining oil are important safety measures in different contexts, they do not address the immediate safety needs linked to working with the electrical and mechanical components of the compressor. Closing windows might be useful for controlling environmental factors, but it does not provide the necessary safety measures needed prior to beginning repair work.
