When performing electrical repairs, what is the first step a maintenance worker should take?

When performing electrical repairs, the first step a maintenance worker should take is to turn off the power supply. This action is crucial for several reasons. Primarily, turning off the power reduces the risk of electrical shock, which can occur when a worker comes into contact with live wires or components. Ensuring that the power is off allows the maintenance worker to perform their tasks safely without the hazard of being electrocuted or causing inadvertent damage.

After the power has been turned off, it becomes appropriate to check for electrical malfunctions, use tools to replace damaged wires, or consult with a supervisor as necessary. However, these steps should only be taken after ensuring that the work area is safe, highlighting the importance of prioritizing safety in electrical repair work.
