When should electrical equipment be worked on?

Working on electrical equipment should always be done after someone has inspected and tested it to ensure that the equipment is safe and functioning properly. This practice is crucial for several reasons. First, inspection and testing help identify any existing issues or hazards that could pose a risk to personnel or disrupt the operation of the equipment.

Additionally, thorough inspection and testing protocols are often part of regulatory compliance and safety standards, which are designed to protect workers from injuries such as electric shock or burns. It ensures that the equipment is in compliance with necessary safety standards before proceeding with any repairs or maintenance.

By conducting these checks, workers can ascertain that equipment is not only safe to use but also reduces the likelihood of unforeseen complications arising during maintenance. This reduces downtime and enhances overall safety in the workplace.

In contrast, the other options imply inappropriate conditions for working on electrical equipment. For example, working on new equipment without prior inspection could overlook potential defects, and waiting for a supervisor may cause delays in urgent repairs and maintenance. Lastly, attending to equipment before a routine maintenance check without prior testing might overlook vital safety assessments necessary to avoid risks and hazards.
