What should a maintenance worker do before starting any job involving electrical work?

Before starting any job involving electrical work, a maintenance worker should prioritize safety by turning off the power supply and testing the circuit. This action is crucial because it eliminates the risk of electric shock and ensures that the circuit is indeed de-energized. Once the power is turned off, testing with a proper voltage tester confirms there is no current flowing, providing an additional layer of safety before proceeding with any repairs or modifications.

Ensuring the power is off and the circuit is safe to work on is a fundamental practice outlined in safety protocols and regulations, making it essential for preventing accidents and ensuring the well-being of the worker and anyone nearby. This proactive measure establishes a safe working environment, which is the cornerstone of electrical maintenance work.
