What is the first step to take before beginning any electrical work?

The first step to take before beginning any electrical work is to turn off and lock out power to the circuit. This critical safety measure ensures that there is no electrical current flowing to the work area, significantly reducing the risk of electrical shock or injury while working on the system.

Locking out the power means physically disabling the circuit's power source and securing it to prevent anyone from inadvertently turning it back on while work is being conducted. This practice is part of the lockout/tagout (LOTO) safety procedure, which is designed to protect workers from unexpected energization of equipment.

Prior to doing any electrical tasks, ensuring the circuit is de-energized not only safeguards the technician but also promotes a safe working environment for anyone nearby. While having tools ready, checking for circuit efficiency, and gathering necessary permits are also important steps in the electrical work process, they should come after securing the work area by turning off and locking out power.
