Which of the following is an important safety measure during a power failure?
During a power failure, one of the most critical safety measures is to switch off all machines and electrical equipment. This prevents unexpected hazards when the power supply is suddenly restored.

For example, rotating machines or cutting tools may start without warning, posing serious risks to nearby workers.
