Which of the following is considered a critical safety practice in electrical work?

Lockout/tagout procedures are crucial in electrical work as they ensure that machinery and electrical systems are properly shut off and cannot be started again until maintenance or repairs are completed. This safety practice protects workers from unexpected energization or the release of stored energy during service or maintenance activities. By using lockout/tagout, workers can prevent accidents and injuries that could arise from machines or circuits being inadvertently activated.

The importance of this procedure is highlighted by the potential hazards associated with electrical work. Without utilizing lockout/tagout, a worker could be exposed to live circuits or moving parts that could cause severe injuries or even fatalities.

In contrast, ignoring abnormal sounds, using tools without insulation, and performing repairs during storms significantly increase the risk of electrical accidents and should be avoided in safe electrical practices. These actions do not prioritize safety and can lead to dangerous situations, highlighting the necessity of adhering to protocols like lockout/tagout to maintain a safe working environment.
