Electrical circuits must be locked-out/tagged-out before electricians work on any equipment. Is this true or false?

The statement is true. Lockout/tagout (LOTO) procedures are critical to ensuring the safety of workers, particularly electricians, when they are working on electrical equipment or circuits. The purpose of these procedures is to prevent accidental energization or the release of hazardous energy during maintenance or repair work. By locking and tagging equipment, it effectively communicates that the equipment should not be operated until the tag is removed and the lock is taken off, thereby protecting workers from potential electrical shocks or injuries.

These practices are not only essential for high-voltage systems but apply to all electrical circuits where there is a risk of unexpected energization. Furthermore, lockout/tagout procedures are standard requirements outlined in OSHA regulations, which highlight the importance of preventing workplace injuries and ensuring that all safety measures are adhered to before work begins. Hence, the requirement for lockout/tagout applies universally across various types of electrical work, making this statement true.
