What is one of the most crucial rules when working with electrical equipment?

The principle that electrical equipment should be treated as energized until it has been verified otherwise is fundamental in preventing electrocution hazards. This rule emphasizes the importance of caution and vigilance when working around or with electrical systems.

In a healthcare setting, where patients may depend on electrical devices, it becomes crucial to ensure that equipment is safely de-energized before any maintenance or handling takes place. This approach helps to safeguard healthcare professionals against the risk of accidental shock, which could occur if equipment is mistakenly assumed to be safe.

Verification of de-energization typically involves using appropriate testing equipment to confirm that no voltage is present. This practice not only helps protect the individual working on the equipment but also enhances overall safety in the healthcare environment by preventing potential hazards from fully operational devices. Understanding this crucial rule is essential in maintaining a safe working atmosphere and preventing serious accidents related to electrical use in healthcare settings.
