When working on energized equipment, what is a good practice to perform?

Keeping one hand in your pocket or behind your back is a recommended practice when working on energized equipment because it significantly reduces the risk of electrical shock. By maintaining one hand in a position that limits the pathway for current to flow through the body, you minimize the chance of becoming part of an electrical circuit. This principle is based on the understanding that if there is an accidental contact with a live part, the electrical current is less likely to travel through the heart, which can be fatal.

This approach is especially critical in environments where one might be exposed to high voltage or energized components, as it adds an additional layer of safety by preventing scenarios where both hands are in contact with conductive surfaces. It is a preventive measure to avoid serious injuries or fatalities that can occur from electrical accidents.

In comparison, marking equipment with warnings, relying on safety observers, or bypassing safety interlocks does not provide the same level of individual safety and could potentially lead to hazardous situations if not managed correctly.
