What is the perception level of body current that should protect a male worker?

The correct choice for the perception level of body current that should protect a male worker is 1.1 mA. This is significant in ensuring safety standards are maintained when working with electrical systems.

The perception level is the amount of current that is felt by a person, which is essential for understanding thresholds that could lead to physiological effects or a potential hazard. A current level of 1.1 mA is recognized in industry standards as approximately the threshold at which a person can perceive an electrical shock. This specific value helps establish safety guidelines that dictate the maximum allowable current that can flow through a worker's body without causing harmful sensations or reactions.

Establishing this threshold is critical in designing protective measures and ensuring that safety protocols are effective in preventing electrical injuries in the workplace.
