What is the maximum current level that should flow through a worker to ensure safety?

The maximum current level that should flow through a worker to ensure safety is often accepted at 10 mA. At this level, the majority of individuals will experience a tingling sensation, but it is generally considered below the threshold that can cause significant harm or increase the risk of muscular incapacitation or cardiac arrest.

While currents higher than this can pose serious risks, such as loss of control of muscular movement or potential electrical shock hazards, 10 mA is a reliable guideline for maximum safe exposure in many safety standards. This threshold is often cited in safety regulations to minimize the risks associated with electrical shock.

The selection of 10 mA underscores the importance of adhering to safety standards in environments where workers may be exposed to electrical currents, thereby preventing accidents and ensuring a safer working environment.
