What is the "Can't Let Go" range of current flow?

The "Can't Let Go" range refers to a specific range of electrical current flow that can lead to a sustained muscular contraction, making it difficult for a person to release grip on an object or release their hold in the presence of a dangerous electrical current. This range is recognized as generally spanning from 9 to 25 mA.

Currents within this range can significantly impact a person's neuromuscular function, causing involuntary muscle contractions. Understanding this range is vital for safety and risk assessment in electrical work, as being exposed to such currents can lead to serious injury or even fatalities due to prolonged muscle contractions or inability to let go when under electrical strain.

Choosing the correct range of current flow is crucial for those working with or around electricity and illustrates the importance of safety standards and awareness in these environments.
