What is the minimum threshold for irreparable damage to body tissues due to electrical current?

The minimum threshold for irreparable damage to body tissues due to electrical current is often considered to be over a few amps. This is because the severity of electrical injury to tissues is largely dependent on the amount of current flowing through the body, measured in amperes (amps). The human body's response to electrical current can lead to various injuries, including burns, muscle damage, and disruption of the heart's electrical signals.

When the current exceeds this threshold, it can cause significant thermal and electrochemical effects within tissues. High currents, particularly those that reach the range of a few amps or more, can result in permanent damage to vital organs and systems, especially the heart and nervous system.

In contrast, lower levels of current, while still potentially dangerous, may not lead to immediate or irreparable damage, which is why the threshold has been set at a few amps. Understanding this threshold is crucial for safety and risk management concerning electrical hazards.
