What current range is associated with extreme pain, respiratory arrest, and possible death?

The current range associated with extreme pain, respiratory arrest, and possible death is typically above 50 milliamperes. At this level, the physiological effects on the human body become significantly severe.

When electrical current passes through the body, even small amounts can cause pain, but as the current increases, the risk of severe injury and fatality rises sharply. Currents in the range of 51 to 100 milliamperes are known to cause severe muscle contractions, making it difficult to let go of the source of the current, leading to prolonged exposure and increased danger. Furthermore, at this range, individuals can experience significant cardiac disturbances, respiratory paralysis, and may even enter a state of unconsciousness.

This makes currents in this range particularly dangerous and potentially lethal, as they can quickly lead to situations of extreme pain and physiological distress. Understanding these thresholds is critical for assessing hazards in electrical environments and ensuring safety measures are in place to prevent accidental exposure to these dangerous current levels.
