What is the standard safe threshold for current passing through a human body, exceeding which could be dangerous?

The standard safe threshold for current passing through a human body is generally recognized to be between 10 to 20 milliamps (mA). At this level, there is a risk of causing involuntary muscle contractions, which can hinder a person's ability to escape from the electrical source or maintain control over their body, potentially leading to more severe injuries or fatalities.

Current below this threshold is typically considered safe for a brief exposure, while exceeding it increases the risk of serious health impacts, including cardiac arrest, respiratory paralysis, and other harmful effects. It’s important to note that safety standards may vary slightly based on regulatory guidelines or specific circumstances but the 10-20 mA range is consistently identified as a critical threshold for electrical safety.
