What is the current level that may result in cardiac arrest or death?

The specified level that may result in cardiac arrest or death is 10,000 mA (milliamps). At this level of electrical current, the risk of serious physiological effects increases significantly. Typically, currents as low as 100 mA can lead to lethal arrhythmias if they pass through the heart, and 10,000 mA is well above this threshold, thus posing a substantial risk for severe injury or fatality.

In general, higher levels of electrical current lead to greater danger due to the possibility of disrupting the normal electrical signals of the heart. It’s important to recognize that while various currents have different thresholds for causing harm, 10,000 mA is known to be a critical point at which the risk escalates dramatically, potentially leading to cardiac arrest. This knowledge is vital for understanding both safety measures in environments with electrical hazards and the physiological impacts of electrical exposure on the human body.
