When is electricity dangerous?

Current as low as 9 milliamps (a milliamp is a thousandth of an amp) can produce a painful shock. For reference, consider that the standard household circuit operates at 15 amps, and you should see that most electrical circuits in your work area or home should be treated with respect! Current as low as 100 milliamps can be fatal! The voltage threshold for alternating current is 50 volts, and 100 volts for direct current. If these thresholds are met or exceeded, several hazard controls must be implemented.
