The physiological effects of electric shock depend directly on current magnitude, frequency, and duration. IEEE Std 80-2013 builds its safety criteria on the seminal research of Charles Dalziel, which establishes the thresholds for ventricular fibrillation—the primary cause of death from electrical shock.
Personnel Safety: It limits step and touch voltages to safe levels, preventing fatal electric shocks to workers and the public.
