According to ANSI standards, what voltage rating must hard hats meet?

The correct voltage rating that hard hats must meet, according to ANSI standards, is 20,000 volts. This standard ensures that hard hats designed for electrical work provide adequate insulation against electrical hazards. Hard hats must be tested to withstand this voltage to protect the wearer from electric shock that can occur while working in environments where electrical exposure is possible. Meeting the 20,000-volt requirement helps ensure that the hard hat provides an adequate safety margin for electrical insulation, making it suitable for workers who may be exposed to high voltages.

The other options reflect lower voltage ratings, which do not meet the specific insulation requirements outlined in the ANSI standards for hard hats used in high-risk electrical environments.
