According to 29 CFR 1926.95, which type of hard hat is required for electrical work involving exposure to high voltage?
Correct Answer
B) Type II, Class E
Class E hard hats are designed for electrical work and provide protection against high voltage electrical shock up to 20,000 volts. Type II provides additional protection from lateral impacts.
Why This Is the Correct Answer
Type II, Class E hard hats are specifically required for electrical work involving high voltage exposure. Class E (Electrical) hard hats are tested and rated to protect against electrical shock up to 20,000 volts. Type II designation provides additional protection from lateral impacts, which is important in electrical work environments where workers may be struck from the side. This combination ensures maximum protection for electrical workers exposed to high voltage hazards.
Why the Other Options Are Wrong
Option A: Type I, Class G
Type I, Class G only provides protection up to 2,200 volts, which is insufficient for high voltage electrical work that requires protection up to 20,000 volts.
Option C: Type I, Class C
Type I, Class C hard hats provide no electrical protection whatsoever - they are actually conductive and would increase electrical hazards rather than protect against them.
Option D: Type II, Class G
Type II, Class G only provides protection up to 2,200 volts, which is inadequate for high voltage electrical work requiring 20,000 volt protection.
Memory Technique
Remember 'E for Electrical' and 'Type II for high voltage' - think 'Extra protection for Electrical work needs Type II, Class E'
