SafetyQuestion 472 of 521
For electrical work, a hard hat should be:
a.Class C (conductive/vented) for better airflow
b.Class E, tested to protect against electrical contact up to 20,000 volts
c.Any bump cap will do
d.Class G only, tested to 1,000 volts
Explanation
Class E (electrical) hard hats are dielectrically tested to protect against contact up to about 20,000 volts, making them the correct choice for electrical work. Class C is conductive and unsafe near electricity, a bump cap offers little impact protection, and Class G (about 2,200V) provides far less electrical protection than Class E.
