SafetyQuestion 471 of 521
Standard electrical arc-flash PPE also includes head and hearing protection because:
a.Electrical arcs are silent and harmless to the ears
b.Hard hats are always optional for electricians
c.An arc blast produces intense heat, pressure, and sound, so a non-conductive (Class E) hard hat and hearing protection are required
d.Only the gloves matter during an arc event
Explanation
An arc blast releases extreme heat, a pressure wave, and very loud sound, so a Class E (electrical) hard hat and hearing protection are part of the PPE. Arcs are far from silent, hard hats are not optional in this work, and gloves alone do not address the head, hearing, and blast hazards.
