Question 2

A Class E hard hat is rated to protect against electrical exposure up to what voltage?

Accepted Answer

30,000 volts

Answer

Class E (Electrical) hard hats are tested and rated to protect against electrical shock up to 20,000 volts phase-to-ground, with a 30,000-volt dielectric strength test.

Question 3

When must a hard hat be removed from service and replaced immediately?

Accepted Answer

After any impact, even if no visible damage is present

Answer

Hard hats must be replaced after sustaining any impact because internal structural damage may not be visible, yet the protective capability is compromised.

Question 4

Which type of eye protection provides the best defense against both impact hazards and chemical splash on a tower work site?

Accepted Answer

Chemical splash goggles

Answer

Chemical splash goggles provide a sealed barrier around the eyes, protecting against both impact hazards and liquid splash that safety glasses with side shields cannot fully prevent.

Question 5
