This class of hard hats does not protect you from electrical shock.

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

Hard hats are rated for electrical protection, not just impact. Class C helmets are designed for impact protection only and are not rated to insulate against electrical shock. That means they won’t help if you come into contact with live electricity. For electrical work, you’d choose a helmet with electrical protection, such as Class A or Class B, which are rated to insulate up to specific voltage levels (Class A for lower voltages, Class B for higher voltages). The key idea is that Class C does not provide electrical insulation, so it won’t protect you from electric shock.
