Question

which of the following must ppe for your head do? select all that apply
absorb the impact of blows to the head
serve as insulators against electrical shock
serve as insulators against cold weather
keep you cool in high temperatures
be water resistant and slow-burning
shield the scalp, face, neck, and shoulders

Explanation:

To determine what a hard hat must do, we analyze each option:

• "Absorb the impact of blows to the head": Hard hats are designed to protect from head impacts, so this is correct.
• "Serve as insulators against electrical shock": Hard hats (especially Class E or G) insulate against electrical shock, so this is correct.
• "Serve as insulators against cold weather": Hard hats aren’t primarily for cold insulation (winter liners can be added, but it's not a core function).
• "Keep you cool in high temperatures": Ventilated hard hats help with heat, but it's not a "must - do" core safety function like impact/electrical protection.
• "Be water resistant and slow - burning": Hard hats are often water - resistant and made of slow - burning materials for safety, so this is correct.
• "Shield the scalp, face, neck, and shoulders": Hard hats mainly protect the head; face/neck/shoulders are not their primary shield area.

So the correct options are:

• Absorb the impact of blows to the head
• Serve as insulators against electrical shock
• Be water resistant and slow - burning

Answer:

• Absorb the impact of blows to the head
• Serve as insulators against electrical shock
• Be water resistant and slow - burning
