Answer:
Safety helmets protect against a range of hazards, including:
Falling objects: They provide a barrier against objects that may fall from above, such as tools, debris, or construction materials.
Impact: Safety helmets absorb and distribute the force of an impact, reducing the risk of skull fractures, concussions, or traumatic brain injuries.
Electrical hazards: Safety helmets with electrical insulation properties protect against electrical shocks or burns in environments where there is a risk of contact with live electrical wires or circuits.
