What protective equipment must employees wear in areas where there is a danger of head injury?

In environments where there is a risk of head injury, the use of helmets is essential for ensuring the safety of employees. Helmets are specifically designed to absorb impact and protect the skull and brain from injuries caused by falling objects, bumps, or other hazards that could lead to head trauma. When working in construction, maintenance, or other industrial settings, the likelihood of accidents increases, making the use of helmets a critical safety measure.

The other options, while important in their own right, do not provide the necessary protection against head injuries. Gloves protect the hands, safety goggles shield the eyes, and earplugs guard against hearing damage. However, none of these alternatives address the specific risk to the head, which is what helmets are designed to mitigate. Therefore, helmets are the appropriate and required protective equipment in situations where head injury risks are present.
