Where must hard hats be worn?

• A. Only in the control room.
• B. Only outdoors.
• C. Not required in any area.
• D. Everywhere on site except inside administrative buildings.

Answer: (D)

Head protection is needed wherever there’s a risk of head injury from falling objects, overhead hazards, or moving equipment. On a plant site, hazards aren’t limited to inside buildings; outdoor work zones, loading areas, maintenance under cranes, and any place where materials are handled can pose risks to the head. Wearing a hard hat across the site ensures you’re protected as you move between areas. Administrative buildings are treated as lower-risk spaces, so the policy typically allows removal of the hard hat there, while you’d put it back on when you re-enter production or outdoor areas. That’s why this option is the best: you must wear a hard hat everywhere on site except inside administrative buildings.
