Which control helps communicate hazards and define work areas?

• A. Training
• B. PPE
• C. Signs / Work Area
• D. Medical Removal

Answer: (C)

Communicating hazards and defining where work occurs is done most effectively with clear Signs and a defined Work Area. Posting appropriate signs alerts workers to specific hazards, required precautions, and restricted zones, while physical delineation of the work area creates visible boundaries that prevent confusion and unauthorized entry. This setup provides immediate, on-the-spot guidance that supports other controls, like training and PPE, by ensuring everyone knows where hazards exist and what protections are in place. Training explains hazards and procedures, and PPE protects individuals, but neither alone establishes on-site hazard communication and area boundaries. Medical removal is about moving workers with health concerns out of exposure, not about signaling hazards or demarcating zones.
