What should storage areas have to warn workers about hazards?

• A. Fire alarms
• B. Security cameras
• C. Ventilation
• D. Warning signs

Answer: (D)

Warning signs provide a direct and visible way to communicate hazards in storage areas. They alert workers to what substances are present, the specific dangers (such as flammability, toxicity, or corrosivity), and often indicate required PPE or safe handling procedures. This kind of clear, at-a-glance information helps people act safely and supports regulatory requirements like OSHA’s Hazard Communication standards. Signs should be placed where they’ll be seen—at storage area entrances, on shelves or cabinets with hazardous materials, and on containers themselves—and be durable, legible, and use standard symbols.

Fire alarms are for indicating a fire emergency, not for conveying day-to-day hazard information. Security cameras monitor and record activity rather than warn workers about hazards. Ventilation improves air quality but doesn’t provide warnings or safety instructions.
