An important occupational safety and health administration (OSHA) regulation deals with

• A. Hazardous Chemicals
• B. Fire Safety
• C. Unlocked Exit Doors
• D. Noise Levels

Answer: (C)

OSHA emphasizes life-safety in the way exits are used. The key idea is that exit doors must be readily operable from the inside and not locked in a way that blocks egress during an emergency. When doors can be opened easily without a key or special knowledge, people can exit quickly, which reduces the risk of injuries or fatalities in fires or other urgent situations. Regulations often require mechanisms like push bars or other panic hardware and prohibit locking exit doors in a way that prevents immediate use.

While proper handling of hazardous chemicals and general fire safety are important OSHA topics, they address different aspects of workplace safety. Noise level regulations aim to prevent hearing damage, and chemical safety standards focus on labeling and handling hazards. The specific requirement that makes the most difference for quick, safe evacuation is keeping exit doors unlocked and operable.
