What is the function of barriers in egress safety?

• A. To direct movement, restrict entry into hazardous zones, and keep exits clear.
• B. To prevent people from using any exit.
• C. To hold equipment in place during evacuation.
• D. To absorb blast energy.

Answer: (A)

Barriers in egress safety are meant to guide people along approved paths, prevent entry into hazardous areas during an evacuation, and keep the exits themselves clear for a quick, unobstructed exit. This helps create an orderly flow so occupants can leave safely and responders can reach the area if needed.

Any option suggesting barriers prevent using an exit entirely misses the purpose, since the goal is to keep exits accessible. Saying barriers hold equipment in place or absorb blast energy refers to other safety roles, not the primary function of directing movement, restricting access to hazards, and keeping exits open for evacuation.
