• B. To direct foot traffic during emergencies
• C. To contain smoke during a fire event
• D. To support structural components

Answer: (C)

The primary purpose of smoke barriers in a commercial building is to contain smoke during a fire event. Smoke barriers are designed to restrict the movement of smoke through a building, which is crucial because smoke can cause significant hazards during a fire, including injuries and fatalities. By effectively containing smoke, these barriers help ensure that it does not spread to other areas, enabling safer evacuation paths and allowing fire suppression teams to better control the situation.

When smoke is contained, it mitigates the risk of smoke inhalation and exposure to toxic gases for occupants and first responders. Additionally, this containment allows for better management of the fire itself, as it can confine the fire to a limited area until it is extinguished. Overall, smoke barriers play a critical role in life safety and property protection during fire emergencies.
