What is the primary purpose of a draft curtain in fire safety?

• A. To enhance smoke detection
• B. To limit the mushrooming effect of heat and smoke
• C. To provide visibility in smoke
• D. To improve the efficiency of fire sprinklers

Answer: (B)

The primary purpose of a draft curtain in fire safety is to limit the mushrooming effect of heat and smoke. Draft curtains are installed in buildings to direct the movement of smoke and heat during a fire, which is crucial for effective smoke management. By containing smoke and heat within a designated area, draft curtains help prevent these elements from spreading to other parts of the building, thereby protecting occupants and facilitating a safer evacuation. They also assist firefighters in identifying and controlling the spread of fire and smoke, thus enhancing overall fire response efforts. This strategic use of draft curtains plays a vital role in ensuring that smoke rises to designated smoke venting areas instead of dissipating unpredictably throughout the space.
