Should building security isolate a fire emergency by closing doors on the affected floor?

Closing doors on the affected floor during a fire emergency is a crucial action for building security as it helps to isolate the fire. By closing these doors, the spread of smoke and heat can be significantly reduced, which is vital for protecting occupants who may still be in the building and for maintaining the integrity of the escape routes. This measure also assists firefighting personnel by confining the fire to a smaller area, thereby allowing them to manage the situation more effectively.

In high-rise buildings, where fires can escalate quickly and where evacuations are more complicated, isolating the affected area is a key strategy in fire prevention and safety protocols. Closing doors can help minimize the amount of oxygen available to the fire, further controlling its growth and reducing potential damage. Overall, this action is widely recognized as an essential part of emergency response procedures in such scenarios.
