What is the primary purpose of fire barriers?

The primary purpose of fire barriers is to prevent the spread of fire and smoke. Fire barriers are crucial components in fire prevention strategies within buildings and structures. They are designed to compartmentalize areas, effectively slowing down or stopping the movement of flames and smoke from one area to another, which is essential for protecting occupants, limiting property damage, and allowing for safer evacuation and firefighting operations.

By maintaining the integrity of fire barriers, the potential for fire to escalate and spread is significantly reduced, which can save lives and property during a fire incident. Unlike the other options, which focus on aesthetic, protective, or geographical aspects, the role of fire barriers is specifically rooted in fire safety and control, making them a vital part of any building's design and emergency safety planning.
