What is defined as a continuous membrane designed to limit the spread of fire?

1. Fire wall

2. Firedoor

3. Fire barrier

4. Firestop

The correct answer is: Fire barrier

A continuous membrane designed to limit the spread of fire is best defined as a fire barrier. Fire barriers serve as structural components that prevent the passage of fire, smoke, and heat between different areas of a building. They are crucial for maintaining the integrity of a building’s safety systems, allowing for safe evacuation routes and protecting occupants in the event of a fire. Fire barriers are typically constructed of non-combustible or limited-combustible materials, adhering to specific fire-resistance ratings that determine how long they can withstand fire conditions. In distinguishing this from the other options, a fire wall, while also a fire protection measure, is a vertical separation that extends from the foundation to the roof and is designed to stand independently of adjacent structures, offering more robust protection but is not defined purely as a continuous membrane. A fire door is a component that provides fire protection by allowing access between compartments while still containing fire, but does not function as a continuous membrane itself. A firestop refers to materials or systems designed to seal openings or joints in fire-resistance-rated walls or floors to prevent the passage of fire and smoke, but again, it does not encompass the concept of a continuous membrane in the structural sense. Thus, the fire barrier is the most accurate
