What defines the term "fire barrier" in construction?

The term "fire barrier" in construction specifically refers to an assembly of materials designed to restrict the spread of fire and smoke between different areas of a building. Fire barriers are critical components in fire-resistance-rated constructions as they help to contain fires, prevent them from spreading from one compartment to another, and protect the occupants of a building by allowing safe egress during a fire emergency.

In terms of construction codes and standards, fire barriers must meet specific criteria, including the type of materials used, the fire-resistance rating, and how they are installed. This feature significantly enhances safety in buildings, establishing boundaries that effective suppression systems can support in case of fire emergencies.

The focus on preventing fire spread highlights the importance of such barriers in fire safety planning, distinguishing them from walls serving purely aesthetic functions or those that can be easily modified or removed.
