What is the difference between a firewall and a fire separation?

So what is the difference between firewalls and fire barriers? Basically, firewalls are thick exterior walls with a higher fire-resistance rating, while fire barriers are interior walls with a lower fire-resistance rating.

Why is fire separation important?

Sometimes, despite your best efforts, fires can’t be prevented, but by taking the correct action beforehand, the spread of fire can be limited. Through effective fire separation or ‘passive protection’, property damage and business interruption exposure may be reduced, in addition to potentially saving people’s lives.

What is fire separation wall?

A firewall is a special type of fire separation assembly commonly constructed of non-combustible materials that subdivides a building or separates adjoining buildings. … The intent is that even in a severe fire, causing part of a building to collapse, a firewall will remain standing to prevent the spread of the fire.

How do you calculate fire area?

California law requires CAL FIRE to identify areas based on the severity of fire hazard that is expected to prevail there. These areas, or “zones,” are based on factors such as fuel, slope and fire weather. There are three zones, based on increasing fire hazard: medium, high and very high.

What is a fire area?

FIRE AREA. The aggregate floor area enclosed and bounded by fire walls, fire barriers, exterior walls or fire- resistance-rated horizontal assemblies of a building.

What is a separated occupancy?

Buildings that contain multiple occupancies must either be considered non-separated or separated. … Separated occupancies, as defined in IBC Section 508.4, require different occupancies to be separated using rated walls (fire barriers per IBC Section 707) and floors/ceilings (horizontal assemblies per IBC Section 711).
