CONSTRUCTION

Type II Non-combustible

Masonry or concrete exterior walls with non-combustible roof assembly

Type V LightweightAll structural components are combustible

Combination ConstructionConcrete exterior walls with steel trusses and wooden roof

Parapet

Mansards & Facades

This building has tilt-up exterior walls, with a wood frame stucco covered mansard over the store front.

Mansard and Facades

Glass Store Front

Quick glass removal can provide good access, but remember the rush of O2 will draw the fire to the outside.

Fire Barriers

This is a stucco over wood strip center, connected with a masonry wall of a major tenant (anchor store). From the rear you can see a actual gap between the buildings. It will be covered with a metal strip on the front. This is a formidable wall.

The space between the strip mall and the major tenant is covered for aesthetic reasons. This is a sign of a good fire barrier.

This partition wall is constructed of sheet rock over metal studs. It will continue to the underside of the roof decking.

One side of this wall is sheet rock over metal studs. The other side is a cinderblock wall. This would be important information in the development of your IAP.

Mansards & FacadesYou can see how the decorative mansard on this strip mall provides multiple access for fire spread.

Mansards & Facades

This wooden mansard is bolted onto a cinder block building.

Mansard

Fire can potentially extend from a stripmall occupancy into an anchor store through the mansard.

These roof assemblies are vulnerable to early collapse. You need to get water on the fire and on the trusses early.

Rear Access

A block wall with a steel door can slow access to the occupancy. This door will need the skilled attention of a firefighter with a K-12 saw.

Rear Access

Rear access through lightweight construction may be easier through the wall.

Rear Access

This narrow space behind the building will force apparatus placement too close to the building.

CONSTRUCTION BENEFITS OF STRIP MALLS

Large Open Areas

From a safe position outside the occupancy you can apply water to the back wall and the roof assembly.

You can hit nearly everything from the front door in smaller occupancies.

Open Areas

Open areas and straight isles for easy advance

WALMART

Glass Store Front

Removal of glass provides a large opening for ventilation, hose streams and access. Remember fire will be drawn to you.

Masonry wall at anchor tenants

We know we have a substantial wall at this anchor tenant. We can use it to try to protect the “long” side.

Lightweight partition walls. Show how they can be forced easily.

if needed?Choose a location for the rescueWhere should later arriving units stage?Explain where you would utilize other

unitsIf the incident grew into a defensive

fire, discuss how you would assign units.
