Reason firefightersshould study
building construction
Firefighters know signsof collapse, speed of firespread, need for evacuation

3 Construction features assessed in
building size-upBuilt-in fire protection equipment, type of roof covering,types of doors and windows, roof design, age of building, building height, ventilation characteristics, egress path, security measures, type of construction, construction materials, modifications

Name 4 signs of a building collapse
Cracks or separation in walls, floors, ceilings, androof structures; evidence of existing instability; loosebricks, blocks or stones; deteriorated mortar between masonry; walls that appear to be leaning; structural members that appear to be distorted; fires beneath floors or in walls; unusual creaks orcracking noises; prolonged fire exposure
800
Damaged wall that would most concern firefighters:non-load bearing, veneer
orLoad-bearing, Fire
Load-Bearing Fire

2 fire risks forbuildings under
constructionAdditional fire load, and ignition sources; no fire protective features; disable fire protection systems; easy access to building; use of construction machinery

Difference betweenOlder vs. Newer
ConstructionOlder: exposed to weather;Not maintained; less fire

Difference betweenFire resistive vs.Non-combustible
constructionAll materials in fire resistive constructionare fire resistive; in non-combustible, flat roof is made of limited combustible materials
400
This is the formulafor measuring a
collapse zoneY=1 ½ x or Collapse zone= 1.5 x height of building
1200
This is what shouldhappen inside the collapsezone if a building collapse
is imminent
It should be evacuated
