I.
|
|
|
building construction helps a firefighter do what?
|
predict fire spread, determine structural integrity and recognize warning signs of a collapse
|
|
|
Masonry
|
Fire resistant
Poor heat conduction Prologned exposure, can collapse |
|
|
Concrete
|
Fire-resistant, poor heat conduction, strong, Spalling- mositure heated up (popping noise)
|
|
|
Steel
|
strongest material in common use, not fire resistant, good conductor of hear
|
|
|
Glass
|
non combustible but not fire resistive, ordinary glass will break when exposed
|
|
|
Gypsum board
|
not strong, good insulator, limited combustibilty (paper will burn gypsum itself won't, often a fire stop)
|
|
|
Wood
|
most common, highly combustible, weakends. Fire retardant chem. weaken wood
|
|
|
Plastics
|
Dense toxic smoke when burned, thermo plastic melt and drip, thermoset lose strength but dont melt
|
|
|
TYPE I Fire- Resistive
|
*concrete
All structure is non-combustible Fires are hot and hard to ventilate buildings w/ lots of people |
|
|
TYPE II- Noncombustible
|
*steel
All components not combustible, single story warehouses, severity of fire determined by contents |
|
|
TYPE III- Ordinary
|
*wood
Masonry extreior walls support walls, floors and roofs, no more than 4 stories, used in lots of building 2 types of fire load- construction materials, contents |
|
|
TYPE IV- Heavy timber
|
*all wood
could be eight stories, suitable for manufacturing and storing. Old school |
|
|
Type V- Wood Frame
|
most common, wood or other combustible materials
rapidly become full involves collapse frequently upt o four stories, wooden i beams and trusesses. no built in safety margin Balloon-frame- continous wood studs from basement to roof platform frame-wall studs not continous |
|
|
Building components
FFRTWDI (forget f r t. wives do incarcerate) |
foundation, floors and ceilings, roofs, trusses walls, doors &windows, Interior finishes and floor coverings
