1.Types of building construction -
NFPA 1001: 3-3.11
2.All firefighters should have a basic knowledge of the principles of
building construction.
,Knowledge of the various types of building construction and how
fires react in each type give the firefighter and the fire officer an
edge in planning for a safe and effective fire attack.
3. TYPE I (FIRE-RESISTIVE) CONSTRUCTION -
structural members (walls, columns, beams, floors, roofs) made of
noncombustible or limited combustible materials, fire-resistive
compartmentalization, primary fire hazards are the contents of the
structure, ability to confine fire may be compromised by openings
(in walls, ceilings or floors), overhaul is difficult, sprinklers and fire
resistive coating on all structural members.
4.TYPE II (NONCOMBUSTIBLE OR LIMITED COMBUSTIBLE)
CONSTRUCTION -
similar to fire-resistive construction except that the degree of fire
resistance is lower, has a fire resistance rating on all parts of the
structure (exterior, load bearing walls and building materials),
materials with no fire-resistance (untreated wood) may be used in
limited quantities, one of the primary protection concerns is the
contents of the building, heat buildup from a fire can cause
structural supports to fail, type of roof may be a problem (often
have flat, built-up roofs containing combustible felt, insulation and
roofing tar) and fire extension to the roof can eventually cause the
entire roof to become involved and fail.
5.TYPE III (ORDINARY) CONSTRUCTION -
(very common construction type from 1900-1950's) Exterior walls
and structural members constructed of noncombustible or limited
combustible materials, interior structural members (walls, columns,
beams, floors and roofs) are completely or partially constructed of
wood (in smaller dimension that that required for Type IV heavy
timber construction), primary concern is the problem of smoke and
fire spreading through concealed spaces (between walls, floors and
ceiling), heat from the fire may be conducted through finish
materials (drywall, gypsum board or plaster), building collapse is a
major concern with this type of construction
6.TYPE IV (HEAVY TIMBER) CONSTRUCTION -
features exterior/interior walls and their associated members made
of noncombustible or limited combustible materials, other interior
structures (beams, columns, arches, floors and roofs) are made of
solid or laminated wood with no concealed spaces, dimensions must
, be large enough to be considered heavy timber (this type of
construction was used extensively in old factories, mills and
warehouses, occasionally today in churches), primary fire hazard is
the massive amount of combustible contents in the building, heavy
timbers remain stable for a long period of time under fire
conditions, but give off tremendous amounts of heat posing a
serious exposure problem for firefighters.
7.TYPE V (WOOD FRAME) CONSTRUCTION -
typical single family residence, wood-frame construction
(exterior/interior walls, floors, roofs and supports completely or
partially constructed of wood), unlimited potential for fire extension
within the building of origin and nearby structures, firefighters must
be alert for fire coming from doors or windows.
8. WOOD -
used in various structural support systems, reaction of wood to fire
depends upon the size of the wood and the moisture content of the
wood (the smaller the size the faster it loses structural integrity, the
higher the moisture content the slower the rate of burn), water
used during extinguishing operations does NOT have a substantial
negative effect of the structural support strength of wood
construction materials, applying water to burning wood minimizes
damage by stopping the charring process.
9. MASONRY -
includes bricks, stones and concrete masonry products, commonly
used for fire wall assemblies (fire wall), block walls may be load
bearing, most brick and stone walls are veneer (decorative), bricks
rarely show signs of serious deterioration, stones may lose portions
of their surface (spelling), blocks may crack but usually retain most
of their basic strength and stability, the mortar between bricks
should be checked for weakness, rapid cooling from extinguishing
operations (water) may cause masonry to crack (common problem in
chimney fires).
10.CAST IRON -
rarely used in modern construction, typically found in older
buildings and commonly used as an exterior surface (veneer walls or
ceilings), stands up well to fire but may crack or shatter when
rapidly cooled with water, primary concern is that the nuts or bolts
