What are the 5 major classification buildings are grouped in? - answer Type 1:
Fire Resistive
Type 2: Non Combustible or protected noncombustible
Type 3: Exterior protected (Masonry) or Ordinary
Type 4: Heavy Timber
Type 5: Wood Frame

NFPA 220 is over what? - answer Standard on types of building construction
In NFPA 220, each classification is designated by a _______________? - answer
Three digit number
Explain to me what each digit stands for in the NFPA 220 3-digit class -
answer 1st digit: Fire resistive rating (in hours) of exterior bearing walls
2nd digit: Fire resistive rating of structural frames or columns and girders
that support loads of more than 1 floor
3rd digit: Fire resistance of floor construction
Example of type 1 three digits
4-4-3. 3-3-2
Steel is what? But not _____________, and must be protected to attain
____________ - answer Non combustible, fire resistant, fire resistance
,In a type 1 structure the building is less likely to _______________ on
firefighters? - answer Collapse

Floor's fire resistance? - answer 2-3 hrs
Roof deck and construction supporting roof fire resistance? - answer 1-2 hrs
Interior partitions enclosing stairwells and corridors fire resistance? - answer
As specified by the local code, usually 1-2 hrs
Partitions separating occupancies or tenants' fire resistance? - answer As
specified by local code
Concrete is inherently non combustible material with good _____ properties. -
answer Thermal insulating
Reinforced concrete can fail under an________ or __________ - answer
Explosion, intense fire of long duration
What kind of wood is usually allowed in a type 1 buildings roof or interior
partitions? - answer Fire retardant- treated wood
What kind of plastics can be used in a type 1? - answer Light emitting, foam
plastics subject to restrictions
Type 2
In addition to steel and concrete block, _________ and __________ can be used
with structural load? - answer Glass and Aluminum
,Type 2
What omission can cause a type 2 construction building to be classified as
and inspected as a type 1? - answer Fire resistive ratings of roof construction
when the roof is more than 20ft above the floor
Type 2
Type 2 (a) protected requires that structured components have ________ fire
resistance? - answer 1 hour
Type 2
What is type 2 (b) - answer Unprotected non-combustible
Type 2
What is the most common characteristic of a unprotected non-combustible
construction? - answer The use of unprotected steel
Type 2
What factors will tell you the speed at which unprotected members will fail? -
answer -ceiling height of a building
-size of the unprotected members
-intensity and duration of the exposing fire
Type 3 exterior protected/ ordinary
Type 3 construction is frequently constructed with exterior walls of
____________ but from a technical standpoint, any noncombustible material
fire resistance can be used - answer Masonry
Type 3
Interior structural components that are permitted to be partially or wholly
combustible? - answer Walls, columns, beams, floors, and roofs
, Type 3
What are two ways a type 3 structure can be protected interior with a rating
of 2-1-1? - answer Plaster in older buildings and gypsum board in newer
Type 3
What nominal size does a type 3 construction commonly use as joist for floor
construction? - answer 2"x10"
Type 3
What does a nominal dimension mean? - answer Not exact
Type 3
What is a fundamental fire concern with a type 3 construction? - answer
Combustible concealed spaces between floors and ceiling joist and studs in
partition walls
Type 3
Concealed spaces in a type 3 construction must contain what? - answer
Appropriate fire stops
Type 4 HEAVY TIMBER
What is heavy timber also known as? - answer "Mill" construction
Type 4
What are the two important distinctions between type 3 and type 4
construction? - answer -in type 4 construction, the beams, columns, and
floors, and roofs are made of solid laminated wood with dimensions greater
than in type 3
- concealed spaces are not permitted between structural components in a
type 4
