Chapter 2 Flashcards
Factors that influence fire behavior include:
Basic building classifications. Occupancy classifications. Fire or fuel load. Fire resistance.
Type I:
Fire resistive
Type II:
Non-combustible or protected noncombustible
Type III:
Exterior protected, masonry.
Type IV:
Heavy timber
Type V:
Wood frame
These features allow time for occupant evacuation and interior fire fighting
The addition of fire resistance. The fire resistive compartmentation provided by partitions and floors limits or slows Fire spread
Any substance, except plain water, that when applied to another material or substance will reduce the flammability of yours or slow their rate of combustion by chemical or physical action
Fire retardant
The use of___is the most common characteristic of unprotected noncombustible construction
Unprotected steel type II b
Type II B:
The speed at which unprotected members will fail depends on the following factors:
Ceiling height of the building. Size of the unprotected steel members. Intensity and duration of the exposing fire.
A fundamental fire concern with type three construction is the colon
Concealed spaces that are created between floor and ceiling joist in between studs and partition walls when they are covered with interior finish materials
The fundamental problem with type five construction is the presence of:
Concealed voids
This construction is considered the common currency of small residential and commercial buildings in North America today
Light frame construction
This construction technique was introduced to the United States in the 1830s
Light frame construction
Standard test method for behavior of materials in a vertical tube furnace at 750°C
ASTME136
The most commonly used test for determining combustibility is?
ASTME136
Indicates the ability of a structural assembly to maintain its load bearing capacity and structural integrity under fire conditions
Fire resistance
___Is the most common method used to determine fire resistance.
Laboratory testing
Also known as NFPA 251, standard method of test the fire endurance of building construction in materials
ASTME119
The earliest known fire test on building materials were conducted?
In Germany in 1884 to 86
In the United States the first known farts as were conducted in?
Denver Colorado in 1890 with subsequent tests in New York City in 1896
Reading assigned to a material or simply after standardized testing by an independent testing organization; identifies the amount of time and material or simply will resist a typical far, as measured on a standard time temperature curb
Fire resistance rating
Standard test methods for determining affects of large hydrocarbon pool fires on structural members and assemblies
ASTM standard 1529
The only standardized test method currently universally excepted by building codes
E119
Joint systems for floor to wall and wall to wall connections are tested in accordance with?
UL standard 2079, standard for fire test of joint systems
Type 1:
The addition of ________ increases structural integrity during a fire.
Fire resistance
