Define Exposure?
|
The heat effect from and external fire that might cause ignition of or damage to and exposed or seperate part of the fire ground to which the fire could spread.

The Model building codes usually have five major construction classifications?
|
1) Fire Resistive 4) Heavy Timber
2) Noncombustible 5) Wood Frame 3) Masonry or Ordinary |
|
A warehouse containing cast iron radiators would have a light fire load but a very?
|
Structural Load due to the cast iron.

People who are unable to use stairs in a building for an emergency evacuation must be provided an area of refuge, this is?
|
A protected area for those people who cannot use the stairs and where they can remain temporarily until they receive assitance or instructions.. Examples are a stairway landing, smokeproof enclosure, balcony or protected vestibule.

The erection of buildings involes serveral branches of engineering and all of the building trades. The major engineering specialties are, Civil, Structural, Mechanical, Electrical, Fire Protection. The branch responsible for water supply is?
|
Civil Engineering

|
The fire resistance of structural components can be evaluated quantitatively and is known as the Fire Resistance Rating. The primary means used to determine a fire resisitance rating is?
|
To subject the component to be evaluated to the heat pf a fire in a test furnace.
|
|
The specific failure criteria in fire resistance testing depends on the specimen being tested such as a wall or floor assembly. The primary points of failure for the test are?
|
* Failure to support an applied load
* Temperature increase on the unexposed side of the assembly of 250 degrees above ambient. * Passage of heat or flame sufficient to ignite cotton waste. * Excess temperature on steel members. * Point Temperature. |
|
A noncombustible material is one that in the form in which it is used and under the conditions anticipated?
|
Will not ignite, burn, support combustion, or release flammable vapors.
|
|
Buildings are grouped into five major classifications, which are?
|
1) Type I Fire Resistive
2) Type II Noncombustible 3) Type III Exterior Protected (Masonry) 4) Type IV Heavy Timber 5 Type V Wood Frame |
|
Each classification of buildings is designated by a 3 digit number code. What does each digit stand for?
|
1) The first digit refers to the fire resistance rating in hours of the exterior bearing walls
2) The second digit refers to the fire resistance rating of structural frames or columns and girders that support loads of more than one floor. 3) The 3rd digit indicates the fire resistance rating of the floor construction. |
|
In Type I or fire resistive construction the structural members are of?
|
Noncombustible material that have a specified fire resistance. Eample : Steel is a noncombustible material but is not fire resistant.
|
|
In type I construction bearing walls, columns, and beams are required to have a Fire Resistance of how many hours?
Floor construction how many hours? Roof construction how many hours? |
1) 3 or 4 hours
2) 2 or 3 hours 3) 1 or 2 hours |
