Building Construction Ch. 5 Practise Questions
Interior features of a building such as..... have a cumulative effect on the outcome of a fire event.
** Answ** wall coverings, compartmentation, and fire protection systems
The combustibility of interior finishes affects the behavior of fire in several ways: ** Answ**
1. contribute to extension by flame spread over walls and ceilings
2. affects fire growth rate (flashover)
3. adds to intensity by contributing fuel
4. produce toxic smoke gases contribute to life hazard
..... include the materials used for the exposed face of the walls and ceilings of a building, not
limited to structural. ** Answ** Interior finish/ interior lining (international)
Interior finishes can include: ** Answ** plaster, gypsum wallboard, wood paneling, ceiling
tiles, plastic, fiberboard, wall coverings including decorative furnishings, vegetation, draperies
Movable partitions are treated as interior finishes. Other materials that do not present a
continuous surface may be excluded from building code, including: ** Answ** countertops,
doors, window frames
Interior finishes may be classified as "trim" if they meet the following: ** Answ** 1. do not
exceed 10% of wall and ceiling area
2. distributed throughout space
3. do not constitute a large continuous surface
Flame spread over a specific material can be measured and predicted in degrees known as ...........
of the material when evaluating the following: ** Answ** -surface burning characteristics
1. composition, orientation and thickness
2. ventilation
,3. size and shape of a compartment
4. finish material on the ceiling or wall
The rate at which a fuel burns is determined by several factors. The most significant is ...... **
Answ** the combination of the fuel and the available oxygen
Materials with substantial access to the surrounding oxygen will burn ........ ** Answ** more
rapidly with a correspondingly higher heat release rate.
A thin product, ..... or less, will propagate flame more quickly when it is attached to ........ **
Answ** 1/4" or less
studs with an air space behind the material than when attached directly to more solid material
like gypsum
Building codes usually exclude surface treatments such as ..... and .... that are no thicker
than ....... ** Answ** paint and wallpaper
1/28th of an inch
If there are several layers of surface material, such as several layers of vinyl, the surface material
acts as ........ ** Answ** an insulator and will contribute to the spread of fire
When carpet is used as a wall covering, it is ............. ** Answ** tested as an interior finish.
Several types of fire retardant coatings that may be available include the following: ** Answ**
1. intumescent paints
2. mastics
3. gas forming paints
4. cementitious and mineral fiber coatings
...... expand upon exposure to heat to create a thick, puffy coating that insulates the wood surface
from heat and excludes oxygen from the wood. ** Answ** intumescent paints
, ...... forms a thick, noncombustible coating over the surface of the wood. ** Answ** mastic
coating
............. procedures include standardized methodologies that intended to control as many
variables as possible and yield meaningful results. ** Answ** Criterion Reference Testing
(CRT)
Reasons code officials do not accept fire retardant treatments for permanent applications: **
Answ** 1. Must be applied a specific rate and may require more than one coat.
2. May require reapplication at specific intervals
3. Fire retardant coatings only affect the coated surface
4. Fire retardant material does not increase fire resistance of structural unless tested as assembly.
5. May be used outside listings as alternatives to other required fire protection.
Interior finishes are tested to derive several measures of a materials flammability: ** Answ**
the flame spread factor and the smoke developed rating.
.......is standard test used to measure the surface burning characteristics of interior finish
materials. ** Answ** The Steiner Tunnel Test or tunnel test,
formally known as ASTM E-84
Building codes generally allow an increase in flame spread rating in buildings equipped with ......
** Answ** automatic sprinkler system
Flame spread ratings over ......... are not permitted in occupancies. ** Answ** 200
According to test protocol, the flame will travel along the (red) oak flooring ......... ft in ...........
minutes. ** Answ** 24 ft in 5 1/2 minutes
