Ch 5- Interior Finishes and Passive Fire Protection Flashcards
Interior finish is also known as….
Interior lining
Name 3 fires that greatly influenced fire codes and proved interior finishes can contribute to loss of life?
LaSalle Hotel, Beverly Hills supper Club, Stations Night Club
Interior finishes may be classified as trim if they meet what conditions?
Do not exceed ten percent of the wall and ceiling area, Distributed through the space, Do not constitute a large continuous surface
Define flame spread?
Movement of a flame away from the ignition source
Define Surface-Burning Characteristic?
Speed at which flame will spread over the surface of a material
Define Compartment?
Any enclosed space without internal fire barriers
What is considered when evaluating for flame spread?
Composition, orientation, and thickness
Ventilation
Shape and size of a compartment
Finish material on the ceiling or wall
What is the most significant factor that determines a fuel burn rate?
Combination of the fuel and the available oxygen
Does a thin product of 1/4” or less propagate flame faster attached to non combustible material or attached to studs with air space behind it?
Attaching to studs with air space allows faster flame progression
Define Listed
a device or material that has been tested by any of several testing laboratories
What are the main testing laboratories
Underwriters, Factory mutual system
Define Intumescent coating
Coating or paintlike product that expands when exposed to the heat of a fire
What creates an insulating barrier that protects the material underneath by expanding when exposed to heat?
Intumescent coating
Define Mastics
heat resistant construction adhesive that bonds with most materials
What can be used as a flame retardant coating
Mastics
What are the four types of fire-retardant coatings?
Intumescent, Mastics, Gas-forming paints, cementitious and mineral fiber coatings
Measurement of one components tested performance against a set standard of criteria, not against similar components or assemblies
Criterion-Referenced Testing
Criterion-Referenced Testing is also known as?
Criterion-Referenced assessment
ASTM E-84
Standard test used to measure the surface burning characteristics of various materials
What is ASTM E-84 also known as?
Steiner Tunnel Test or Tunnel Test
Steiner Tunnel
Test apparatus used in the determination of flame spread ratings
Numerical rating assigned to a material based on the speed and extent to which flame travels over its surface
Flame spread rating
Measurement of the propagation of flame on the surface of materials or their assemblies as determined by standard tests
Flame spread rating
Smoke developed Rating
The measure of the relative visual obscurity created during the testing process by a known material
What would cause flame spread to be greater than tested value in ASTM E-84 tests in real world setting?
Room volume
Room Shape
Fuel loading in the room
What are the two test that test floor coverings?
NFPA 265 and 286
a measure of relative visual obscurity in an area because of the smoke generated by a burning material
smoke developed rating
What does the smoke developed rating not test?
heat, irritation, toxicity, volatility
What is a recently developed large scale test for evaluating contribution of wall and ceiling interior finish to room fire growth?
NFPA 286
Test procedures that incorporate the size and shape of rooms in a building
Corner tests
Test results should be used as what? and not guaranteed outcomes
Benchmarks
Who publishes the Fire Resistance Design manual?
Gypsum Association
Ul’s Fire resistance directory and Gypsum Association Fire Resistance Design Manual specify what details?
Materials that can be used
Allowable spacing of structural members
Type, spacing, and nail/screw patterns of the fasteners
Define Compartmentation
Series of barriers designed to keep flames, smoke and heat from spreading between spaces
What is rated assembly also known as?
Labeled assembly and fire-rated
Assemblies of building components such as doors, walls, roofs, and other structural features that may be required by code to have a minimum fire resistance rating from independent tester
Rated assembly
Shelter in place is also known as?
Protection in place
Defending in place
Sheltering and taking refuge
Having occupants remain in a structure or vehicle in order to provide protection from an approaching hazard
Shelter in place
Define fire wall
Fire rated wall with a specified degree of fire resistance
Define fire flow
The amount of water required to extinguish a fire in a timely manner
One of a set of sections in a building separated from each other by fire resistant partition
Fire area
In what type of construction is free standing walls found?
Type III or Type V
Freestanding walls mush be designed to resist a later load of at least how many psi?
5
The height of this wall is usually between 18 to 36 inches
Parapet Wall
What would allow for a parapet not to be used?
noncombustible roof that has a covering of low combustibility Class B
4 hour fire walls must be constructed with what materials?
concrete or masonry
Self supporting fire walls independent of the structures frame
Freestanding walls
Fire walls connected to a line of columns or steel structural supports with the same degree of fire resistance
Tied walls
Vertical extension of an exterior wall and sometimes and interior wall
Parapet wall
Fire barrier that extends from one floor to the bottom of the floor above or to the underside of a fire rated ceiling assembly
Fire partition
What provides a lower level of protection than a fire wall
Fire partition
What type of fire barrier is not required to extend continuously through a building
fire partition
Nonload bearing exterior wall attached to the outside of a building with a ridged steel frame
Curtain wall
usually the front exterior wall of a building intended to provide a certain appearance
Curtain wall
What is usually not continuous in a curtain wall assembly and therefore not an effective firestop
Support brackets
What is non load bearing and suspended by internal framing?
Curtain wall
The development of the steel framed high rise building led to the existence of the?
curtain wall
Curtain walls sever what functions
resist environment loads
control heat loss
limit noise transmission
limit solar radiation
Exposed interior surfaces of buildings, including fixed or movable walls and partitions, columns, and ceilings
Interior finish
