Which type of building material is affected by size and moisture content during fire
conditions? - ANSWER✅✅Wood
How does the size of a wooden structural member affect how it reacts to fire? -
ANSWER✅✅Heavy timbers remain strong even after exposure to direct flame.
, How does heat affect masonry? - ANSWER✅✅Stones and concrete may experience
spalling when they are heated.
Cast iron may crack or shatter when it is: - ANSWER✅✅rapidly cooled with water.
When heated, steel structural members tend to: - ANSWER✅✅elongate and push
walls outward.
Which factor is likely to affect the speed with which a steel structural member fails
under fire conditions? - ANSWER✅✅Size
How does reinforced concrete react to exposure to fire? - ANSWER✅✅It performs
well, but can lose strength through spalling.
Which type of building material is used to protect other materials because its
moisture
content gives it excellent heat resistance? - ANSWER✅✅Gypsum wallboard
What is a concern about lath and plaster during a fire? - ANSWER✅✅Conceals
hidden fires and adds fuel to the fire
Which statement describes how glass will react under fire conditions? -
ANSWER✅✅Heated glass may crack when water is applied.
Which type of building material can produce toxic gases and rapidly deteriorate
under
fire conditions? - ANSWER✅✅Oriented strand board (OSB)
Which building material can potentially be harmful to firefighters because it
contains a
glue called urea formaldehyde that gives off a hazardous gas when it is heated? -
ANSWER✅✅Particle board
When should firefighters begin considering the potential that a building will collapse?
- ANSWER✅✅During preincident surveys and size-up
Which type of collapse is common for a Type V construction building? -
ANSWER✅✅Walls collapsing inward
Why can abandoned buildings pose great danger of fire and collapse? -
ANSWER✅✅The interior may be gutted and altered.
In which stage of fire development does structural collapse become likely due to the
weakened state of structural members and buildup of water? - ANSWER✅✅The
interior may be gutted and altered.
, How do a building's contents affect fire growth and structural collapse? -
ANSWER✅✅Contents can retain water and increase the stress on structural
members.
Little or no water runoff from the interior of the structure can be an indicator that: -
ANSWER✅✅the structure is retaining water and at risk of collapse.
What is an indicator of structural collapse? - ANSWER✅✅Distorted structural
members
When establishing collapse zones,: - ANSWER✅✅apparatus must not be positioned
in the collapse zone.
Traditionally, how large is the collapse zone? - ANSWER✅✅1 1/2 times the height
of the structure
When should a collapse zone be established at a structure fire? - ANSWER✅✅Once
a defensive strategy is adopted
Once it is determined that collapse is imminent,: - ANSWER✅✅the collapse zone
should be cleared as soon as possible.
What should take place immediately after the collapse zone is cleared? -
ANSWER✅✅Personnel accountability report
Which statement accurately describes how building materials and configuration
affect
fire behavior in a structure? - ANSWER✅✅The longer the fire has burned, the more
likely it is that structural integrity has been
compromised.
Why are buildings under construction more susceptible to fire spread? -
ANSWER✅✅Sprinklers and FDCs are not yet operational
How can HVAC systems affect tactical ventilation? - ANSWER✅✅Move products of
combustion to unaffected areas
How can water from fire suppression affect a building's structural stability? -
ANSWER✅✅Water weight added from suppression can cause floors to collapse.
Overhaul operations may affect a structure's stability when: -
ANSWER✅✅firefighters accidentally cut through load bearing components.
Which should be continually evaluated for size-up? - ANSWER✅✅What resources
will be needed to resolve the situation
