IFSTA Chapter 16 Question with
complete solution 2023
which type of building materials is affected by the size and moisture content during fire
conditions? - correct answer wood
how does the size of a wooden structural member affect how it reacts to fire? - correct
answer heavy timbers remain strong even after exposure to direct flame
how does heat affect masonry? - correct answer stones and concrete may experience
spalling when they are heated
cast iron may crack or shatter when it is - correct answer rapidly cooled in water
when heated, steel structural members tend to: - correct answer elongate and push
walls outward
which factor is likely to affect the speed with which a steel structural member fails under
fire conditions? - correct answer size
how does reinforced concrete react to exposure to fire? - correct 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? - correct answer gypsum wallboard
what is a concern about lath and plaster during a fire? - correct answer conceals
hidden fires and adds fuel to the fire
which statement describes how glass will react under fire conditions? - correct answer
heated glass may crack when water is applied
which type of building material can produce toxic gases and rapidly deteriorate under
fire conditions - correct answer oriented strand board
which building material can potentially be harmful to firefighters because it contains glue
called urea formaldehydge that gives off a hazardous gas when it is heated? - correct
answer particle board
when should firefighters begin considering the potential that a building will collapse? -
correct answer during preincident surveys and size up
which type of collapse is common for a type V construction building? - correct answer
walls collapsing inward
