Based on a structures occupancy classification what can a ff predict? -
answer Who is likely to be inside the building (OB)
What are building contents usually related to? - answer The occupancy of the
structure (OB)
What are the most commonly used building materials? - answer Wood,
engineered wood products, masonry, concrete, steel, aluminum, glass,
gypsum board and plastics (OB)
What are the key factors that affect the behavior of each of these materials
under fire conditions? - answer Combustibility, thermal conductivity,
decrease in strength at elevated temperatures, and thermal expansion when
heated (OB)
(True or false) Masonry is fire resistive and a poor conductor of heat. - answer
True (OB)
What would cause masonry structures to collapse under fire conditions? -
answer Roof or floor assembly collapses (OB)
What is concrete often used to do? - answer Insulate other building materials
from fire (OB)
Does concrete lose its strength when exposed to high temperatures? -
answer No (OB)
, How is spalling created? - answer Trapped moisture in the concrete becomes
steam from high heat (OB)
What happens to steel when heated? - answer It expands and loses strength
(OB)
When dealing with steel structural members what should be viewed as a
warning of imminent collapse? - answer Steel members bending, sagging or
stretching (OB)
Is glass combustible? - answer No (OB)
Tempered glass - answer Stronger than ordinary glass and more difficult to
break. Can be broken with a spring loaded center punch, it will shatter into
small pieces that don't have the sharp edges of ordinary glass (OB)
Laminated glass - answer Likely to crack and remain in place when exposed
to fire. (OB)
What type of glass was designed to prevent fire spread? - answer Wire glass
(OB)
What is the most important characteristic of wood and engineered wood
products? - answer Their high combustibility (OB)
What factors does the rate at which wood ignites, burns and decompose
depend on? - answer Ignition, Moisture, Density, Preheating and the size and
form (OB)
