Answers with Complete A+ Solutions
100% Correct!!!
Type 1 Construction - Correct Answer -The noncombustible construction type, made of steel
and concrete with fire resistance.
Type 2 Construction - Correct Answer -The noncombustible construction type, made of steel
and concrete; but with little to no fire resistance.
Type 3 Construction - Correct Answer -The Ordinary construction type, with masonry or
noncombustible exterior walls.
Type 4 Construction - Correct Answer -Heavy timber or mill construction type.
Type 5 Construction - Correct Answer -Wood framed construction type.
Upper Explosive Limit - Correct Answer -Which will create more damage in an explosion: the
Upper or Lower Explosive Limit?
,U.S. Coast Guard - Correct Answer -The entity, where an investigator can obtain recall
information regarding fire causes in boats and the manufacturer, model, and year.
Utilities - Correct Answer -An immediate concern to the fire investigator is the status of the
structure's utilities.
Ventilation Conditions - Correct Answer -This is a key consideration of the fire's characteristics,
when conducting a fire test or fire model, in order to validate the test.
Ventilation-Controlled Fire - Correct Answer -Fire in which the heat release rate or growth is
controlled by the amount of air available to the fire.
Ventilation Opening - Correct Answer -This firefighting tactic made directly above the fire will
help localize the fire.
Violent Explosions - Correct Answer -Fuel-air mixtures at or near the lower explosive limit (LEL)
do NOT always produce less than those fuel-air mixtures at or near the upper explosive limit
(UEL).
Weatherhead - Correct Answer -A specific device on a structure that is associated with
electricity and is part of the electrical system.
,Wet-Pipe System - Correct Answer -The most reliable type of sprinkler system.
Wildfires - Correct Answer -Weather history is an important factor when investigating these
types of fires.
Wood Trusses - Correct Answer -The failure of one of these types of construction features can
affect adjacent members of a similar type.
X-rays - Correct Answer -These medical procedures should be done of the entire deceased body,
including the clothing and associated debris found near the body.
Zone Model - Correct Answer -A type of fire dynamics analysis model that divides each room
into two or more spaces.
Computational Fluid Dynamics Model - Correct Answer -A type of fire dynamics analysis model
that divides the room into many cells.
Power (Watts) - Correct Answer -What is the product found by multiplying current (amps) times
voltage (volts)?
, Color coded sprinkler head bulbs - Correct Answer -Range from orange to black (Low to High).
Electrical Ignition - Correct Answer -The ignition source that requires that heat transfer from an
electrical source be maintained long enough to bring the adjacent fuel up to its ignition
temperature.
Up Position - Correct Answer -An outside screw and yoke valve is open when the stem is in the
up position.
Formula for Ohm's Law - Correct Answer -Volts = current times resistance (v=ir).
Formula for power - Correct Answer -Power = volts times current (p=vi).
Sprinkler head clearance - Correct Answer -Combustible materials must be kept 18 inches away
from this fire protection device.
Surface orientation of fuels - Correct Answer -The difference between wildfire V-patterns and
compartment fire V-patterns primarily lies in this.
Ignition by open flame - Correct Answer -One of the processes that vehicle motor oil is prone to.
