STUDY QUESTIONS (GET ALL 100% RIGHT) STUDY
GUIDE GRADE A+
Fuel
Any substance that can undergo combustion
Act or Omission
Two factors or situations leading to a fire that may show the nature of the incident
responsibility.
Additional Investigative Recommendations
This concept should not be included in a summary report of findings.
Admiralty Law
A law that may govern the fire investigation of a boat
After-market Equipment
A type of device in a vehicle, which can cause an electrical overload to factory installed
wiring
Alive and Breathing
Evidence of smoke or soot in the lungs, bronchi, and trachea is one of the most
significant factors in confirming that, at the time of the fire, the victim was WHAT?
absolute temperature
Temperature measured in Kelvins or Rankines.
Accelerant
A fuel or oxidizer, often an ignitible liquid, intentionally used to initiate a fire or increase
the rate of growth or spread of fire.
accident
An unplanned event that interrupts an activity and sometimes causes injury or damage
or a chance occurrence arising from unknown causes; an unexpected happening due to
carelessness, ignorance and the like.
Active Fire Protection System
A system that uses moving mechanical or electrical parts to achieve a fire protection
goal.
ambient
Someone's or something's surroundings, especially as they pertain to the local
environment; for example, ambient air and ambient temperature.
Ampacity
The maximum current, in amperes, that a conductor can carry continuously under the
conditions of use without exceeding its temperature rating.
Ampere
The unit of electric current that is equivalent to a flow of one coulomb per second
Arc
High-temperature luminous electric discharge across a gap or through a medium such
as charred insulation.
,Arc Mapping
The systematic evaluation of the electrical circuit configuration, spatial relationship of
the circuit components, and identification of electrical arc sites to assist in the
identification of the area of origin and analysis of the fire's spread.
Arc
Combustible Liquid
A liquid with a flash point ABOVE 100F
12.5
If the current flowing out from an electrical panel is 12.5 amps, and it then flows through
an electrical load of 1500 watts, what is the amperage of the remaining current flow of
the return circuit?
1000
If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage?
*Power (P) = current (I) x voltage (V)
Watts = amps x volts

The year of the first edition of NFPA 1033
1.5 times
The recommended distance for securing the perimeter of a blast scene
*That is, the distance from the furthest debris
1100°F
What temperature in the upper gas layer causes the onset of Flashover?
1960°F
The temperature at which copper melts
2 W/cm2
The measurement of the radiant heat flux (from gas layer to the floor) that indicates the
onset of flashover
240 volts
The voltage between the two hot wires at the service entrance cables in most single-
family residences in the United States (single-phase service with three wires)
3 years
The revision cycle for NFPA 921 (timespan)
350°F
The flash point of power steering fluid
35-70 p.s.i.
In high-pressure fuel-injected vehicles, this is the typical range of pressure that is used
to pump fuel from a fuel tank
5 and 17
The lower explosive and upper explosive limit of natural gas (methane)?
680°F
The ignition temperature of power steering fluid
All Team Members
Those who have the responsibility for monitoring safety conditions at the fire or
explosion scene

Metal-to-metal sparks,
Aluminum-to-pavement sparks,
Metal-to-pavement sparks,
Motor bearing sparks
Heat Release Rate
A meaningful analysis of a fire requires an understanding of the fire growth, the total
heat released, and WHAT?
Arc-fault circuit interrupter
What does he term AFCI stand for? And, the "A" specifically represents what?
ASTM
The organization that develops standard methods for testing materials
Auto-ignition
Initiation of combustion by heat but without a spark or flame
Backdraft
A deflagration resulting from the sudden introduction of air into a confined space
containing oxygen-deficient products of incomplete combustion
Backdraft
An explosion caused by a combination of combustible materials heated to the ignition
point and a sudden introduction of oxygen to support combustion
Backfire Flame Arrestor
A boat device that owners fail to keep clean, which is a frequent cause of engine
compartment fires on boats
Ballast
A device on a fluorescent light fixture that transforms the voltage from normal household
voltage to a higher voltage
Battery
The starter motor draws its energy from this source
Beyond a Reasonable Doubt
The burden of proof in a criminal trial
Bimetallic Thermostats
The component that controls temperature in many heat-producing appliances
BLEVE
This may occur when the vapor pressure of a liquid exceeds atmospheric pressure
*And this is the most common mechanical explosion
Boiling Point
The temperature or point at which the vapor pressure of a liquid equals the external
pressure applied
Bonding
The process of electrically connecting two or more conductive objects
