CERTIFICATION SCRIPT 2026 QUESTIONS
WITH SOLUTIONS GRADED A+
• Convection.
Answer: The transfer of heat by circulation or movement of the heated parts
of a liquid or gas
• There are several things that must be taken into consideration when __?__
for firefighting operations. Things to consider include: The distance of
Hosley, the volume of water needed, and the ease and speed of deployment..
Answer: Establishing a water supply
• Which class of fire extinguishers ratings contain numerical references?.
Answer: Only Class A & Class B
• What type of hose is used to actually fight fire and is the focus of this
module. Attack hose line usually comes in lengths of 50 feet - 100 feet with
internal diameters ranging from 0.75 inch - 2.5 inches?.
Answer: Attack hose
• What are the three ways to apply foam?.
Answer: 1.) bank in 2.) bounce off 3.) rain down "least effective"
• In general what will take precedence over stabilizing injuries before
moving?.
Answer: Remove from the IDLH area
• Degradation.
Answer: Destruction or decomposition of clothing materials due to exposure
to chemicals, usage, or extreme temperatures Indicators: - Stiffness or
excessive pliability - Tears, cuts, or abrasions - Damage to zippers or other
closures
• Vapor Density.
, Answer: Vapors with values less than 1.0 are considered lighter than air and
will rise. Vapors with values greater than 1.0 are considered heavier than air
and will sink.
• Has the foam been stored outside in the elements, has the foam expired, has
the stored foam been tested by the department or laboratory? These are all
questions to ask for determining if the poor foam production is due to the
__?__.
Answer: Foam itself
• In order for fuel to ignite, they must be in what state?.
Answer: Gaseous state
• Vapor Suppression.
Answer: Reduction or elimination of vapors Nature of material doesn't
change, but the hazard is immediately reduced
• Cryogenic Liquid Tanks.
Answer: - Capacity: 500-200,000 gal (most common is 1,500-11,000 gal) -
Working Pressure: Up to 250 psi - Hazard Class: 2.2 - Possible Contents:
Cryogenic Liquids - Examples: Liquid Oxygen, Liquid Nitrogen, Liquid
CO2, Liquid Argon, & Liquid Helium
• Radioactive Yellow-II.
Answer: Medium Levels of Radiation Maximum 50 mrems/hr at the
container OR 1 mrem/hr at 3ft from the container
• Closed Circuit SCBA.
Answer: "Rebreather" - Exhaled air is recycled - Usually lighter
Advantages: - The highest level of protection - No distance restriction -
Usually lighter than regular SCBA - May have a longer operational duration
Limitations: - Limited air supply -Limited work duration Risk of injury in
flammable atmospheres or system failure because of the presence of an
oxidizer
• Thermal Hazard.
Answer: Hazard related to temperature extremes Incidents involving
, flammable liquids, gases, solids & explosives
• Air Cooled System.
Answer: Consists of small air lines providing convective cooling of the
wearer by blowing cool air over the body Limited by the distance of the air
lines
• In facility fire operations, hose tools and equipment consist primarily of
what three things?.
Answer: * fire hose * nozzles * appliances
• In Scientific terms, fuel is known as the __?__.
Answer: Reducing agent
• What are the three basic types of affective fire streams?.
Answer: 1.) straight stream 2.) full fog 3.) power cone
• What is the process of tracking personnel within an IDLH so that trapped Or
injured firefighters can be identifies and rescued?.
Answer: Personnel Accountability system
• At what percent of oxygen concentration does significant impairment
begin?.
Answer: 17%
• Evaporation Rate.
Answer: The rate at which a material will vaporize (evaporate, change from
liquid to vapor)
• What causes a serious decrease in blood pressure, which can lead to failure
of the circulatory system. As well as thermal burns to lung tissue, causing a
long to fill with fluid, which eventually lead to asphyxiation?.
Answer: Inhalation of elevated temperatures
• True or false: fittings are used to connect hoses of different sizes and
threads..
Answer: True
• Flash Point.
, Answer: The minimum temp at which a liquid will give off sufficient vapors
that will ignite and flashover and. without additional heat, will not continue
to burn
• Roentgen Equivalent Man (REM), Millirem (mrem), and Microrem (μrem).
Answer: Rem is a large amount of radiation, so the mrem, which is one
thousandth of a rem is often the dosage encountered
• Type A Radioactive Packaging.
Answer: - Capacity: Small quantities of radioactive material with higher
concentrations of radioactivity than industrial packaging - Hazard Class: 7 -
Examples: Nuclear Medicines (radiopharmaceuticals), radioactive waste,
and radioactive sources used in industrial applications - 49 CFR 173.412
• Offensive Strategy.
Answer: Response options performed directly on the container or stressed
system to mitigate the incident. Containment: act of stopping the release and
preventing the spread of affected materials
• The ICS __?__ is built around five major components which are command,
operations, planning, logistics, and finance/administration.
Answer: Organizational Structure
• The older technology uses 3% foam concentrate for hydrocarbons, while
newer foams for hydrocarbons use a __?__ concentrate.
Answer: 1%
• Ton Containers.
Answer: - Max Capacity: Transport 1 ton - Internal Pressure: 100-500 psi -
Possible Contents: Liquified gases & some nonflammable gases - Moderate
BLEVE Potential - Hazard Class: 2.2 (anhydrous ammonia) & 2.3
(Poisonous Gas) - Examples: Chlorine, Sulfur Dioxide, Phosgene, &
Anhydrous Ammonia - Other Information: -- Convex design usually
contains refrigerant gases -- Concave usually contains Chlorine, Phosgene &
other gasses
• Chemical Reactivity/Change.
