NFPA 1033 LATEST 2026 TEST PAPER QUESTIONS AND
ANSWERS RATED A+
✔✔Flame Speed - ✔✔The local velocity of a freely propagating flame relative to the
fixed point.
✔✔Flash Point - ✔✔The lowest temperature of a liquid, as determined by specific
laboratory tests, at which the liquid gives off vapors at a sufficient rate to support a
momentary flame across its surface.
✔✔Flashover - ✔✔A transition phase in the development of a compartment fire in which
surfaces exposed to thermal radiation reach ignition temperature more or less
simultaneously and fire spreads rapidly throughout the space, resulting in full room
involvement or total involvement of the compartment or enclosed space.
✔✔Foam Concentrate - ✔✔A condensed form of a foam product.
✔✔Foam Solution - ✔✔A solution that results from foam concentrate and water mixing
in the correct proportions.
✔✔Freezing - ✔✔When leaves, needles, and small branches are heated by a passing
fire front, they become very soft and pliable. Prevailing winds or drafts created by the
fire bend them in the direction the fire advanced. Once cooled, they remain pointing in
this direction.
✔✔Friction Loss - ✔✔As water flows away from the source through a water system, a
progressive pressure drop due to changes in the direction of the pipe, length of pipe,
type of pipe, size of the pipe, types and sizes of fittings, and other components in the
line with the piping.
✔✔Fuel Analysis - ✔✔Identification of the first fuel ignited.
✔✔Fuel Gas - ✔✔Includes natural gas, liquefied petroleum gas in the vapor phase only,
liquefied petroleum gas--air mixtures within the flammable range, with the fuel gas or
the flammable component of a mixture being a commercially distributed product.
✔✔Fuel Items - ✔✔Any articles that are capable of burning.
✔✔Fuel Load - ✔✔The total quantity of combustible contents of a building, space, or
fire area, including interior finish and trim, expressed in heat units or the equivalent
weight in wood.
✔✔Fuel Package - ✔✔A collection or array of fuel items in close proximity with one
another such that flames can spread throughout the array.
,✔✔Fuel Rail - ✔✔An internal passage or external tube connecting a pressurized fuel
line to individual fuel injectors.
✔✔Fuel - ✔✔A material that will maintain combustion under specified environmental
conditions.
✔✔Fuel-controlled Fire - ✔✔A fire in which the heat release rate and growth rate are
controlled by the characteristics of the fuel, such as quantity and geometry, and in which
adequate air for combustion is available.
✔✔Fugitive Gas - ✔✔Fuel gases that escape from their piping, storage, or utilization
systems and serve as easily ignited fuels for fires and explosions.
✔✔Fulgurites - ✔✔Slender, usually tubular, bodies of glassy rock produced by electrical
current striking and the fusing dry sandy soil.
✔✔Fusible Plugs - ✔✔Thermally activated devices that open and vent the contents of a
container.
✔✔Gas Burner - ✔✔A device that allows fuel gases and air to properly mix and produce
a flame.
✔✔Gas-sensing Fire Detection - ✔✔A type of detector designed to sense a specific
gas, toxic gases, or a variety of gases and vapors produced when processing
hydrocarbons.
✔✔Ground Fuels - ✔✔All combustible materials below the surface litter, including duff,
tree or shrub roots, punky wood, peat, and sawdust, that normally support a glowing
combustion without flame.
✔✔Ground-Fault Circuit Interrupter (GFCI) - ✔✔A device intended for the protection of
personnel that functions to de-energize a circuit or portion thereof within an established
period of time when a current to ground (possibly a human body) exceeds the values
established for a Class A device.
✔✔Grounding - ✔✔A conducting connection, whether intentional or accidental, between
an electrical circuit or equipment and earth or to some conducting body that serves in
place of the earth.
✔✔Guide - ✔✔A document that is advisory or informative in nature and that contains
only nonmandatory provisions. A guide may contain mandatory statements, such as
when a guide can be used, but the document as a whole is not suitable for adoption into
law.
, ✔✔Halocarbons (Clean Agents) - ✔✔A chemical compound made up of carbon and
hydrogen, chlorine, fluorine, bromine, or iodine.
✔✔Halogenated Hydrocarbons (Halon) - ✔✔A chemical compound mixture of carbon
and one or more elements from the halogen series of elements (fluorine, chlorine,
bromine, or iodine).
✔✔Hard Times - ✔✔Specific points in time that are directly or indirectly linked to a
reliable clock or timing device of known accuracy.
✔✔Hatches - ✔✔Openings in a vessel's deck that are fitted with a watertight cover.
✔✔HAZWOPER (HAZardous Waste OPerations and Emergency Response) Standard -
✔✔The federal OSHA regulation that governs hazardous materials waste site and
response training. Specifics can be found in 29 CFR 1910.120
✔✔Headspace - ✔✔The zone inside a sealed evidence can between the top of fire
debris and the bottom of the lid.
✔✔Heat - ✔✔A form of energy characterized by vibration of molecules that is capable of
initiating and supporting chemical changes and changes of state.
✔✔Heat and Flame Vector Analysis - ✔✔A process to assist with fire spread analysis
and origin determination in which arrows representing the investigator's assessment of
the direction of heat/flame spread are placed on a detailed diagram of the fire scene.
The patterns can be traced back to the fire origin.
✔✔Heat Capacity - ✔✔The amount of heat necessary to raise the temperature of a unit
mass 1 degree, under specified conditions (J/kg-K, Btu/lb-(degrees)F).
✔✔Heat Detectors - ✔✔Initiating devices that operate after detecting a predetermined
fixed temperature or sensing a specified rate of temperature change.
✔✔Heat Flux - ✔✔The measurement of the rate of heat transfer to a surface, expressed
in kilowatts/m^2, kilojoules/m^2 sec, or Btu/ft^2 sec.
✔✔Heat Release Rate (HRR) - ✔✔The rate at which heat energy is generated by
burning.
✔✔Heat Shadowing - ✔✔A pattern that results from an object blocking the travel of
radiant heat from its source to a target material on which the pattern is produced.
