MOD A FIREFIGHTER BASIC OPERATIONS UPDATED EXAM
SCRIPT QUESTIONS AND ANSWERS SURE A+
✔✔Two types of training records that are required to be maintained by the Division of
Personnel Standards and Education: - ✔✔-Learning objectives.
-Practical evaluations and written exams.
✔✔NFPA 1001 - ✔✔Standard for Fire Fighter Professional Qualifications
✔✔FIRE - ✔✔a form of combustion, self-sustaining process of rapid oxidation of a fuel
that produces heat and light
✔✔COMBUSTION - ✔✔self-sustaining chemical reaction yielding energy or products
that cause further reactions.
✔✔HEAT - ✔✔the form of energy that raises temperature, the energy transferred from
one body to another when the temperature of the bodies are different
✔✔IGNITION TEMPERATURE - ✔✔the minimum temperature to which a fuel, in air,
must be heated to start self-sustained combustion without a separate ignition source.
✔✔LOWER FLAMMABLE LIMIT ( LFL ) - ✔✔minimum concentration of fuel vapor and
air that will ignite. Limits below the lower flammable limit (LFL) are called too "lean" to
burn.
✔✔UPPER FLAMMABLE LIMIT ( UFL) - ✔✔concentration above which combustion
cannot take place. Limits above the upper flammable limit (UFL) are called too "rich" to
burn
✔✔FLAMMABLE (EXPLOSIVE) RANGE - ✔✔the range between the lower flammable
limit and upper flammable limit.
✔✔VAPOR DENSITY - ✔✔weight of a given volume of pure vapor or gas compared to
the weight of an equal volume of dry air at the same temperature and pressure.
✔✔SOLUBILITY - ✔✔degree to which a solid, liquid or gas dissolves in a solvent
(usually water).
✔✔Fire Triangle - ✔✔A. Heat
B. Fuel
C. Oxygen
✔✔Fire Tetrahedron - ✔✔A. Heat
B. Reducing Agent (Fuel)
, C. Oxygen
D. Chemical Chain Reaction
✔✔SMOKE - ✔✔mixture of solid particles, liquid vapors, and gasses
✔✔FIVE MOST COMMON FIRE GASES - ✔✔1. Carbon Monoxide ( CO )
2. Carbon Dioxide ( CO2 )
3. Hydrogen Cyanide
4. Sulfur Dioxide
5. Nitrogen
✔✔Three types of heat transfer - ✔✔-CONDUCTION
-CONVECTION
-RADIATION
✔✔CONDUCTION - ✔✔heat conducted from one body to another either by direct
contact or by an intervening heat medium
✔✔CONVECTION - ✔✔transfer of heat energy by the movement of air or liquid.
✔✔RADIATION - ✔✔transfer by heat waves
✔✔The Law of Heat Flow - ✔✔A. Heat flows from a hot substance to a cold substance.
B. A colder substance will absorb heat until temperatures are equal.
✔✔Three Physical States of Matter - ✔✔-SOLID
-LIQUID
-GAS
✔✔Phases of Fire - ✔✔-IGNITION
-GROWTH/FREE BURNING
-FULLY DEVELOP
-FLASHOVER
-DECAY
✔✔IGNITION - ✔✔occurs when the four elements of the fire tetrahedron come together
and combustion begins.
✔✔GROWTH/FREEBURNING - ✔✔fire plume begins to form above the burning fuel.
Begins to draw air from the surrounding space into the plume.
✔✔ROLLOVER/FLAMOVER - ✔✔the ignition of combustible gases, which have spread
thru the fire area. Differs from flashover in that only combustible gases are burning.
