TCFP Key Terms/Things to Know
Exam Questions and Answers
100% PASS
Backdraft—ANSWER-The explosive burning of heated gases that occurs when oxygen is
introduced into a compartment that has a high concentration of flammable gases and a
depleted supply of oxygen due to an existing fire.
Specific Heat—ANSWER-Amount of energy required to raise the temperature of a specified
unit mass of a material 1 degree in temperature
Water Hammer—ANSWER-Force created by the rapid deceleration of water causing a
violent increase in pressure that can be powerful enough to rupture piping or damage
fixtures. Generally results from closing a valve or nozzle too quickly.
Class A Fire Extinguisher—ANSWER-Used for wood, paper, cloth, and plastic fires, contains
pressurized water (Ordinary Combustibles)
Class B Fire Extinguisher—ANSWER-Used on hydrocarbon and alcohol-based liquids and
gases that will support combustion
Class C Fire Extinguisher—ANSWER-Electrical Equipment; includes all fires involving
energized electrical equipment
, Class D Fire Extinguisher—ANSWER-Combustible Metals (Dry Powder); ex: magnesium,
potassium, titanium, zirconium
Class K Fire Extinguisher—ANSWER-Cooking Oils (K = Kitchen); unsaturated cooking oils in
well-insulated cooking appliances (saponification)
Fire Triangle—ANSWER-Oxygen, Heat, Fuel
Fire Tetrahedron—ANSWER-Chemical Chain Reaction, Reducing Agent (Fuel), Oxidizing
Agent and Heat
Awareness Level—ANSWER-Lowest level of training established by NFPA for personnel at
Hazmat incidents
Operations Level—ANSWER-Level of training established by NFPA allowing first responders
to take defensive actions at hazardous materials incidents.
Incident Commander (IC)—ANSWER-Person in charge of the Incident Command System and
responsible for the management of all incident operations during an emergency.
Standard Operating Procedures (SOPs)—ANSWER-Standard methods/rules in which an
organization/department operates to carry out a routine function; usually found in a
policies/procedures handbook
Foam Elements—ANSWER-Foam Tetrahedron: Foam Concentrate, Agitation, Water, Air
Aqueous Film Forming Foam (AFFF)—ANSWER-Synthetic foam concentrate that, when
combined with water, can form a complete vapor barrier over fuel spills and fires and is a
highly effective extinguishing and blanketing agent on hydrocarbon fuels.
