IAAI CFI & NFPA 921 flashcard set (without definitions) Overview of NFPA 921 chapters (minus the definitions chapter) in preparation for IAAI CFI test Questions and Answers

"Rule of Nines" - Medical concept, where major body areas are represented by increments of 9% *For example the head equals 9% 109F - In hyperthermia, what core body temperature is generally fatal within minutes unless treated? 4.0 to 10 w.c. - The typical water column range for gas service lines 4th Amendment - The amendment concerning search and seizure *Remember "knocking" 5th Amendment - The amendment concerning pleading, grand jury and double jeopardy *Remember "hand over mouth" 6th Amendment - The amendment concerning speedy trial, impartial, right to counsel, and face witness *Remember "point to wrist watch" Absolute - The temperature scale based on the lowest possible temperature of absolute zero Acute - A type of toxicity exposure that involves a one time exposure at a high level Advancing - The burned section of a wildfire that an investigator should enter first in order to begin examining the wildfire Aerial Layer - The layer in wildfire investigations, which begins at six feet above and up and includes branches, tree moss, and leaves Ambient Wind - The factor or force that can potentially overcome the fire's tendency to burn uphill, and in turn force the fire to burn downhill Ampacity - Conductor capacity Ampere - Unit of electrical current Arc - Luminous electrical discharge across a gap Arc Mapping - An electrical analysis that is fundamentally pattern recognition Arcing - An electrical event that is typically too brief and localized to be a competent ignition source Arson - From the standpoint of investigative preparation, documentation, and scene control etc., every fire should be approached as if it is potentially what type of fire? Arson Motives - Vandalism, excitement, revenge, crime concealment, profit, extremism, and pyromania are seven types of what? ASTM E1618 - What standard governs evidence collection for accelerant testing? Auto-ignition Temperature - The minimum temperature at which combustible substance ignites without spark or flame Axisymmetric Plume - A fire plume in the center of the room with no wall interface Backdraft - A low-order explosion that is the result of an oxygen-depleted fire that produces high concentrations of incomplete combustion products, with a sudden mixture of air into the accumulated fuels Battery - The only source of electricity in a vehicle when the engine is not running Blast Pressure Front - The expanding leading edge of explosion reaction, which is primarily responsible for explosion damage and injuries BLEVE - The most frequently encountered mechanical explosion BLEVE - An event that occurs when a vessel's contents are liquid and heating causes the liquid to exceed its boiling point and failure of the vessel occurs Rapid Boiling - This is the mechanism in a Mechanical Explosion, along with the expansion of pressurized gas Bow - The front of a boat Breaker Panel - In an electrical system, this device primarily functions as a main cutoff, electrical protection, and power distribution Buoyant Force - A force that is generated by temperature differences *Due to hot air rising because its less dense Buoyant Force - Fire plumes, ceiling jets and vent flows are examples of what type of force at work during a fire? Cable Staple - This structural component cannot be driven through insulation when properly installed 252 Calories & 1055 Joules - One BTU is equal to ________ calories *Which is equal to _________ Joules Carbon Dioxide - A type of suppression agent that is effective because it is non-corrosive, residue-less, non-conductive, and universally useful on most combustibles Carbon Monoxide - Binds with hemoglobin in the blood approximately 250 times greater than oxygen Cascading - Another name for a secondary or subsequent explosion Catalytic Convertor and Turbocharger - Name the other two hottest components in a vehicle, other than the exhaust system. Changed or Transferred - One law of energy says that energy can not be created or destroyed; but can only be what? Chemical Explosion - Flammable gases, vapors of ignitable liquids, combustible dusts, backdraft explosion, and aerosols are examples of fuels often involved in what type of explosion? Chronic - A type of toxicity exposure that involves a low-level of continuous exposure Closed - The type of electrical system that involves a current flowing in a loop or complete circuit. Combustibles - These materials produce essentially the same flame temperature as ignitable liquids. Combustion - A rapid oxidation process, as opposed to slow oxidation Commercial Propane - A type of gas that is liquefied under pressure for storage and is heavier than air (1.5 to 2.0 vapor density) Condensed-Phase Explosive - A solid explosive that is characterized by high pressures, crushing effects, and typically pronounced seats Condensed-Phase Explosion - Explosions involving a solid--as opposed to a diffuse fuel--in which the fuel and oxidizer is mechanically mixed or the material itself can be rapidly and molecularly converted Conductors - These provide a pathway for current to flow in an electrical system
