Carbon Monoxide Poisoning - ANSWER This toxic condition does NOT cause a cherry- pink coloration to the skin of the fire victim and is NOT visible on all skin types Carburetor Backfire - ANSWER This occurrence is the most common open-flame ignition source in non-fuel injected vehicles Ceiling jet - ANSWER When the fire plume reaches the ceiling of a room and moves laterally along the ceiling Christmas Tree - ANSWER An item in the home that burns at a peak HRR of 3000- 5000kW, which is hotter than a pool of gasoline or a polyurethane chair Clean Burn - ANSWER This occurs when intense radiated heat or direct flame contacts a surface during the fire, burning away deposits Collapsed Furniture Springs - ANSWER This is a fire effect to furniture that does NOT provide the investigators with clues concerning the type of ignition source, but can show fire spread and intensity Color - ANSWER A fire characteristic that is NOT necessarily an accurate indicator of the flame temperature Color Codes - ANSWER This feature distinguishes the heat-sensitive bulbs of sprinkler heads from each other Combustion - ANSWER A chemical process of oxidation, which occurs at a rate fast enough to produce heat and usually light in the form of either a glow or a flame Compartmentation - ANSWER A building design feature that aims to limit the fire to its origin. Competent Ignition Source - ANSWER Located at the origin, these should be considered individually during the development of a cause hypothesis Complete PPE - ANSWER This should be donned when dealing with hazardous chemicals Conduction - ANSWER An example of heat transfer, when the heating of a steel beam to an unexposed part of a building results in a fire in that location Connection Points - ANSWER Overheating on a circuit is most likely to occur at this location on a circuit Joint Investigation - ANSWER Consensus agreement between interested parties should be developed prior to the commencement of WHAT?

Evidence Collection - ANSWER The process of photographing an item, then collecting, tagging and putting it in a log Evidence Collection and Documentation - ANSWER The importance of this fire investigative practice is no different in wildfire investigations, compared to structural fires.
