Combustible Liquid - ANSWER A liquid with a flash point ABOVE 100F 12.5 - ANSWER If the current flowing out from an electrical panel is 12.5 amps, and it then flows through an electrical load of 1500 watts, what is the amperage of the remaining current flow of the return circuit? 1000 - ANSWER If a hair dryer draws 8.3amps (in a home with 120-volt service), what is the wattage? *Power (P) = current (I) x voltage (V) Watts = amps x volts 1987 - ANSWER The year of the first edition of NFPA 1033 1.5 times - ANSWER The recommended distance for securing the perimeter of a blast scene *That is, the distance from the furthest debris 1100°F - ANSWER What temperature in the upper gas layer causes the onset of Flashover? 1960°F - ANSWER The temperature at which copper melts 2 W/cm2 - ANSWER The measurement of the radiant heat flux (from gas layer to the floor) that indicates the onset of flashover 240 volts - ANSWER The voltage between the two hot wires at the service entrance cables in most single-family residences in the United States (single-phase service with three wires) 3 years - ANSWER The revision cycle for NFPA 921 (timespan) 350°F - ANSWER The flash point of power steering fluid 35-70 p.s.i. - ANSWER In high-pressure fuel-injected vehicles, this is the typical range of pressure that is used to pump fuel from a fuel tank 5 and 17 - ANSWER The lower explosive and upper explosive limit of natural gas (methane)? 680°F - ANSWER The ignition temperature of power steering fluid Fuel - ANSWER Any substance that can undergo combustion Act or Omission - ANSWER Two factors or situations leading to a fire that may show the nature of the incident responsibility. Additional Investigative Recommendations - ANSWER This concept should not be included in a summary report of findings. Admiralty Law - ANSWER A law that may govern the fire investigation of a boat After-market Equipment - ANSWER A type of device in a vehicle, which can cause an electrical overload to factory installed wiring Alive and Breathing - ANSWER Evidence of smoke or soot in the lungs, bronchi, and trachea is one of the most significant factors in confirming that, at the time of the fire, the victim was WHAT? All Team Members - ANSWER Those who have the responsibility for monitoring safety conditions at the fire or explosion scene 1220°F - ANSWER The melting temperature of aluminum Aluminum-to-pavement sparks - ANSWER Which one of these is NOT considered a competent ignition source? Metal-to-metal sparks, Aluminum-to-pavement sparks, Metal-to-pavement sparks, Motor bearing sparks Heat Release Rate - ANSWER A meaningful analysis of a fire requires an understanding of the fire growth, the total heat released, and WHAT? Arc-fault circuit interrupter - ANSWER What does he term AFCI stand for? And, the "A" specifically represents what? ASTM - ANSWER The organization that develops standard methods for testing materials Auto-ignition - ANSWER Initiation of combustion by heat but without a spark or flame Backdraft - ANSWER A deflagration resulting from the sudden introduction of air into a confined space containing oxygen-deficient products of incomplete combustion Backdraft - ANSWER An explosion caused by a combination of combustible materials heated to the ignition point and a sudden introduction of oxygen to support combustion Backfire Flame Arrestor - ANSWER A boat device that owners fail to keep clean, which is a frequent cause of engine compartment fires on boats Ballast - ANSWER A device on a fluorescent light fixture that transforms the voltage from normal household voltage to a higher voltage Battery - ANSWER The starter motor draws its energy from this source Beyond a Reasonable Doubt - ANSWER The burden of proof in a criminal trial Bimetallic Thermostats - ANSWER The component that controls temperature in many heat-producing appliances BLEVE - ANSWER This may occur when the vapor pressure of a liquid exceeds atmospheric pressure *And this is the most common mechanical explosion Boiling Point - ANSWER The temperature or point at which the vapor pressure of a liquid equals the external pressure applied Bonding - ANSWER The process of electrically connecting two or more conductive objects Bottom Passenger Side of the Windshield - ANSWER Most engine fires typically penetrate the interior compartment at this location of the vehicle Brass Prongs (male ends) - ANSWER An investigator can closely examine this component of a cord to determine if it was plugged into a receptacle Calcination - ANSWER The chemical and physical changes that occur in gypsum wallboard surfaces during a fire Carbon Monoxide - ANSWER A narcotic gas that one might be exposed to in the fire Carbon Monoxide - ANSWER The levels of this toxin dissipate over time after removal from the fire environment. 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
