NFPA 1983 3 Reasons for Venting - ANSWER Life safety, Fire Containment, and/or Property Conservation Type I building construction - ANSWER (fire resistive) buildings with structural members made of noncombustible material that have a specified fire resistance Type II construction - ANSWER (noncombustible) same structural members as Type I but without a specified fire resistance Type III construction - ANSWER (ordinary) noncombustible or limited-combustible exterior walls but with interior floors and walls made of combustible materials Type IV construction - ANSWER (heavy timber) same as ordinary Type III but with the interior walls, and floors made of large-diameter wood members Type V contstruction - ANSWER (wood frame) exterior walls, floors, interior walls, and roof structures made of wood. Class A foam - ANSWER used to fight fires involving ordinary combustible material such as wood, paper, and textiles. Also, effective on straw and hay. "reduces the surface tension of water" allowing the water to penetrate dense material. Class B foam - ANSWER used to fight class B Fires, to smother the fuel of the fire. Class A fire - ANSWER including ordinary combustible material such as wood, cloth, paper, rubber and plastics Class B fire - ANSWER flammable liquids and gasses Class C fire - ANSWER (C as circuit) energized electrical equipment Class D fire - ANSWER flammable metals such as potassium, lithium, sodium, magnesium etc. Foam concentrate - ANSWER mix with water and air to produce a solution that can serve as an effective extinguishing agent. What foam must be used on incidents involving polar solvents? - ANSWER AR Foam (Alcohol resistant) Alcohol-resistant foam - ANSWER Formulated so that alcohols and other polar solvents do not dissolve the foam. Class A Foam ratios - ANSWER 0.1 - 1% Class B Foam ratios - ANSWER 3 and 6 percent Protein foam - ANSWER made from animal by-products. They are effective on Class B hydrocarbon fires. Fluoroprotein foam (Fast spreading) - ANSWER made from the same base materials as protein foam but include additional fluorochemical surfactant additive, which allow this foam to produce a fast spreading film (FFFP) Film-forming fluoroprotein - ANSWER Composed of protein plus film-forming fluorinated surface-active agents, which make them capable of forming water solution films on the surface of most flammable hydrocarbons. (AFFF)Aqueous Film-forming foam - ANSWER A synthetic based foam that is particularly suitable for spill related fires involving gasoline and light hydrocarbon fuels. 2 types of foam proportioners - ANSWER foam eductor and foam injectors Foam eductor - ANSWER Draws foam concentrate from a container or storage tank into a moving stream of water. Foam injectors - ANSWER Add the foam concentrate to the water stream under pressure. Batch mixing - ANSWER pouring foam concentrate directing in to a apparatus tank Premixed foam - ANSWER is commonly used in 2 1/2 gallons portable fire extinguishers High-expansion foam - ANSWER used to completely fill a large space with foam Medium-expansion foam is produced with what type of nozzle? - ANSWER a special aerating nozzle Methods of foam application techniques - ANSWER sweep (roll-on), bank-down, and rain-down. Bulkhead - ANSWER Structure that decides the engine compartment from the passenger compartment Platform vs Unibody frames - ANSWER Platform uses beams to fabricate the load bearing frame of a vehicle. Unibody combines the vehicle body and frame into a single component (poured into a mold during manufacturing) Laminated vs Tempered glass - ANSWER Laminated is used in windshields of cars (3 layers) Tempered is used in side and rear windows that shatters into little pieces. NFPA 921 - ANSWER used to determine the origin and cause of a fire Mass arsons - ANSWER offender who sets 3 or more fires at same site/location during a limited time period Spree arsons - ANSWER offender who sets 3 or more fires at separate locations. (no cool off period) Demonstrative evidence - ANSWER anything that can be used to validate a theory or show how something could have occurred. Basic Signs of roof collapse - ANSWER sagging roof supports, indication that the roof assembly is separating from the walls (like appearance of fire or smoke near the roof edges), structural failure of any portion of the building, sudden increase in the intesity of the fire from the roof opening, and high heat indicators. Four standard methods of searching - ANSWER 1) Standard search 2) Oriented 3) O-VEIS (Oriented Vent Enter Isolate Search) 4) Team search What is the most effecient method to remove an unconscious or unresponsive victim from a dangerous location? - ANSWER a drag 4 Stages of fire development - ANSWER 1. Incipient Stage 2. Growth 3. Fully Developed 4. Decay 4 key attributes of smoke - ANSWER 1. Volume 2. Velocity 3. Density 4. Color The most frequently used hose size for interior fire attack? - ANSWER 1 3/4 inch Large handlines are defined as hoses that are at least what diameter? - ANSWER 2 1/2 inch diameter with a flow rate of more than 250 gpm Master streams can flow between - ANSWER 350-1500 gpm solid stream is what nozzle? - ANSWER smooth bore Fog nozzle can produce these two streams? - ANSWER straight and fog stream Propane (LPG) is in what state? - ANSWER a gas in it natural state. any temp higher than -44F What is added to propane to give its distinct smell? - ANSWER mercaptan Cool the upper part of the tank to cool the gas vapors. - ANSWER LPG fire Activities that prevent fire and limit their consequences? - ANSWER Stop drop and roll, EDITH (exit drills in the home), public safety education, fire safety inspections, and walk thrus smoke alarms should be mounted on the ceiling at least ___ inches from a wall. - ANSWER 4 inches If you can't do a ceiling mount, then mount the detector __ to __ inches below the ceiling as high as possible on the wall. - ANSWER 4 to 12 inches below the ceiling.

Which smoke detector is more common and less expensive? - ANSWER Ionization smoke detectors Double-action pull-stations - ANSWER require a person to perform two steps before the alarm will activate. Tamper alarm - ANSWER OSU EMT fire alarm with Shane Beam detector - ANSWER is a type of photoelectric smoke detector used to protect large open areas such as churches, auditoriums, etc. Spot detectors - ANSWER are individual units that can be spaced throughout an occupancy so that each detector covers a specific floor area Line detectors - ANSWER use wire or tubing strung along the ceiling of large open areas to detect an increase in heat.
