Essentials of Fire Fighting Edition 7 Chapter 4 Fire DynamicsTarget's the brain after being inhaled, ingested, or absorbed into the body - correct answer Hydrogen Cyanide us a product of combustion thaf does whaf to the body? Temperature - correct answer Measurement of the average kinetic energy in the particles of a sample of matter Heat flux to the PPE - correct answer Which measurement is often used to measure how long PPE will protect a firefighter in an interior fire environment Can cause heat stress and failure of the - correct answer Heat that is radiated to the insulating air layer between PPE and your body Amount of oxygen available for combustion - correct answer In most circumstances fires, the energy release in fire is directly proportional to what? Flammable (explosive) range - correct answer Combustion can occur within a range of concentration of fuel vapor and air; this range is referred to as what? Higher peak gear release rate - correct answer What is the likely result if additional air is allowed into an already ventilated compartment fire Extinguishing some of the fuel - correct answer Which action will transition a compartment fire in a modern structure from vent limited to fuel limited Chemical Flame Inhibition - correct answer Using an extinguisher other than water and foam to interrupt the combustion reaction is referred to as? Info gathered at scene - correct answer What provides the best indicators of structural integrity Open space with no complete fire barrier dividing it - correct answer A compartment is? Buildings under demolition - correct answer Where might firefighters be most likely to encounter inoperative standpipes and sprinkled systems Joules - correct answer What is energy measured in? Heat of Combustion - correct answer Potential energy available for release in the combustion process is known as? Pyrolysis - correct answer When a solid fuel is converted into a gaseous fuel Autoignition Temperature - correct answer The lowest temperature at which a combustible material ignites in air without a spark or flame. Chemical Energy - correct answer Most common source of heat in combustion reactions spontaneous combustion - correct answer May occur in an oxidation reaction when the heat generated exceeds the heat being lost? Heat of combustion - correct answer A fuels chemical content influences its heat release rate and its? Smoke Explosion - correct answer Form of fire gas ignition; the ignition of accumulated flammable products of combustion and air that are within their flammable range.
