John Norman's Fire Officer's handbook of tactics 4th EditionFirefighter's Responsibility: - correct answer To protect Life and Property. Most Basic Principle of Firefighting: - correct answer Human life takes precedence over all other concerns. Concept 1 - correct answer When sufficient manpower isn't available to effect both rescue and extinguishment at the same time, rescue must be given priority. Concept 2 - correct answer When you don't have sufficient manpower to perform all of the needed tasks, first perform those that protect the greatest number of lives. Concept 3 - correct answer Remove those in greatest danger first. Generally, those in the immediate vicinity of the fire are in the greatest danger and should be removed first. The next highest priority is those directly above the fire. After these individuals, the removal may skip a floor or more and shift to the top floor, since this is where the heat and smoke will begin to accumulate more rapidly. Those people below the fire are usually the last priority. Concept 4 - correct answer When sufficient manpower are available to perform both tasks, they must carry out a coordinated attack. Concept 5 - correct answer When there is no threat to occupant, the lives of firefighters should not be unduly endangered. Sequence of actions - correct answer Locate, Confine, extinguish Six sides of possible fire spread - correct answer left, right, front, back, above, below The spread of fire within a building is: - correct answer usually faster then the rate at which fire spreads to an exposed building. However, when a large portion of a building or area is already involved and is threatening another structure, it is reasonable to protect the exposed building first. Last rule for firefighting is: - correct answer Let circumstances dictate procedures. When faced with a nonstandard situation you must be flexible enough to adapt and develop a proper solution. Size-Up can be described as: - correct answer an evaluation of problems and conditions that affect the outcome of the fire. Size-Up begins: - correct answer From the moment the alarm is received and it continues until the emergency is under control. It should include information gathered during the pre-fire planning stage. 20-Minute Rule; (potential collapse situations) - correct answer If a building (brick and wood joist or wood frame of standard construction; not lightweight construction; class III or class V) has been exposed to heavy fire for twenty minutes or more, it may be dangerous to enter. When does the 20 minutes of the twenty minute rule begin? - correct answer when the fire has reached flashover and begun to attack the structural elements. It can only be estimated. Unless you started the fire, you don't know when flashover began and started to attack the structure. What is the acronym for size up? - correct answer C O A L W A S W E A L T H S: Construction, occupancy, apparatus and personnel, water supply, auxiliary appliances, street conditions, weather, exposure, area and height, location and extent of fire, time, hazardous materials, special conditions. Life Hazard: - correct answer must be the deciding factor in determining tactics and procedures. Life hazard is the result of several other size-up conditions: Time of day, occupancy, location and extent of fire. The size up factors that combine to create Life Hazard: - correct answer Time of day, Occupancy, Location and extent of fire.
