Deck 84 Flashcards
Situation #1 - Fire will not Darken Down or Cool DownAn engine company is making good progress advancing through a fire area and is suddenly stopped or slowed by fire that will not cool down or darken down.Possible causes for this situation are:? which are correct more then one.A- The stream is not adequately penetrating into the fire area.B- The stream may be inadequate for the size/intensity of the fire.C- A heavy body of fire may exist in another area which the stream is incapable of reaching.
All Correct5.3.19Possible solutions: The stream direction may need to be adjusted to enter the room more completely or an advance of a few more feet may be necessary to open another avenue or direction of attack. The gallons per minute (GPM) flow may be insufficient due to friction loss, low pump pressure or kinks in the line. A handie-talkie message to “increase pressure” or “get the kinks” may result in an increased flow and faster knock down of the fire. If fire exists in an area which is incapable of being reached by this hoseline such as the floor below or an adjoining area, this attack line must make a stand at this point and hold the fire until a back up line can be stretched. The second hoseline can be stretched to the other area involved or can be advanced together with the first attack hoseline to press the attack into the fire.
Situation #2 - Fire has Darkened Down But Will Not Cool Down Possible causes for this situation are: which following are correct more then one?A- The material and furnishings in the fire area have not been completely extinguished.B - Fire has extended into walls, floor and ceiling spaces and continues to burn there.C- Inadequate ventilation of the fire area.
All Correct5.3.19 GSPossible solutions: The areas where the fire was “knocked down” may need additional water application to completely extinguish all material, furnishings and structural components. Wall, floor and ceilings must be opened up to expose and extinguish any hidden fire. Initial or additional ventilation must be performed including the use of a fog or spray stream by the engine company.
The specific duties of the second arriving engine officer include: which are correct more then one?A-Water resource officer for the first hoseline.B- Provide a communications link between first due engine and IC.C- Control the number of members on the fire floor, limiting it to those necessary and directing others to appropriate staging areas below the fire floor.D- For reasons of safety, keep track of members going to the floor(s) above the fire. All members going to the floor(s) above the fire, before the fire is controlled, should communicate their identity to the second due engine officer before proceeding above.
