Deck 96 Flashcards
According to this bulletin, Flashover occurs when surfaces exposed to thermal radiation from fire gases in excess of _____ degrees F, reach ignition temperature more or less simultaneously. (Glossary)
In excess of 1100 deg. F
The on-going activity of assessing what is going on around you during the complex and dynamic environment of a fire incident. Your operations will be more effective and safer by continually observing your surroundings, communicating conditions to other members and monitoring H.T. transmissions. This is defined as ____________. (Glossary)
Situational Awareness
Ladder company operations have changed from VES to VEIS. Describe tactics when entering via a window and a door. (Glossary)
Thru a window: Close the door to isolate that room being searched. Perform search.Thru a doorway: the door needs to be controlled until the fire area is further isolated or a charged hoseline is advancing on the fire.
Modern content fires typically enter the decay stage earlier/later than Legacy content fires?
Earlier, due to the limited available oxygen, producing heavy smoke and varying heat conditions.
When a modern content fire enters its decay stage, and additional oxygen is introduced to the heated atmosphere thru ventilation openings, the fire will _________________. (2.1.6)
The fire will regain its energy, increase its heat release rate and enter into a rapid second growth stage, generating more heat and increased smoke production. This may be followed by a ventilation induced flashover and transition into the fully developed stage. The fire will either enter a second decay stage or be extinguished.
Any change to the fire conditions as the incident progresses or as a result of the ventilation tactics performed by members must be communicated to whom? (4.1)
The Ladder Co officer and the I.C.
True or FalseModern content fires generate a greater volume of heat and smoke that may overwhelm the ventilation point(s). The excess heat energy and smoke not being vented, rapidly pre-heat the interior causing the fire conditions to move toward any other opened ventilation point.
True
At which point may the roof firefighter begin roof ventilation? (5.1)
When H.T. transmissions are made indicating the ladder company is in the apartment and has control of the door, hoseline moving into the fire area, or after confirmation with the ladder company officer.
Once the engine company has a charged line outside the apartment door, the ladder company officer has 2 options based upon interior conditions. What are they? (pg 7 Fire Floor Ops)
- Direct the engine company to the fire area.2. If the fire could not be located or isolated, and based on the smoke and heat levels within the fire area, the interior team may need to re-group at the apartment door prior to opening the door for the hoseline advancement. Members should then advance behind the charged hoseline.
Agree or DisagreeAs per the Ventilation bulletin, the officer should utilize the T.I.C. to enhance the initial size up. If the officer encounters a high heat and smoke condition, he/she shall immediately isolate the area. Immediate ventilation will cool and relieve these conditions. (8.1.1)
Disagree.Ventilation will not sufficiently cool or relieve these conditions. A charged hoseline is needed to provide the required cooling of the area or extinguishment of the fire.
Give 2 benefits of coordinating vertical ventilation with door control of the fire area. (9.1)
- Vertical flow path can begin the remove heat, smoke and fire gases from the public hall and stairwell until the arrival of a charged hoseline.2. Relieves the upper portions of the building of heat, smoke and gases permitting a thorough examination of the hallways for potential victims.
Can the roof firefighter perform vertical ventilation without direct communications with the Ladder Company Officer? (10.2.1)
Yes. Providing transmissions have been made stating the interior team has door control on the fire floor or a charged hoseline is advancing into the fire apartment.
The member waiting to perform horizontal ventilation for extinguishment may vent…(11.4)a. upon hearing “Engine Officer to ECC- Start Water!”b. Engine Officer to Battalion- We are knocking down visible fire!”c. After communicating with the Ladder Co Officer inside the fire area to be vented and receiving permission.
C.Hearing transmissions A & B indicates to the OVM to PREPARE to conduct ventilation for extinguishment.
While all members of the FDNY must abide by the Federally mandated “2 in, 2 out” rule, rescue activity may be attempted under which 3 conditions. What are they? (12.3.1)
- Victim can be seen by the rescuer.2. Victim can be heard by the recuer.3. Member gets information from a credible source or a person at the scene indicating the location of the life hazard.
Anytime an individual firefighter enters an IDLH to address a life hazard, what must the Incident Commander do after the fire upon returning to quarters? (12.3.1 Note)
In all incidents of such individual action, the I.C. shall forward a report detailing the full particulars to the Chief of Operations. A thorough review of each of these incidents will be conducted.
