Engine Ops Flashcards
Specific topics that shall be discussed after Roll Call “WARM”
Weather,
Areas of danger,
Response routes,
Modifications to normal response routes (Especially important for Covering & Detailed Off & Chauffeurs)
Single Unit Response: “Odor of Food BROILS”

2nd Due Eng will augment & assist 1st Eng in whatever tactics have been initiated unless _
Otherwise assigned by IC
Eng shall enter the block 1st followed by 1st Ladder. Exception:
Fire bldg located at end of a narrow dead end road
CR: Winter Ops- >3 stories Lad 1st
T/F Whenever possible- Only 2 HL’s operated from a pumper, Supply pumper in relay should not supply any HLs or LCS, & Pumper supplying LCS should not supply any HL or add’l LCS
True: if emergency requires exceeding these limits- the supply/operating pumper shall be augmented ASAP to ensure positive water & IC shall be notified
Rescue attempts by 1st Eng w/o simultaneously stretching & positioning HL should be attempted in extreme situations only. This should occur if “NO CAPT 4-5”
Number of persons trapped, Occupants endangered by fire, Cutoff by fire, Anticipated arrival of 1st Lad, PL ability to reach occupants, Threatening to jump, 4 or 5 FF eng Safety Teams shall be complied with
Off actions of 1st Eng to protect endangered occupants “AEDS”
Assure victims verbally,
Ensure incoming units notified,
Doors- close to limit spread of smoke,
Stretch HL between fire & occupant
3 Stages of Fire Suppression Effort
Locate fire: 1st stage of fire suppression (before fire attack- exact location of fire MUST be determined)
Confine/Control fire
Extinguish fire
Fire Growth dependent on “COSI”
Combustible content (fuel load),
O2 supply (vent openings),
Size of rooms,
Insulation of rooms
During Growth stage rollover may be present. Rollover serves as a warning that _
Most structure fires are _ regulated; Outside fires are _ regulated
Fire area may flashover
Air regulated; Fuel Regulated
Warning signs of Backdraft
Glass windows stained w/smoke condensation & pulsating from pressure of fire, Reversal of air pulling smoke back into a smoke filled opening, Dense black smoke indicates lack of O2 & large qty of free carbon & CO gas. Other colors include: Dirty brown, yellow brown, & gray yellow
After ordering 1st HL stretched Eng Off should enter fire bldg & begin gathering info. This info should include “FAST”
Fleeing occupants causing difficulties,
Absence/presence of wellhole,
Stairway type,
Transmissions from Lad company
If Lad company is forcing door to fire area- Eng Off should proceed to area immediately below fire & COLD
Ceiling check for structural weakness/holes, look
Out window to determine location & extent of fire on fire fl,
Layout of area,
Different view from below
T/F Noz team must begin every interior fire attack through the door to fire area crouched low, near the floor, regardless of conditions
True
Signals: 1 or 2 slaps on back or shoulder;
Tug/Pull on arm or noz either left or right;
Steady push on back or mask cylinder;
Pull back on shoulder, bunker coat, or mask assembly
Open/Close nozzle
Direction of stream
Advancement of HL
Halt or stop advance
What is the signal for immediate withdrawal of Noz team
Broken stream out window to assist in removal of heat & smoke- noz held _
4 Strong slaps on shoulder & pull in direction of retreat
4-5 feet back & fill opening
Decisions Officer can delegate to Noz team: DECALS
Direction of stream, Emergency opening of nozzle, Crackdown to regain control, Advancement rate, Line- calling for more, Sweeping floor w/stream
_ is useful where heat conditions require a very low approach to fire area
Duck Walking useful for “CHARD”
Crawling
Concrete floors (housing projects or office bldgs), Heat through bunker pants, Accumulated water, Rubbish or Debris that cannot be swept w/stream
Leg forward or Outstretched used for _
Emergency situation where stream can be operated directly overhead
Integrity of floor doubtful, Descending stairs & ramps, & Commercial occupancies
Room “lights up” overhead, & Fire rolls overhead or from behind
Specific Duties for 2nd Eng “LAWN”
Link for communications between 1st Eng & IC,
Account for members going above fire,
Water resource for 1st HL,
Number of members on fire floor- control
Dresser hydrants provide _% greater discharge than Smith hydrants
How are hydrant discs labeled
10-15%
Company number & Individual disc number marked in black on one side of each disc
Knock Down means
T/F Arrival of 2nd Eng is justification for 1st Due Control FF to leave his position
Have control of fire area w/o complete extinguishment
False: It eliminates reason to leave, now there are 3-4 FFs to assist w/stretch
Single kink in 1 3/4” HL produces loss of _ GPM or more. 3 kinks could lose _ GPM
20; 90 (ineffective & unsafe stream)
White line under the number on barrel of hydrant indicates
Hydrant on Dead End main & only supplied from one direction (smaller in diameter & provide less water)
What do Yellow hydrants signify
Found on Parkways & Expressways turned on using Curb Valve key (street side counter clockwise) turned 18 times to right.
CR AUC 325 Add High Pressure hydrants all yellow at airports
125 PSI LGA, 160 PSI JFK
Each Engine should maintain a minimum of _ lengths 1 3/4”, _ 2 1/2”, & _ 3 1/2”
Hose Manufacturer’s Name or Trademark Date of Manufacture location
Twenty 1 3/4”, Thirty 2 1/2”, Ten 3 1/2”
Both ends of hose NOT less than 4 feet from couplings
_ hydrants are on 30” diameter or greater mains
Red Air Cock (painted red & excellent source for FD use)
What is done w/broken custodian wrench
Delivered to Admin Division for replacement by Tech Services
Coupling Manufacturer’s Name or Trademark Date of Issuance to Unit location
Company & Registry numbers
Female coupling
Male coupling
2 1/2” shall be stretched for DALLAS
Defense position, Advanced fire on arrival, Large volume of water req'd, Large body of fire in large uncompartmented area, Area of fire cannot be determined, Standpipes
1st thread of both couplings is blunted w/_
Higbie cut to protect threads & make coupling easy
Can a rig drive over a hose line
Only if absolutely necessary: Charge HL if possible, avoid couplings, reduce speed, & 5” hose shall NOT be driven over unless properly bridged
Hose on rig is removed & cleaned _; Any hose that will reach _ years in current calendar year is to be taken out of service
Spring & Fall each year. 10 years
If serviceability of a length of hose is in doubt- what is done
Hose test procedure: Connect pumper to hydrant using inlet on _ side
Test it to 250 PSI
Side of rig opposite control panel spanner tight
The following defects during inspections would exclude hose from being tested “BMW CARGO”

Flame is issuing from windows opening onto fire escape & endangering people trying to come down fire escape. 1st HL may be operated from street
Short Stretch: Water shut down NOT req’d _
Adding hose to front of the stretch
Difficulty encountered due to volume of fire- fire escape used to conduct fire attack into apt. Before this is initiated _
Members must exit to safe area of refuge & apt door must be closed in order to preserve integrity of hallway & interior stairs
Well hole stretch: Noz FF for narrow well hole vs Wide well hole
Narrow: Noz FF drops folds at base of stairway, grasps noz & proceeds up stairway pulling hose up through well hole
