Most serious problem pertaining to fire spread in PD's? P. 271
Lack of enclosed stairway. Second major problem is no code requirement for interior finishes
One thing that is in favor for PD's is small rooms leading to containing fires but most peeps leave doors open. How should you handle? P. 271

Most authorities recommend what size of ventilation hole? P. 278
4 x 4. Spans two joist!!!
Quick cut ventilation method works well under what conditions? P. 280
Poor working conditions like limited manpower, straddling peak or working from a ladder or platform. This method spans one joist and is very effective on plywood.
Describe triangular opening? P. 279
1. Provides limited ventilation. 2. Spans several joist and hard to pull. 3. Limited by members reach and ability to maneuver basket. 4. Biggest advantage is it can be done inside a basket so you don't have to walk on roof.

When a fire has involved either a kitchen or bathroom what is the priority? P. 284
Get to same location on floor above and the top floor to see if fire is traveling.
When searching for fire or taking a line into heavy fire conditions what wall should you look for? P. 284 in MD
Wall behind toilet to open up cause the toilet has the biggest diameter pipe chase for spread
How to locate channel rails? P. 284
Most of time steel framing is used in class 3 ( ordinary) that is more than 25ft wide. The architects try to hide these thick walls like in closets.
When waiting for people to clear stairwell and to initate fire attack the door to fire floor must be kept closed and what windows should be broken for ventilation? P. 285
On floor landing between fire floor and floor above. These are often wired windows so bring big tools.
If searching floor above fire what apartments to search first? P. 286
Search apartments other than the one directly over fire first.
When to break out the 2 1/2 line in a MD? P. 286
When heavy fire is showing from 2 or more apartments on one floor. If only a single apartment that's even extending up to floor above.....intermediate lines are good enough.
Fastest method to select proper stairway for attack line? P. 287
Have member climb to second floor and locate the proper apartment line. Etc. 5b
If members choose the wrong stairwell to do fire attack and they find themselves isolated from fire area what type of stairwell is this? P. 287
Isolated staircase. This is the worst case scenario cause the stairs serve only one or two apartments. A similar type is the wing staircase since the staircase only supplies access to that certain wing.
Single stairs?p. 287
Serves all aparmtments
Transverse stairway? P. 288
When all staircases connect to a common hallway on each floor. You can cross over on any floor.
Line placemet in MD's? P. 288
First line to the fire floor via interior stairway. Second line in the same manner to backup first line ( can go to floor above but notify initial line first ). Additional lines should take alterante route to minimize stairwell congestion.
How to designate wings with throats? P. 289
Far left wing is A and then going right B and so on. Wings are separated by "throats" which is where staircases elevators, or compactors are found.
Where would you be able to make a defensive stand in MD's with wings if severe fire conditions prevent your advancement down the hall? P. 289
The " throat" area. In this case the aerial platform and trench cut make the best defense.
Which platform enables you to operate at top floor windows with master stream to penetrate ceilings and extinguish cockloft fires? P. 290
Telescoping boom platform
Two members should always immediately proceed where in MD's? P. 291
To the top of the stairwell landing to access roof cause alot of people go up stairwell to escape through roof
Is the benefits from sending someone up to roof for roof ventilation great? P. 291
Yes and it should take priority over other duties assigned even if there were peeps jumping out windows. This ventilation will decrease mushrooming there by leading others to not jumping!
3 points to know about fire escapes? P. 292
1. Dangerous. 2. Pick one that is not threatened by fire. 3. Most only go to top floor not the roof. Gooseneck fire escapes located in rear usually go up to roof put are very narrow thus hard to climb with equipment
3 ways to get to roof for roof ventilation if you can't take interior stairways for some reason? Etc. crowded! P. 291-292
1. Fire escapes- most dangerous. 2. Aerial device- preferred way. 3. Access roof from top of adjoining roof top. This is safer and quicker and should be first choice even over aerial
After crews vented over stairways they should go in and help with search duties..... How to get inside? P. 292
NOT FROM DESCENDING INTERIOR STAIRWAY!! Use rear fire escape first and if cant, go back down the way they came up and re- ascend via interior stairwell.
In a top floor apartment fire how can the roof team help the interior crew to speed up search and attack? P. 292
By venting the top floor windows from the roof with swinging pike pole, hook, or heavy tool. Cutting vent hole would help too!!
Two factors that have changed the way FF's must look at MD's? P. 293
1. The vacant building situation 2. Lightweight or truss construction
If fire is blasting down hallway and is within reach from an outside stream, what is the best way to reach? P. 297
Low rise buildings- set up aerial. In high rise building like 20-30 stories up use the antique Navy fog applicator in residential Another option is to breach adjoining room wall from stairway. A third option is drive back gases with a fairly narrow fog stream teamed with another straight stream line going through the fog stream. Setting up a PPV fan below the fire floor can help by pressurizing the stairway. This won't work iN 15-20 MPH winds. Last option is HR window curtain. This is all for the HR class 1 blowtorch effect.
Navy fog nozzle GPM's? P. 297
2-1/2 inch model (1-1/2 pipe) is 100 GPM's and 1-1/2 inch model (1 inch pipe) is 60 GPM's. If you drill out holes on jets = 150-175GPM's.
Describe a high rise window curtain that FDNY uses? P. 298

Duplex? P. 299
Apartments with living spaces on two floors connected by stairways. Triplex is exact same just three stories. Duplex often have all bedrooms on one floor.
Description of garden apartments? P. 301
New style usually low rise MD's from 1-3 stories but may go up to 6 stories of WOOD FRAME!!! Living room only on one floor. No interior stairs. Entrance to stairs is exposed to street or yard but still a big concern and must be protected.
Describe townhomes? P. 302
One family home attached to another home with up to 5 living levels connected by an interior stairwell. The wood frame construction and combustible siding poses a serious fire threat of extending.
Key difference between garden apartments, townhomes, and other dwellings? P. 302
The attached nature of the combustible exterior. Typical house tactics should be employed at all these but at garden apartments there might be a problem with accessing the building with preconnected lines. Too far!!
What is the biggest difference in fire operations from garden apartments and townhomes from other apartments? P. 303
The heavy prevalence of lightweight combustible construction. This will cause sudden catastrophic collapse. Mainly the roof and floor, not the walls.
The likelihood of collapse in townhomes and garden apartments shold prompt what? P. 304
A rapid blitz attack from a position outside of collapse zone.
How to deal with a cockloft fire in a garden apartment or townhome fire? P. 304-305
Remember they are lightweight construction so you can't get on roof to cut a big vent hole. The only place to stop the fire is behind a fire wall or party wall that goes from foundation to preferably through the roof at least 3ft above roof line. Roof opened up on safe side and ceiling pulled and hoselines placed.
What is a true firewall? P. 305
Built of brick and extends at least 3ft above roof
When planning a defensive fire in garden apartments or townhomes what factors to consider when setting up next to a fire wall? P. 304
1) first be aware of Mansard roofs which wrap around outside of buildings so fire can around them. 2) most so call fire walls in these buildings are not true fire walls but more like a common or party wall. 3) be aware that fire will burn out the trusses on the fire side of the party wall
Which is more deadly commercial or residential? P. 309
Commercial is almost 4 times more deadly.
Taxpayer? P. 309
A row of stores housed within a single building. Used to be class 3 construction but is now class 2 noncombustible. Now called strip malls.
Describe old style taxpayers? P. 310
Partition walls only run up to ceiling level with a cockloft that spans the entire building. Type 3 so it has Brick exterior walls with everything else wood. Can have up to 20 stores and often built with cellars.
Types of roofs of old style taxpayers? P. 310
1) flat roof. ( do 8x8 hole ) 2) inverted roof. ( do 8 x 8 hole) 3) metal deck on bar joist. 4) bowstring. FIMB. REMEBER CUTTING A TRENCH ON A TAXPAYER ISNT PRACTICAL AND SHOULDNT BE DONE.
Describe new taxpayers? P. 311
Class 2 so it has cement exterior walls with unprotected roof decking and steel bar joist that leads to early collapse within 5 mins. Increased size of first floor. NO CELLARS!! fire spread through cockloft just like the old taxpayers.
The key factor that allows us to operate in a taxpayer with a metal deck and steel bar joist? P. 312
Steel can be protected by applying a straight stream. A 2-1/2 attack line into fire store and a 1-1/2 line into the exposed stores on either side and sweep cockloft overhead. These steel roofs can fail in 5 mins.
How to deal with taxpayers that are of lightweight wood trusses? P. 312
Evacuate and then use a master stream from outside from ground level to blast ceiling.
One of the most beneficial places to spot the pumper on a taxpayer fire? P. 313
In line with and across the street from the fire store. This permits the use of a preconnected master stream or deck gun.
On taxpayers when do you break out with the 2-1/2 hoselines? P. 314
If fire isn't blowing out windows on arrival the hand lines can handle. In serious fires go with the 2-1/2.
Advantages of using a 2-1/2 line in a taxpayer? P. 314
1. Volume and reach- delivers about 250 - 325 GPM's and has a reach of more than 80 ft. The average store is about 75ft deep. 2. Manpower - under these circumstances all you need is 3 guys to pull line since , unlike residences, there are no bends or corners to maneuver......just go straight back!! 3. Stream power - the 1-1/4 inch solid tip nozzle at 50 a PSI does 325 GPM's which can knock hole in ceiling to get to cockloft
Where are taxpayers difficult to force entry? P. 314
At the rear. At least one ladder crew should always be assigned to the rear of all serious fires
How to ID front of store and have it match up with rear of store? P. 314-315
From left start with letter A and then with succeding letters go right. Write that letter on the rear door in back to coincide.
Where are taxpayers easiest to enter? P. 315
From the front. With rapidly extending fire simply break glass. But before doing so look for signs of backdraft which would be greatest at late night or early morning and in occupancies that are protected with steel gates.
If fire store is heavily secured in taxpayer how to proceed? P. 315
First force adjacent stores to cut off fire extension and then Force fire store.
What should you expect if you encounter steel gates besides of course backdraft conditions
1/8 inch Steel plating on roof and walls for burglars. Expect High temperatures and early collapse. If backdraft conditions change tactics to indirect method.
Indirect method? P. 316
Create a small triangular opening in roll gate , insert 2-1/2 fog nozzle and apply h2o. Direct a medium power stream up to ceiling to maximize steam
Describe cellars in taxpayers and why they are so dangerous? P. 316
Only one stairwell mostly found at rear of store and cellar ceiling is usually low (rapid heat buildup). Usually this stairwell is reached by trapdoor. Layout differs from first floor to cellars. Conveyor openings between first floor and cellar offers fire extension.
Only success of a taxpayer cellar fire? P. 316
Combine a fast high volume attack with immediate cutting of vent holes in first floor right above fire.
What line to use in a taxpayer cellar fire? P. 316
2-1/2 hose with 1-1/4 inch solid tip provides reach and volume. When entering a cellar always pull twice the length of the store plus one length and always charge before descending.
Line placement in a cellar taxpayer fire? P. 317
Attack line, backup line at base of stairs, and line on first floor to protect vent hole you just cut over fire. Vent hole should be 4 x 4 minimum and place man at top of cellar stairs for lookout.
What should you do if haven't knockdown cellar fire in a taxpayer in 10 mins? P. 317
Change tactics. Withdrawn attack line to safe area and place distributor and/or cellar pipe in operation over body of fire. Set up for defensive ops simultaneously. Once pipes have been going 1-2 mins , shut them down and try advancing again. Introduce high expansion foam from everywhere and flood first floor with master streams- cellar is doomed. Adjacent cellars will need vent and hoseline exposure prootection.
Terrazzo floors? P. 317
When masonry floors are placed over wood floor joists. Common in older drugstores, in new laudrymats and front sales areas.
2 other floors that are like terrazzo floors and should be treated the same? P. 318
Concrete and tile floors. All 3 floors weight about 150 lbs. per cu. ft. Bathrooms and front sales areas have tile floors.
Does discovery of a masonry floor automatically mean collapse? P. 319
No you have to find out the support system. If structure is fire resistive construction like 75 ft tall than support system is reinforced concrete and it is safe. Class 3 or class 5 then you have unreinforced concrete. Make an examination hole above fire in a safe remote area.
How to handle heavy cockloft fires in taxpayers? P. 320
Forget about involved store. Position 2-3 ( 1-1/2, 1-3/4, or 2 inch ) lines in each store several stores down. With 10ft hooks pull ceiling down the entire depth of store and at least 3 ft wide. Main body of fire attacked by preconnected deck gun or master stream. A heavy body of fire may require at least 800- 900 GPM's. Placing a platform at sidewalk level will give you 1000GPM's.
What is the major cause of total loss of taxpayers? P. 321
Cockloft fires. REMEBER they also pose the dangers of ceiling and parapet collapse.
How to check for a built up ceiling in a taxpayer from the interior? P. 321
Make a ceiling opening at the entrance to each area that has a suspended opening and poke upward with hook until you find roof boards. If hollow sound then you might have built up roof. If solid sound then you just hit the roof.
If advancing into a taxpayer and you see no fire overhead but you feel a great deal of heat what can be occurring? P. 322
Backdraft in the cockloft.
When it is physically impossible to open up the ceiling in a taxpayer cockloft fire... What to do? P. 322
Use cellar pipes and distributors. Meat markets and butcher shops are known to have Formica ceilings. REMEBER to pull all personnel from underneath ceiling before operating to avoid injury.
What aerial ladder is best to use when knocking down a cockloft fire through the front display windows? P. 322
The tower ladder stream is the most maneuverable and versatile on th fireground. Move side to side and store to store without shutting down.
How to open all metal overhanging soffit that is along the front of the row is stores that allows fire to extend to adjacent store? P. 323
Using pike poles is extremely difficult. A faster method is using a metal cutting circular saw from basket to cut fascia.
What is one of the most unrecognizable problems with a taxpayer cockloft fire? P. 323
Collapse of the parapet wall. A show window up front indicates that the wall is carried on a steel I- beam that is connected to another I - beam that runs through the cockloft. Cockloft fire will expand this beam pushing front I- beam out collapsing parapet above.
When there is a serious cockloft fire or fire blowing out the display windows from a taxpayer what should be included in the collapse zone immediately? P. 323
The entire sidewalk on all frontages. Entry should not be made or sidewalk stepped on until after cooling of steel beams.
Roof ops at a cockloft taxpayer fire demands what immediately if you hope to cut the required vent holes in time? P. 324
At least 6 members with 2 saws, 2 axes, 2 halligans, and 4 hooks. Truck ops at taxpayers are very demanding!
Highrise ops discussed in this book shold be applied to any building over how many stories? P. 325
Any building taller 6 stories!!
Does a building have to be 20- 30 stories tall to be considered a HR? P. 326
NO. Any fire-resistive building exceeding the length of your ladders or in which all FF ops must be done from interior because lack of windows must use HR strategies!
HR strategies?? P. 326-327
1. Determine fire floor. 2. Verify fire floor. 3. Begin controlled evacuation. 4. Gain control of building systems. 5. Confine and extinguish fire
When evacuating peeps from Class 1 HR's which people are considered to be in immediate danger at least initially? P. 327
Fire floor and floor above!!
How many FF's per floor to search HR buildings? P. 327
Minimum of 2 FF's per floor for small areas fires and more for larger areas or heavily charged floors.
When you shut down HVAC system in HR's what mode do you put them in? P. 327
Non-recirculating mode (all dampers open up to the outside air)
Why are peripheral air supply systems at perimeter of building dangerous? P. 327
They are a likely area for fire to extend to floor above.
Class 1 HR have evolved into, unofficially, into 3 categories? P. 328
Class 1 HEAVYWEIGHT- older HR are very fire safe Class 1 MEDIUM WEIGHT- modern glass towers have potential to be towering inferno. Class 1 LIGHTWEIGHT - total collapse expected at every advanced fire in a steel skeleton
Lightweight bar joist floor trusses protected by spray on fireproofing should be considered what? P. 330
A grave danger In the event of a serious fire.
HR designs classified into 2 categories? P. 329
Pre WORLD WAR II and post
Description of PRE WW II era HR's? P. 331-333
Stairways often enclosed in fire towers enclosed in 4 HR firewall, fewer places for hidden fire to travel, more compartmentation , no hung ceilings or blind spaces, fewer electrical fire sources, WINDOWS CAN BE OPENED FOR HORIZONTAL VENTILATION and the most important feature regarding fire spread.....NO CENTRAL AIR CONDITIONING TO SPREAD FIRE.
How do we know engineers were uncertain how much a load can carry in Pre WW II days? P. 331
Prewar buildings were often overbuilt. Even a steel I - beam was encased in cement. The general theme was re-Inforce everything just in case.
How do we know prewar Era also saw a strong concern for life safety back then? P. 332
With the numerous means of egress provided and they were usually remote from each other.
Disadvantages of newer style HR's ? P. 335
Lightweight material, poured concrete replaced by sprayed on fireproofing, curtain wall construction, hung ceilings, core construction, and wider open floor spaces.
What is a curtain wall? P. 335
Where the exterior walls are non bearing walls attached to the edges of the floors. This creates a gap at the floor level that fire can travel through.
A fire involving the first how many floors of a fully occupied office building is gonna require a risk vs benefit decision for the IC? P. 335
The first 4 floors. If old style HR be aggressive but if newer lightweight HR be more cautious.
What's the greatest threat to life in a MODERN HR's ? P. 335
Being unable to rapidly ventilate. Architects virtually tried to seal these buildings due to savings cost so they decided to make windows unable to open anymore. Good thing is that in these HR's collapse is very remote.
When modern HR's started to construct with windows not be made to open, what 2 problems did it cause? P. 335
Now you have to break windows for horizontal, and more importantly, the effect smoke and heat have traveling through the HVAC system.
Best method to use to deal with the spread of smoke in HR's? P. 336
Put smoke detectors in HVAC system that would shut the system down. If don't have this now you have to meet with building engineer
What's a good policy to have to help stop the spread of smoke in HR's? P. 336
Have building employees shut down all HVAC systems upon report of fire alarm.
Prior to selecting ventilation strategy two factors that are the most important in HR ventilation? P. 336
Wind and stack effect
When. An HVAC system be beneficial in HR fires? P. 336
In a relatively small fire where you can't justify breaking sealed windows. A moderate amount of smoke can be handled as long as it isn't hot enough to melt fusible links on dampers in the ductwork.
Stack effect? P. 337
More noticeable in buildings larger than 60ft and gets stronger as building gets bigger. Normal stack effect occurs when outside is cold and the warmer air inside rises out across the upper floors, spreading smoke, and out the building. Inverse or reverse stack effect occurs in air conditioned HR's when it is hot outside. The results in smoke moving down below the fire floor. Not a big deal but on hot days it can cause problems if is on the upper floors
What should you do to fix the phenomenon Stratificaion? P. 338
Vent this cold air out the top of building by creating controlled currents of air up the stair shafts and across smoked filled floors. This should also be done when smoke has been cooled by sprinkler discharge.
Stratification? P. 338
Occurs in sealed buildings when the smoke is not hot enough to rise to top of building.
When breaking glass in HR fires explain outside surrounding happenings? P. 340
Fire lines at least block away. Outside base of building cleared unless specific tasks is needed. Pumper drivers should stay in cab when not actually pumping. Lines supplying FDC or Siamese connections might need to be covered by plywood.
Explain the slogan " high, high or low, low is a NO,NO!"
This means if there is a HR fire on a hot day in the upper floors or cold day in the lower floors then venting windows is a no, no since the smoke will go in the building.
When is it an absolute necessity to use elevators? P. 341
Buildings higher than 20 stories. It's also a requirement if you want your reflex time under 45-50 mins.
Reflex time? P. 341
Time alarm is received until an effective fire stream is on the fire. GAINING ACCESS TO THE FIRE AREA IS THE SECOND BIGGEST PROBLEM IN HR FIRES!!!
At just about the practical limit of ascent by stairways two factors come into play to help us in ascending HR fires? P. 342
Sky lobby and blind shaft elevators.
Sky lobby? P. 342
Found in very large buildings. Combo of expressed blind shaft and segregated elevators with a sky lobby on an upper floor. At the sky lobby it is necessary to change from the express elevator to upper floors. Selecting an elevator that reaches only the sky lobby below the fire is safe to do.
Blind shaft elevator? P. 342
In very large buildings it is inconvenient to have elevators serve every floor instead they built elevators that serve certain floors. Elevator A serves floor 1-20 and elevator B serves floors 21-40 ( Elevator B rides through a blind shaft from floors 1-20) If fire on 12th floor it would be safe to take elevator B.
If taking elevators in a HR fire when do you get off? P. 342
2 floors below fire. If access stairs also serves fire floor also get off 2 floors below fire
If fire is within this amount of floors of the elevator lobby or sky lobby you should walk? P. 343
If fire is within 8 stories
When traveling by elevator what should you do at the first sign of trouble? P. 343
Force open the inner door to interrupt the interlock and stop the car right where is at. Also it's good practice to test emergency button. As soon as elevator starts traveling push it in. If stops pull out and continue on. If doesn't stop .....pop open the inner door. Stop every 5 floors.
While using elevator why do you stop every 5 floors? P. 343
Make sure elevator is still working. Verify nearest stairway. Check shaft to make sure is clear
When exiting elevator 2 floors below fire to find stairway for ascent when do you close and recall elevator back to lobby?? P. 343
Once you have made sure you are at proper location and secured access to stairs. Never stand in the elevator doorway. You can lay a length of hose across doorway to prevent door from closing.
How many ladder companies needed on fire floor to do search and check fire extension? P. 344
At least 2 companies on fire floor with another ladder company on floor above for search.
Preferred line for a HR fire? P. 344
2-1/2 line with 1-1/4 solid tip with only 50 PSI.
NFPA states that fire pumps are required to discharge their capacity at what PSI? P. 344
65 PSI at the highest hose outlet. It also limits pressure within a standpipe zone to 125PSI
In a HR fire when the volume of fire is even to much for the solid tip what can help out? P. 344
The lightweight master stream device. Light enough for one man
What is the problem with using a lightweight master stream in a HR fire? P. 345
These devices tend to have a kick back when angle is lowered to only 15-20 degrees which is needed in a 8-9ft ceiling height. Fix this problem by using 2 steel handled haligan hooks to span a door opening.
Describe core construction ? P. 346
Practice of grouping all non rentable space in a central core ( lobbies, stairs, air shafts, etc. ) This provides floor space in excess of 30,000 sq ft per floor.
NFPA 14 requires a standpipe system to supply a max GPM of what? P. 346
Pre 1993- 2500 GPM's. 1993 revision- 1250 GPM's
What should you do in a HR fire if you have a floor over 3000 sq ft that is fully involved? P. 346
Get above it and drown the entire floor above, wait to burn itself out and then handle manually.
In a HR fire In which you have broken windows on the upwind side and seat of fire is unattenable with hand lines what are some options? P. 347
Concrete core drill from underneath ( 8 inch diamond tip drill ) concrete cutting chain saw or the Lorenzo ladder. All these are last resorts. NO NAVY FOG APPLICATOR IN COMMERCIAL HR FIRES. ....area is too big to have any affect.
How to use a concrete core cutter? P. 347
There are two models. Both need a pump tank to cool tip. The smaller model only drills 4 inch holes so drill 3 holes in shamrock shape to pass a Bresnan distributor through.
Flow of Bresnan distributor? P. 347
About 485 GPM'S AT 100PSI with a 20-25 ft radius
A 6 inch reinforced concrete floor can be cut in about how many minutes? P. 347
5 mins
In a HR with core construction the fire might wrap around back onto itself and trap FF'S........solution?? P. 348
Fight your way out with 2 lines. One line for advancing and the other to remain at stairs to protect rear.
Explain the common problem with scissor stairs in HR's with core construction? P. 349
The scissors stairs exits the core on opposite sides. In this case when setting up on the floor below the fire connect to the standpipe opposite the fire side.
Access stairs? P. 349
Open unprotected stairway leading from floor to floor within a single occupancy.
What is the most crucial factor when preparing for a HR's fire? P. 349
Training all levels of FF's
Explain the systems unit in a HR fire! P. 350
This is basically like what our lobby control group does. A knowledgeable chief officer in charge here and assisted by a building engineer and a FF or officer to act as a coordinator
Explain Operations post in a HR? P. 350
Basically like our fire branch director. An ops chief is in charge of this and is sent to floor below fire to direct ops of fire floor and floor above. He should have blueprints of those floors. He must constantly push the fire attack teams so he might have to operate on fire floor sometimes. He should be assigned another chief and aide to handle communications.
Explain a forward staging area in a HR? P. 350
Another chief is usually the staging area officer in charge. Three floors below fire in close proximity of stairway with ample room for equipment and equipment. Another member assigned to chief for communication reasons. EMS sector with this area is a must. As a rule keep at least 2 attack teams and 2 support teams of threes members each equipped with forcible entry and overhaul stuff.
What will greatly improve the ability of the lines to advance in a HR? P. 351
Arrange for the orderly rotation for fresh personnel.
Explain stairwell support? P. 351
In charge of transporting equipment via stairwell if elevators dubbed unsafe. FF assigned every two floors. These FF can remove most of their PPE but keep it close just in case. If fire is on 24th floor then 12 FF's should be assigned here. It's ok to use non suppression personnel here like cops as long not in danger.
Describe search and evacuation post (SAE)? P. 352
Staffed by two members In a reasonably safe area above the fire (possible a sky lobby or floor not served by an elevator that serves the fire floor) Duties are to direct all fire forces operating OVER the fire floor and floor above. Of course in search of search operations. Take extra bottle cause they would work in smoky conditions.
Most fires at construction sites occur why? P. 353
Accidents or carelessness.
Construction sites might leave a fire watch after work...... How long do they stay after the site is shut down for the day? P. 353
Appr 30 mins after to make sure no hidden fire is there.
Stream of choice in a building under construction with a large floor on fire? P. 354
Elevating platform. A 2inch solid tip discharges more than 1100 GPM over a 100 ft deep floor.
First thing to do when using an elevating platform on a building under construction? P. 354
Clear all peeps from the streets below on the opposite side of the nozzle. Debris will be sent that way up 100 lb machinery.
How to use an elevating platform on a building under construction? P. 354
Usually in a normal building with more than one floor always start at lowest floor and progress upward....steam going up helps stop fire in these finished buildings. Buildings under construction you do opposite. Steam is nonexistent in these buildings.
Buildings higher than aerial ladders are usually supplied with a hoist....explain a hoist? P. 355
Similar to elevators. There are Two concerns with these hoist. One concern is they are usually shut down at night/weekends making for a long walk. The other concern is there are two types of hoist and it is IMPORTANT you know the difference to pick the right one to use.
How to tell difference of the two types of hoist used in buildings under construction? P. 355
One for people and one for material. The people one will always have controls inside and usually an operator inside....THIS ONE IS MEANT TO BE USED! The material one won't have controls in it and is not equipped with safety devices... DON'T USE THIS!!
Large quantities of flammable liquids and gases are kept in building under construction normally during what season? P. 356
Coder seasons. Fires in areas where LP cylinders are stored should be fought with large streams from a shielded area.
What should you be aware of buildings that are wrapped with tarpaulins? P. 356
They are wrapped to cure the buildings cement in cold weather. LPG is often used in here to fire the heater. A leak in these buildings will be treated as an indoor leak.
Ensure that fire protection systems are in place in buildings under construction are important but at a minimum should be what? P. 357
At minimum the standpipe riser and outlet should be within 2 floors of the highest level.
Are standpipe outlets usually left open in buildings under construction and why? P. 357
Cause plumbers like to use them to drain shit through. Close them or when you charge FDC the water will just pour out of these outlets. Outlets in the cellar are especially left open.
First arriving unit on a fire with a building under construction should make a habit and do what? P. 357
Test first floor outlet. If no water this means its dry and outlets are probably open so send someone up to close each floor outlet.
Two standpipe conditions found in buildings under construction? P. 357
Top of the riser is left open so the system is useless. Other condition involves a sectional valve that is installed to divide the system into more than one zone. These valves are closed to facilitate testing and sometimes left in the closed position. These valves are indicating valves , usually OS & Y
If you have a problem obtaining water from a system that you know is charged what should you do? P. 357
Check OS & Y valves. Usually found in mechanical room or in the staircase on the riser between the outlet that had water and the first one that doesn't. Only way to be sure is trace it.
If the spray on coating is missing from a steel I- beam or column what temperature will the steel fail at? P. 357
1500 DEGREES F. Steel cables under tension fail at 800F.
What should be done in an area in which fire is threatening steel racing cables? P. 358
Either cool cables immediately or prompt evacuation of area around.
Perhaps the most serious collapse threat in buildings under construction occur in what structures. ? P. 358
Structures that are "poured in place reinforced concrete" structures. Its in the first 48 hrs while drying that these buildings are most vulnerable. Ironically when these structures dry they are the most resistant to collapse too.
Things to know about " in poured concrete" buildings? P. 359
These floors are held up by plywood and 4x4's So the entire ceiling below the floor is plywood and if exposed to fire the floors will collapse like a domino. Fire streams can hit the plywood and temporary bracing and collapse too!!
If concrete in a "in pour concrete" building has already harden after 48 hrs why is it still dangerous? P. 359
Cause concrete takes appr 28 dys to reach its load potential but after the first 48 hrs the framework is stripped off to use somewhere else. The next 16- 20 days there will be 4 x 4's spaced every 8 ft...... Collapse potential.
What is spalling caused by? P. 359
The expansion of water trapped in concrete that occurs only upon direct flame impingement. Can cause explosive forces and concrete can spall at any age.
In partially occupied structures which floors tend to be rented out first? P. 360
The higher floors due to desirability of view. Lower floors remain unoccupied and used for temporary storage. Most construction codes allow these floors to remain unsprinklered even though the finished floors are sprinklered.
If builders object to installing temporary sprinklers in partial occupied structures what can you do? P 360
Forbid the use of any floors above the level where all fire protection systems are not working.
What is the most dangerous type of building in the US to fight a fire? P. 361
Vacant. FF deaths are more than 5 x in a vacant building than an occupied residential.
Do C- joist lightweight steel floor supports fail readily under fire? P. 361
How to mark vacant buildings indicating their hazard potential? P. 362
A box is marked at any entrance into building. 1. Empty box means normal stability and normal operations. 2. A box with one line diagonally means a building with some serious hazards and all operations should be done from exterior IF POSSIBLE. 3. A box makes with an X means severe hazards and all FF ops done from exterior.
Natural gas is formed as a result of what? P. 363
Natures action on organic matter over a million years. California, Oklahoma, louisiana, Texas, and West Virginia are the largest domestic producers of natural gas. Think COLT WV
What is natural gas composed of? P. 363
90% methane, 5% ethane, carbon dioxide, and nitrogen. Odorless and colorless. As little as 1/4 lb of mercaptan is added to 1 mil cu ft of natural gas for detection purposes. This makes it that as little as 1% of gas can be detected.
Vapor density of natural gas? P. 364
Vapor density is .60 which is lighter than air. Natural gas should rise rapidly.
Natural gas leaks can be divided into three categories. Name them in order of threat potential? P. 364
Inside leak- explosion potential. Outside leak- remember they can settle In Places to cause an explosion. Leaks resulting from fires.
High pressure transmission pipelines operate at what pressures? P. 364
350-850 PSI. These lines are used to ship gas from wells across the US
How should you deal with high pressure transmission pipelines? P. 364
Evacuate area, protect exposures, and check adjacent buildings for seeping. Do not attempt to close without gas reps on hand. Even if valves shut off and line is packed it will still leak for an extended period of time
City gate stations? P. 364
These stations receive the gas, reduce the pressure so that the utility company transmission system delivers at 60-150 PSI.
District regulator system? P. 364
Usually in underground vaults where the pressure is further reduced, depending on age and type, for the distribution center. Older system= low pressure= 1/4 PSI. Newer systems= high pressure = 2. 5-60 PSI

1/4 PSI
Order of delivery of natural gas? P. 365
High pressure transmission pipelines ( 350-850 PSI ) = CITY GATE STATIONS reduces to utility company's system pressure of = 60-150 PSI = district regulator system reduces to distribution system pressure of = 1/4 PSI
If a newer gas system is used what is needed at each house? P. 366
Since the newer systems operates at up to high 60 PSI pressures, a pressure regulator is needed at each house to reduce to 1/4 PSI cause appliances cannot use high pressures.
2 types of gas regulators? P. 366
Newer ones are spring loaded diaphragms And the older ones are called dead weight regulators ( mercury)
When a gas regulator fails the regulator should still keep the PSI at what number? P. 366
Regulator should still be able to keep it at 2-4 PSI. REMEBER it should normally be 1/4 PSI so this is still alot and could make high flames or even a sudden surge might blow out the flame totally with the result of gas buildup in house.
Peck vent or fisher vent? P. 367
Regulators located inside a building will have the vent line piped out through a wall to these type of vents to make sure that gas from a regulator failure doesn't build indoors.
District regulator failure? P. 367
When a district regulator fails and could bring mass disaster and casualties. When it fails in the open position the pressure downstream is increased resulting in over pressure to every gas service in the area.
What to do in a district regulator failure? P. 367
Alarm will be first to notice the sudden pattern. FD cannot do anything to directly solve other than notify utility company. Get a large number of resources in a staging area outside area. Use PA sytstem to notify residents to turn off all appliances May have to enter every building to shut off gas service. And search for victims.
Tactics for an indoor leak? P. 368
1. Notify utilities and their ETA. 2. Determine intensity an when first noticed. 3. Determine extent of evacuation. 4. Eliminate ignition sources. 5. Locate source and stop. 6. Search and ventilate. Note the first 2 steps can be done by alarm possibly
How does the FIT 8800 gas detector work? P. 369
Audible alarm rises as concentration increases so it allows you to follow leak.
Service entrance cock? P. 369
Where service enters the apartment building this master valve can stop the flow to all tenants.

Which gas systems don't have curb valves? P. 370
Low pressure services ( old ) and services with outside meters often dont have curb valves. High pressure and inside services do. Think LOW and OUTSIDE!!!
Can you use smoke ejectors to suck gas out of the area? P. 370
No even if they are labeled explosion proof. If additional venting is needed then use the fans outside to blow fresh in
Gas emergencies usually only one engine that needs to stretch a long should the line be? P. 371
Long enough to cover entire building. Water supply should be consistent with expected involvement.
Gas leaks outside usually take the path of least resistance which is where? P. 371
Often along the gas service pipe or other underground lines into buildings or manholes.
How to handle outdoor gas leaks? P 372
1. Notify utilities. 2. Approach upwind. 3. Stop all ignition sources. 4. Wait for utility company.
Last resort in outdoor gas leaks? P. 372
First, Do not touch any valves located in the streets . In smaller low pressure STEEL LINES go ahead and plug it. Under no circumstances though should you ever plug a plastic line or pipe as it might have static charge up to 3000 volts. A person grabbing the plastic line can ignite the gas.
How can a small gas fire be extinguished to get to a valve or save a life? P. 372
With dry chem, halon, or CO2 if necessary. For larger fires fog streams used to approach a valve.
Explain peak shaving time and why it happens in extremely cold weather? P. 373
Gas usually lighter than air. In cold weather demand goes up and when reserves are insufficient utility company just mixes in LPG . now the gas may not be so light and at times might approach 1.0 which is the same density of air. Now the gas may require mechanical ventilation to clear.
LPG? P. 374
A mixture of several hrdrocarbons but mostly propane. There's also butane and ethane
Propane? P. 374
Colorless, odorless and heavier than air so it sinks. Explosive range is 2.1% ( LEL ) and 9.5% ( UEL ). Turns into gas at -44 DEGREES F.
Vapor air explosion? P. 374
When a gas mixes with air. It maybe too lean at the floor to ignite and too rich at ceiling to ignite but in the middle just right. They are far more devastating than a leak that ignites immediately or even a BLEVE cause they have the opportunity to spread covering more space to ignite.
When propane gas is compressed enough what happens? P. 375
It shrinks to 1/270th its size. When it's is released by opening a valve it expands back to its gaseous state at a rate of 270 for each part of liquid that evaporates.
Pressure inside a propane cylinder is directly related to what? 375
The temperature of the liquid inside. @ 70 degrees the pressure is about 100 PSI. @ 100 degrees F the pressure is now about 190 PSI
BLEVE's can occur with which liquids? P. 376
ANY liquid in a closed container. Even water!! Remember BLEVE is a result of too much heat being applied to the cylinder in the wrong location In as little as 10 mins. Clear area at least 150ft in all directions.
The PRV on a propane cylinder is set to hold pressure at what amount? P. 376
250 PSI
To prevent a BLEVE large propane tanks require how much GPM'S? P. 376
At a propane emegency an engine shold locate a hydrant strong enough to supply how many lines? P. 376
3-4 lines( 1 1/2or 1 3/4 ). One line for the exposed building. One line outside to protect structure. One line to control cylinder fire.
At LPG incidents you should take cover when approaching cylinder until when ? P. 377
Until you have been cooling it for at least 2 mins. The spring loaded relief valve will shut off after being cooled.
What type of stream pattern on a LPG incident to use? P. 377
Use a straight stream on a narrow fog initially to place distance.between you and the cylinder. As you get closer the fog pattern must be widened.
Heating systems account for what percentage of fires? P. 377
21% of all fires.
Fuel oils come in how many different grades? P. 378
No. 1 ( lightest ) - No. 6 ( Heaviest ). Fuel oils have relatively safe flashpoints.

No. 3 oil? P. 378
A former imtermidiate grade which is no longer standard.
No. 4 oil? P. 378
Used in apartments and factories with a flashpoint of 130 degrees F. Requires no preheating.
No. 5 oil? P. 378
Has more impurities than No. 4 and also has the same flashpoint at 130 degrees F. needs to be preheated to flow easily.
No. 6 oil? P. 378
The heaviest of the oils with a flashpoint of 150 degrees F. Requires heating to get it to burn and flow easily.
Which oil grades are primarily industrial oils? P. 378
No. 5 and No. 6. Used in apartment complexes and large plants!!
For oil to burn what must be present? P. 378
Heat, fuel, and oxygen in sufficient quantities.
Components of an oil burner are divided into two systems? P. 378
The oil handling system and the oil controls.
Describe oil handling system? P. 378
Oil is drawn from tank through a pipe to the oil pump in the gun. Pump supplies oil to nozzle at high pressures so that it atomizes the oil. At end of the gun is a source ignition. Fire takes place in the firebox which has water coils inside too. The heat air flows around coils and the heated water is distributed through premises.
Most common burner is what type? P. 378
The high pressure gun type. The source ignition at end of the gun is usually a gas pilot light or two high voltage electrodes that are 5000 volts or more.
An oil burner safety circuit will shut down the pump and fan if it fails to ignite in how many seconds? P. 379
After 90 seconds.
The main or primary control feature of an oil burner consists of what? P. 379
A starting and running circuit that controls the fan, fuel pump, igniter, and safety circuit.
Name 3 limit control switches on an oil burner? P. 379
Pressuretrol, aquastat, and thermostat ( most commo of the three)
For a pressuretrol limit switch which setting is mostly used in residentials? P. 379
The max setting to limit dangerously high pressures. In large commercial occupancies the low setting maybe used too.
Aquastats are mostly found on what?p. 379
Steam and hot water systems.
What is the preferred means of interrupting the operation of the burner in an oil burner by the FD? P. 379
The remote control or emergency switch. It cuts off all power to the pump, fan, and igniter from a safe are like at the top of the stairs.
What is a stack switch on an oil burner? P. 379
Designed to sense the presence of heat in the smoke pipe. Keeps the oil and air mixture from building up if no fire available by shutting down the fan and pump. On newer burners this switch might be infrared.
2 potential oil burner problems? P. 379
1. Smoking burner ( easiest to handle ) 2. Delayed ignition or kickback 3. White ghost ( least common but most dangerous )
Describe a smoking burner? P. 379
For oil to burn cleanly without any clogging soot it must have the right air to oil mixture. When it doesn't alot of soot is created and smoke backs out of the firebox. Observe chimney upon arrival for thick black smoke ( remember burners should burn clean ). Turn off emergency switch and oil tank valve and advise to call a qualified repairman.
Describe delayed ignition or kickback? P. 380
When ignition doesn't occur immediately so oil vapors fill the chamber and smoke pipe. The primary control is still trying to light and if successful all the vapors will ignite all at one. The loud thud may knock the smoke pipe loose from the chimney or blow open the burner door. Burning oil may have pooled in the bottom of the firebox or out on the floor.
How to recognize and deal with a delayed ignition or kickback? P. 380
Frequently reported as an explosion in the cellar and upon arrival met with thick black smoke. If run out on floor and extended to nearby combustibles treat like a cellar fire. Shutdown power ( remote control )and fuel. Use extinguisher ( AFFF, dry chem, CO2 ) ONLY IF OIL IS BURNING OUTSIDE THE BURNER
What should you do in a delayed ignition or kickback when the fire is in the firebox? P. 380
Remember the firebox IS SUPPOSED to have fire in it. Allow it to burn itself out. Using water will cause firebox to crack.
The white ghost? P. 380
A cloud of vaporized oil and air heated above its flashpoint and out of its container looking for an ignition source.
When does the white ghost usually happen? P. 380
Commonly during severe cold spells cause it happens to oil burners that have been running for a long time, is shut down, and then shortly after is restarted. If there is an ignition delay the air/ oil mixture is vaporized by the hot firebox and a highly flammable fog like most that smells like fuel oil. Can blow out doors and floors.
How to handle white ghost? P. 380
Evacuate building immediately. Don't enter cloud Shut down remote using SCBA and wide fog for protection. Use fog to saturate and cool the heated mist. Vent. Secure. Shut off fuel.
What does black smoke mean? P. 381
1. Presence of a petroleum based product. 2 If a large amount is coming from the roof = roofing material. 3. If light smoke coming from the same place, the roof, it might be a defective oil burner. 4. Light to moderate coming from basement= oil burner malfunction = bring class B extinguisher.
Class A smoke? P. 381
Class A makes gray to light brown smoke when oxygen is present. But when less than sufficient oxygen is available then large amounts of dark grey or yellow gray smoke = backdraft.
Compounds containing oxides of nitrogen will give off what color of smoke? P. 381
A reddish brown hue. These are unlikely to be found in residentials or routine commercials.
The movement of smoke tells intensity of the fire...explain? P. 382
1. Heavy rolling violently twisting to the sky = extremely hot fire deep seated fire. 2. Wispy smoke light in color = incipient stage. 3. Heavy smoke throughout with no visible fire= cellar fire.
What is cold smoke? P. 382
Smoke settling in low spots. Found in sprinklered areas or where fire has been fully or partially extinguished.
Since smoke usually rises, the lowest floor with smoke usually has some fire. Where is it a good point to check? P. 382
Floor below this one.
Overheated fluorescent light ballasts usually give off visible smoke later in their emergencies...what type of smoke? P. 382

Give some reasons why you would smoke on several floors? P. 383
Elevator shafts, HVAC system through ductwork, incinerator shafts, compactor shafts. Always send someone down to the machinery room ASAP with a radio. Good idea to bring a halon or CO2 extinguisher just in case machinery on fire.
Why is it important to differentiate between a incinerator fire and a trash compactor fire?? P. 383
Incinerators have burners so they make shit burn anyways. Incinerator problems occur when shit gets stuck in the shafts blocking the escape of smoke. Smoke coming from a trash compactor needs immediate attention cause they don't hold fire so if you see this it means it can start extending.
How to handle incinerator trash fire? P. 383
Remove blockage. Examine each incinerator floor door. If smoke comes out you are below it. Keep going up until you find a door with no smoke. Now you are above it. Try to unclog with a hook or sash weights tied on a chain to push down and unclog.
