Q

2 Main categories of foam

A

Low Ex

High Ex

2
Q

Low ex foams are extremely useful on fire and spills involving

A

Flammable and Combustible liquids

3
Q

High Ex foams are intended to fight fire of

A

Class A combustible materials in areas that are inaccessible to firefighters, such as cellars and ship holds.

4
Q

High Ex foam is not suitable for use on

A

Outdoor flammable liquid fires

5
Q

An important point to be considered is that the fire must be

A

Completely extinguished or it will burn back across the surface as soon as the particular extinguishing agent begins to breakdown

6
Q

Different types of foam concentrates are not

A

Compatible and should never be mixed for storage. ex: in the tanks of foam carriers, Tenders

7
Q

At an incident it is permissible to apply

A

2 different types of Low Ex Foam simultaneously if necessary due to a lack of sufficient quantities of the most correct type to complete extinguishment. Ex: Fluoroprotein and Alcohol (Polydol).

8
Q

Can u mix High Ex and Low EX

A

NO

9
Q

Protein Foam is

A

Not used by the FDNY, however it might still be encountered at some bulk plants

10
Q

When using a AFFF extinguisher knockdown will be observed but the film produced might be

A

Unstable because it in not aerated. Breakdown around hot metal especially pipes in a boiler room should be anticipated. As a precaution a foam line should be made ready

11
Q

AFFF is not an

A

Aerated Foam

12
Q

Port Authority crash trucks use

A

AAAF Foam

13
Q

It is important to recognize the fast draining nature of AFFF foam and

A

Avoid entering the area until a stable Fluoroprotein or Alcohol Resistant Fluoroprotein Foam blanket has been established throughout the area to control the vapors

14
Q

Fluoroprotein Foam can be generated with either

A

Fresh or Salt water

15
Q

Marine companies are issued

A

55 Gallon drums of Fluoroprotein Foam

16
Q

Must be applied continuously while members are in the blanket

19
Q

Fluoropoydol has excellant

A

Burnback resistance and wind and water spray resistance

20
Q

Fluoropolydol is extremely

A

Q
Color Code
Fluoroprotein
Alcohol
Hi Ex
AFFF
A

Brown
Green
Yellow
Black

24
Q

Dry chemical foam must be used to extinguish

A

3D fire

25
Q

Premixing of the Fluoroprotein foam solution can be accomplished by dumping

A

3 - 5 gallon into a 500 gallon pumper or
4 - 5 gallon into a 750 gallon pumper
this will create a 3% solution.
This is only done when a foam eductor cannot be placed into operation. The pumper should NOT be hooked up to a hydrant

26
Q

1st alarm assignment of 3 engines and 2 ladders should provide

A

65 gallons of foam concentrate
Ladders have 2 - 5 gallon cans
Engines have 3 - 5 gallon cans

A

600 SQ FT

28
Q

Foam Carriers

A

10 in service
No water on apparatus

29
Q

Transmit a 10-86 if the incident is

A

beyond the 1st alarm assignment capability

30
Q

Product level must be within

A

5 feet of the top of the tank. If to much product is removed a large “chimney” will form and carry away much of the foam

31
Q

Try to apply the foam in a tank in the “window”

A

The window is an area in the plume which is located on the upwind side of the tank. It is a small area where the flames aren’t as tall. There are less convection currents in this area.

32
Q

1st alarm assignment of foam

A

13 - 5 gallon cans

22 minute duration

33
Q

Steel tanker roll over with leak

A

Shell split likelihood decreased

34

A

May split open

35
Q

A vehicle that has rolled over MUST

A

Be off loaded. NEVER upright

36
Q

What tanks are more likely to BLEVE

A

Steel tanks
Aluminum tanks will melt
Get a LCS on the vapor area. This should be done before, or if enough manpower exists in conjunction with stretching a foam line

37
Q

Have a separate pumper

A

Test and hook up to a hydrant to supply the foam carrier

38
Q

The IC should anticipate that the situation will escalate and that the necessity for a Large Caliber Foam Nozzle exists. In being proactive the following apparatus positioning is necessary

A

1) Satellite apparatus or Tower Ladder if height is an issue to attach the Angus modified foam cannon. Position the apparatus as close as possible to the incident.
2) A 2000 gallon per minute pumper attached to a good source of water is needed for the supply. This apparatus should be as close to the incident as possible
3) Determine a foam assembly point for the foam carrier apparatus or tender to deliver the foam concentrate. The best placement for this is at an intersection where units can come in from one direction and leave by another. This Foam Assembly Point and direction of access should be relayed to the dispatcher for transmittal over the department radio. A BC preferable a Foam Coordinator should be assigned this duty

39
Q

Jet A fuel is a

A

Kerosene based fuel

40
Q

PAPD uses large quantities of

A

AFFF Foam

41
Q

One of the priorities of the FDNY at a airport plane crash is

A

Water supply to PAPD crash trucks

42
Q

If operations are going to involve firefighters working in the vapor area of the airplane crash with fuel present, it is imperative to

A

Apply a Fluoroprotein or Alcohol Resistant Fluoroprotein Foam blanket ovet the AFFF foam blanket produced by the PAPD

43
Q

If an airplane crashes anywhere but at an airport the PAPD

A

may or may not send a crash truck response. In order for the airport to stay open they need a minimum amount of crash trucks to stay open

44
Q

All of NYC Bulk Oil Facilities have a

A

Fire protection system in place. Our 1st consideration is to supply this system with what is needed. Some systems need water and some systems need foam

45
Q

It is important to get at least one TL

A

As close to the tank as possible. If possible leave access for a Satellite

46
Q

A tank that is full will act as a

A

Heat Sink and will not be as dangerous as a tank that is partially full

47
Q

A tank full of vapors is

A

Much more dangerous than a tank full of product

48
Q

Use water on a tank only

A

When it is Steaming. When the tank stops steaming shut down the line

49
Q

Sometimes there are small tanks located in the

A

Dike area that are used for additives to the fuel, vapor recovery units, etc. Many of these tanks are pressurized.

50
Q

The identifying clue to recognizing a pressurized container is the

A

Rounded Ends. These MUST BE COOLED

51
Q

If any tank that is exposed to heat and the pressure relief valve has activated

A

Monitor the release for intensity. Operate hose lines form the SIDES OF THE TANK. The ends of tanks present a more serious danger if the tank ruptures.

52
Q

If the pressure relief valve increases in noise and/or the flame jet increases in height

A

Withdraw with all but UNMANNED lines. This indicates a serious BLEVE potential

53
Q

The specific gravity of most petroleum products is such that they are

A

Lighter than water and will float on the surface

54
Q

As Foam Carriers arrive they should be staged under the control of a

A

BC, preferably a Foam Coordinator. They should report to a pre arranged Foam Assembly Point and NOT ENTER the facility until called for.

55
Q

Large fire boats carry

A

1200 Gallons of foam concentrate. Additional foam concentrate may be provided utilizing foam bladders capable of holding 1200 and 2000 gallons of foam concentrate. These bladders will have to be filled at the time of the incident
