Q

Two main categories of foam?

A

HI-EX-CLASS A combustibles– in areas inaccessible like cellars and ship holds- NOT suitable for outdoor flammable liquids

Low-expansion foam- useful on fires and spill involving flammable and combustible liquids

Q

Four primary methods of extinguishment?

A

Smother-prevents air from mixing with flammable vapors

Suppressing- stops release of flammable vapors

Separates- the flame from the surface of the fuel

Cools- water content of the foam cools the fuel further reducing vapor generation

Q

AFFF….(synthetic based(

A
  • spreads over surface for FASTER knockdown of fire than protein based
  • can be used through fog nozzle
  • poor resistance to flashback and burning
  • EXCELLENT for FUEL OIL/KEROSENE AND JET FUEL
  • FDNY use limited to 2 1/2” gallon pressurized water extinguisher with straight bore nozzle

Q

At times Dept. will intentionally apply two different types of Finished Firefighting Foam at an incident…example..

A

AIRCRAFT incidents:

Port authority crash trucks use AFFF, for fast knockdown capability on jet fuels

FDNY UNITS will arrive and may be tasked with overhauling…this could involve entering foam blanket that is floating on jet fuel…a blanket aerated Fluoroprotein or Alcohol Fluoro. foam should be applied

Q

Fire in Confined Area…Tanks/Pits…

imperative that enough foam is on the scene before operation is started

A
  • if there is sufficient freeboard-direct stream and side /back-foam will gently fall over surface
  • if top of container is close to ground and there is little or no freeboard–stream should be directed to ground, bounce foam
  • if tank is filled to top…insure product level is within 5 feet from top

50
Q

Spill contained or not flowing..

A
  • direct foam stream on ground ahead of the fire…BOUNCE FOAM onto fire…this will achieve widest pattern
  • deflect stream against something
  • direct foam skyward
51

52
Q

Spill flowing and NOT contained…

A

-work against run of spill…FLANKS

53
Q

Entries into Foam Blanket shall be limited to?

A

RESCUE of trapped or injured victim

54
Q

Tanker Truck Accident with a leak…

A

once spill is abate and leak stopped, a decision has to be made whether or not to allow the tanker to proceed or to have it loaded ….if you are confident the vehicle can move without the leak starting again , an engine company can ESCORT the vehicle to a loading facility in NYC

55
Q

Tank Truck roll over with a leak…

A

-steel tank-likelihood of split in shell is reduced
-truck will leak around the manhole on the
top.
-MUST be off -loaded…
-NEVER attempt to upright a loaded vehicle

57
Q

Tanker Truck with Fire…

A
  • older steel tanks can BLEVE (newer aluminum..less likely)
  • -when chance of BELEVE exists- extremely important to get LARGE CALIBER STREAM ON THE VAPOR AREA quickly
  • this should be done BEFORE, or after enough manpower is on the scene in conjunction with stretching foam hand line

63
Q

What is our FIRST consideration at Bulk Oil Facilities?

A

to supply FIRE PROTECTION system in place

  • ALL of NYC bulk oil facilities have a fire protection system
  • some need water, some need foam solution and some need foam concentrate

65
Q

Containers with ROUNDED ENDS…?(bulk oil facilities)

A

MUST BE COOLED

  • operate from sides of these tanks
