6.0 USE WITH FOAM

The nozzle may be used with foam solutions. Refer to fi re service training for the proper use of foam.

6.1 FOAM ASPIRATING ATTACHMENTS

Multi-expansion or low expansion aspirating attachments may be used with nozzles to increase the expansion ratio. These foam
tubes attach and detach quickly from the nozzle. As expansion ratio is increased, the reach of the nozzle will be decreased due to
the greater amount of bubbles in the stream and their ability to penetrate the air. Generally the straight stream reach with foam is
approximately 10% less than with water only. Actual results will vary based on brand of foam, hardness of water, temperature, etc.
For specifi c information, see LIA-025 (MANUAL: Foam Attachments for TFT Nozzles).

7.0 USE OF NOZZLES

IT IS THE RESPONSIBILITY OF THE INDIVIDUAL FIRE DEPARTMENT OR AGENCY TO DETERMINE PHYSICAL CAPABILITIES
AND SUITABILITY FOR AN INDIVIDUAL'S USE OF THIS EQUIPMENT.
Many factors contribute to the extinguishment of a fi re. Among the most important is delivering water at a fl ow rate suffi cient to absorb
heat faster than it is being generated. The fl ow rate depends largely on the pump discharge pressure and hose friction loss. It can be
calculated using a hydraulic equation such as:
PDP = NP+FL+DL+EL
PDP = Pump discharge pressure in PSI
NP = Nozzle pressure in PSI
FL = Hose friction loss in PSI
DL = Device loss in PSI
EL = Elevation loss in PSI

8.0 APPROVALS

Many nozzle confi gurations carry the FM Approval rating, NFPA certifi cation, or EN certifi cation.

9.0 COLOR CODED VALVE HANDLE AND PISTOL GRIP

TFT nozzles with lever type valve handles are supplied with black valve handle covers and pistol grips. The handle covers and pistol
grips are available from TFT in various colors for those departments wishing to color code the nozzle to the discharge controls. A
colored handle cover set will be sent upon receipt of the warranty card by TFT. Your department's name can also be engraved on the
covers (see warranty card for more information).
Handle covers are replaceable by removing the four screws that hold the handle covers in place. Use a 3/32" allen wrench when
replacing screws. Pistol grip is replaceable by following TFT instruction sheet LTT-108.
For standardization NFPA 1901 (A-4-9.3) recommends the following color code scheme:

For Class B fi res, lack of foam or interruption in the foam stream can cause a break in the foam
blanket and greatly increase the risk of injury or death. Assure that:
• Application rate is suffi cient (see NFPA 11 or foam manufacturer's recommendations)
• Enough concentrate is on hand to complete task (see NFPA for minimum duration time
requirements)
• Foam logistics have been carefully planned.
Allow for such things as:
• Storage of foam in a location not exposed to the hazard it protects
• Personnel, equipment and technique to deliver foam at a rapid enough rate
• Removal of empty foam containers
• Clear path to deliver foam, as hoses and other equipment and vehicles are deployed
Improper use of foam can result in injury or damage to the environment. Follow foam
manufacturer's instructions and fi re service training to avoid:
• Using wrong type of foam on a fi re. i.e. Class A foam on a Class B fi re.
• Plunging foam into pools of burning liquid fi res.
• Causing environmental damage.
• Directing stream at personnel.
There are a wide variety of foam concentrates. Each user is responsible for verifying that any
foam concentrate chosen to be used with this unit has been tested to assure that the foam
obtained is suitable for the purpose intended.
Use of compressed air foam (CAF) with hand held nozzles can cause sudden surges in nozzle
reaction force resulting in risk of injury or death from loss of footing or hose whipping. Be
prepared for sudden changes in nozzle reaction caused by:
• Slug loading (Loss of foam concentrate sends slugs of air and water into the nozzle)
• Sudden release of built-up pressure in the hose when opening a nozzle
