3.5 USE WITH FOAM
Nozzles may be used with foam solutions. Refer to fi re service training for the proper use of foam.
WARNING
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; Keeping clear
path to deliver foam as hoses, other equipment and vehicles are deployed.
WARNING
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 fuels; Causing environmental damage; Directing
stream at personnel.
WARNING
There is 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.

3.3 NOZZLE COUPLINGS
Many inlet couplings such as NH (National Hose) or NPSH (National Pipe Straight Hose) can be specifi ed at time of order.
CAUTION
Nozzle must be mated to a discharge with matched threads. Mismatched or damaged threads
may cause nozzle to leak or uncouple under pressure and could cause injury.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability
to unscrew the threads or complete loss of thread engagement over time. Per NFPA 1962, if
dissimilar metals are left coupled together an anti-corrosive lubricant should be applied to the
threads. Also the coupling should be disconnected and inspected at least quarterly.
Dissimilar metals coupled together can cause galvanic corrosion that will freeze the threaded joint or cause complete loss of thread
engagement. If dissimilar metals must be coupled together, the eff ects of corrosion can be greatly delayed by various coatings on
the metal such as powder paint, hard anodizing, or silicone grease.
3.4 USE WITH SALT WATER
Use with saltwater is permissible provided nozzle is thoroughly cleaned with fresh water after each use. The service life of the nozzle
may be shortened due to the eff ects of corrosion and is not covered under warranty.
