3.0 SAFETY
WARNING
Water is a conductor of electricity. Application of water and/or foam solutions on energized
electrical equipment can cause injury or death by electrocution. The amount of current that may
be carried back to the nozzle will depend on the following factors:
• Voltage of the line or equipment
• Distance from the nozzle to the line or equipment
• Size of the stream
• Whether the stream is solid or broken
• Purity of the water
The Fire Fighter and Electrical Equipment, The University of Michigan Extension Service, Fourth Printing 1983. Page 47.
WARNING
Risk of electrocution! Penetrating a wall or barrier may place the Nozzle System in direct
metal to metal contact with electric wiring and equipment which can cause injury or death by
electrocution. The nozzle and water are both conductors of electricity. Assume that all wires are
energized at lethal levels. Always disable electric service prior to penetrating hidden spaces.
WARNING
If nozzle gets out of control or away from operator, retreat from nozzle immediately. Do not
attempt to regain control of nozzle while fl owing water. Injury from whipping can occur.
WARNING
Walking on weakened roofs, fl oors, and decks increases risk of falling thru the structure to
areas below which may be engulfed by fl ame. Exercise sound judgement when operating on
questionable surfaces.
WARNING
Large amounts or pieces of debris can reduce the fl ow of the nozzle resulting in an ineffective
fl ow. In the event of a blockage, it may be necessary to retreat to a safe area, uncouple nozzle
and remove debris.
CAUTION
Water streams are capable of injury and damage. Do not direct water stream to cause injury or
damage to persons or property.
CAUTION
Nozzle reaction will vary as supply conditions change: such as opening or closing other nozzles,
hoseline kinks, changes in pump settings, etc. The nozzle operator must always be prepared in
the event of those changes. Failure to restrain nozzle reaction can cause fi refi ghter injury from
loss of footing and/or stream protection.
CAUTION
Kinks in hose line may reduce water fl ow and cause injury or death to persons dependent on
water fl ow. Avoid tight bends to minimize risk of hoseline kinks.
CAUTION
Quick changes in valve position can cause high pressure spikes due to water hammer and may
result in damaged equipment which could lead to injury or death. Open and close the valve
slowly to avoid water hammer.
4.0 USE WITH SALT WATER
Use with salt water 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 effects of corrosion and is not covered under warranty.
5.0 FOAM USAGE
The Task Force Tips Transformer Nozzle System is suitable for use with Class A foam, especially when hidden hot spots need to be
soaked. Generally, the 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. Always fl ush the nozzle thoroughly with water after foam use.
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.
