Meaning Of Signal Words; General Information - Task Force Tips ThunderFog series Instructions For Installation, Safe Operation And Maintenance

1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535.6-2006, the definitions of the four signal words are as follows:
DANGER
WARNING
CAUTION
NOTICE

2.0 GENERAL INFORMATION

This manual describes nozzles calibrated at 100 psi (7 bar) and 75 psi (5 bar). Contact factory for data specific to models that
operate with metric flow calibrations.
Thunderfog, Quadrafog and QuadraCup are economical, lightweight, and dependable nozzles. Their rugged construction is
compatible with the use of fresh water (see section 6.0 for saltwater use) as well as firefighting foam solutions. Other important
operating features are:
• Quick-acting pattern control from straight stream to wide fog
• Fixed fog teeth
• Stainless Steel spinning fog teeth available on some models
• Easily flushable while flowing to clear trapped debris
• Quick-change rear valve seat
• TFT's five-year warranty and unsurpassed customer service

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor
or moderate injury.
NOTICE is used to address practices not related to personal injury.
An inadequate supply of nozzle pressure and/or flow will cause an ineffective stream and can
result in injury, death or loss of property. See flow chart on pages 8 - 11 or call 800-348-2686
for assistance.
This equipment is intended for use by trained personnel for firefighting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
Nozzle reaction will vary as supply conditions change: such as opening or closing other
nozzles, hose line kinks, changes in pump settings, etc. Changes in spray pattern or flushing
will also affect nozzle reaction. The nozzle operator must always be prepared in the event
of those changes. Failure to restrain nozzle reaction can cause firefighter injury from loss of
footing and/or stream protection.
If nozzle gets out of control or away from operator, retreat from nozzle immediately. Do not
attempt to regain control of nozzle while flowing water. Injury from whipping can occur.
Water is a conductor of electricity. Application of water solutions on high voltage 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 water1

Improper use of foam can result in injury or damage to the environment. Follow foam
manufacturer's instructions and fire service training to avoid:
• Using wrong type of foam on a fire, i.e. Class A foam on a Class B fire.
• Plunging foam into pools of burning liquid fuels.
• Causing environmental damage.
• Directing stream at personnel.
