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 water 2

Fire streams are capable of injury and damage. Do not direct water stream to cause injury or
damage to persons or property.
Do not couple aluminum to brass. Dissimilar metals coupled together can cause galvanic
corrosion that can result in inability to unscrew threads or complete loss of thread
engagement.
The nozzle may become damaged if allowed to freeze while containing water. Always drain
after use to avoid damage and possible loss of use.
Nozzle must be mated to a hose line with matched threads. Mismatched or damaged threads
may cause nozzle to leak or uncouple from hose under pressure and could cause injury.
This equipment is intended for use by trained personnel for fi refi ghting. Their use for other
purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
