3.0 GENERAL INFORMATION

The CROSSFIRE monitor is the most rugged and innovative deck/portable master stream device ever offered to the fire service.
Attachment of the CROSSFIRE to the base is quick, easy, positive, and can be visually verified. The release mechanism is locked out by
water pressure. The rotation lock is a simple lever which securely holds the CROSSFIRE monitor in position. An automatic drain allows
water to drain from the monitor when not in use.
A sliding monitor can cause injury. To protect against sliding:
• make sure the base legs are locked in position with all leg spikes in contact with the ground.
• securely tie the monitor to an object capable of withstanding 900 lbs (400 kg) of force.
• use additional tie downs on hard surfaces such as concrete, asphalt, and metal.
• avoid lifting the monitor when moving the hoses around it.
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.
Some volatile liquids can be ignited by static discharge. Static build-up can occur from:
!
Electrochemical separation of charge as water drains through low conductivity, refined
products.
!
Applying foam over a low conductivity liquid of sufficient depth to retain the charge created as
the foam blanket drains.
!
Streaming currents as water or foam is introduced into the storage tank.
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
Master stream flows are very powerful and capable of causing injury and property damage. Make
sure the monitor is securely attached to the base and pointing in a safe direction before water to the
monitor is turned on. Use care in directing the stream.
Nozzle must be properly connected. Mismatched or damaged threads may cause nozzle to leak or
uncouple under pressure and could cause injury.
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.
