Failure to restrain nozzle reaction can cause firefighter injury from loss of
footing and/or stream protection. 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
positioned to restrain the nozzle reaction in the event of those changes.
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 in section 8.0 or call 800-348-2686 for assistance.
Fire streams are capable of injury and damage. Do not direct water stream
to cause injury or damage to persons or property.
Injury from whipping can occur. 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.
4.0 NOZZLE CONTROLS
On models that use a lever type valve handle, the nozzle is shut off when the handle is fully forward. The valve handle has
six detent flow positions. These detent positions allow the nozzle operator to regulate the flow of the nozzle depending on
the need or what can be safely and effectively handled. TFT recommends the use of a pistol grip for easier handling. For
additional stress reduction, a hose rope or strap may also be used. This permits more effective use and ease of
advancement, while minimizing strain and fatigue.

FIGURE 2
The charts in section 8.0 of this document give specific examples of maximum flow rates for particular situations. Friction
losses may vary due to differences in hose construction resulting in flows different than those shown. For situations or
lengths of hose not listed on the chart, approximate flows can be calculated using conventional hydraulics.
