SECTION 302.002 TASK FORCE TIPS
PURPOSE
The purpose of this procedure is to provide Fresno Fire Department (FFD or
Department) members information, operational principles, and technical data
necessary to properly supply and use Task Force Tips automatic and smooth bore
nozzles.
APPLICATION
Task Force Tips automatic and smooth bore nozzles are used by the Department to
flow water from hand lines.
OPERATIONAL POLICY
This section intentionally left blank.
OPERATIONAL GUIDELINE
Members operating the Task Force Tips nozzles should be familiar with the basic
operation and flow capabilities of each nozzle. For recommended pump discharge
pressures, refer to Training and Equipment Manual, Section 303.005, Pump
Operator’s Guide.
PROCESS
The valve handle operates the slide valve or ball shutoff portion of the nozzle. The
valve handle has detented flow positions. These detent positions allow the nozzle
operator to regulate the flow of the nozzle depending on the situational need.
1. How the valve handle operates:
• Pull back on the valve handle to open.
• Push forward on the valve handle to close.
• Close valve handles slowly to prevent water hammer.

2. The nozzle has a full pattern control from straight to wide fog as follows:
• Turning the stream shaper clockwise (as seen from the operating
position behind the nozzle) moves the shaper to the straight
stream position.
• Turning the shaper counterclockwise results in an increasingly
wider pattern.
Since the stream trim point varies with flow, the stream can be “trimmed” after
changing the flow to obtain the straightest and farthest-reaching stream. Properly trim
the stream as follows:
1. Open the pattern to narrow fog.
2. Close the stream to parallel to give maximum reach.
If equipped with a debris screen, small debris pass through the screen and may
become trapped inside the nozzle. This trapped material can cause poor stream
quality. The nozzle can be flushed by using the following steps:
• Rotating the shaper counterclockwise to the flush position while still
flowing. This opens the nozzle allowing debris to pass through.
.
• Rotating the shaper out of flush to continue normal operations.
