Advancing With A Charged Hose; Anchoring; Anchoring By Weight; Anchoring By Spike Holds - Task Force Tips BLITZFIRE Series Instructions For Safe Operation And Maintenance

5.3 ADVANCING WITH A CHARGED HOSE

On a charged hose the Blitzfi re may be advanced by holding the valve handle and one of the legs as shown in fi gure 5.3. Valve
handle should be locked in the closed position to keep the valve from inadvertently opening.

6.0 ANCHORING

The nozzle reaction force on the Blitzfi re Portable Monitor may be as high as 330 lbs - 500 GPM at 175 PSI (150 kg- 2000 LPM at
12 BAR). This nozzle reaction must be restrained to keep the monitor from moving.
The monitor should be anchored from moving by one or more of these methods:
Hooking legs on vertical surfaces

6.1.1 ANCHORING BY WEIGHT

On surfaces with good traction a person's weight on the monitor and/or hose may be suffi cient to keep the monitor from moving. This
is highly dependant on the friction of the surface. The ability to keep one or more than one person's weight on the monitor is subject
to operator fatigue and may not be as reliable as other methods. Operating at limited fl ows will reduce the risk.

6.1.2 ANCHORING BY SPIKE HOLDS

Anchoring by spike holds is defi ned as intentionally placing
one or more spikes into a crack, hole, or other hold to anchor
the monitor from moving. On hard smooth surfaces such as
ceramic tile, smooth concrete, marble, terrazzo, or steel decking
the Blitzfi re's spikes may not hold well. Placing the spikes into
cracks, expansion joints, or gratings or the like will help hold the
monitor from sliding. Even with the spikes anchored, sliding may
be caused by the surface cracking under the load, or from the
hose or nozzle moving the monitor thereby dislodging the spikes
from their hold. Figure 6.1.2 shows a close up of a spike caught
in a crack.
The holding ability of the spikes on soft surfaces such as sand,
gravel and mud is generally poor, therefore other anchoring
methods should be considered.
