6.0 ANCHORING
The nozzle reaction force on the BLITZTAC 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 but is ultimately the responsibility of the user to follow
the direction of the AHJ.
6.1 ANCHORING BY WEIGHT
On surfaces with good traction a person’s weight on the monitor and/or hose may be sufficient to keep the monitor from sliding. This is
highly dependent on the friction of the surface. The ability to keep one or more people’s weight on the monitor is subject to operator
fatigue and may not be as reliable as other methods. Operating at limited flows will also reduce the risk of sliding.
6.2 ANCHORING BY SPIKE HOLDS
The holding ability of the spikes is generally excellent on surfaces like asphalt, wooden and carpeted floors because they allow the spike
to penetrate well. On hard smooth surfaces such as ceramic tile, smooth concrete, marble, terrazzo, or steel decking the BLITZTAC
portable monitor’s spikes may not hold well. Placing the spikes into cracks, expansion joints, 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.
The holding ability of the spikes on soft surfaces such as sand, gravel and mud is generally poor. Other anchoring methods should be
considered.
