It would be better to let the pipe be ruined by setting concrete
than to risk injury by ignoring safe procedures. Always use safe practices when
cleaning pipe. Remember, pipeline is replaceable, you are not.
8.28
Never stand on, sit on, or straddle a pipeline while it’s in use, or
whenever it is pressurized. Pipeline wears out with each stroke of the pump. If the
pipe bursts, you want to be to the side of it, not on top of it (Figure 54).
8.29
Do not kink hoses . Kinking will cause the pump to create
maximum concrete pressure. The pump may unkink the hose with force! (See
Figure 55.)
8.30
Never use compressed air to clear a blockage! It is unsafe and
unnecessary. The pump can develop much more pressure than an air compressor.
If the pump pressure can’t move it, air pressure won’t either.
8.31
Crushing/amputation hazard. Do not remove the water box
covers or grates when the machine is stroking (Figure 56). If you must remove the
water box cover (to add water, for example), and there is not a bolt-down grate
over the water box, stop the pump and take the transmission out of gear so the
pump cannot be restarted until you are finished and the covers are back in place. If
a bolt-down grate is installed, you may simply stop the pump from stroking before
removing the water box covers. Replace the covers before restarting the pump.
8.32
Never leave the pump unattended! If a pour requires you to
be away from the pump, an attendant (i.e. laborer, ready mix driver, coworker)
must be designated who knows:
