17.21
Do not allow the boom hose to get lower than two feet above
the deck to prevent the boom hose from hitting the feet of the hose-person, and to
prevent the hose opening from being blocked by the deck, which could cause the
hose to whip.
17.22
Never stand on, sit on, or straddle a pipeline while it’s in use, or
whenever it is pressurized (Figure 96). 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.
17.23
To avoid confusion and conflicting signals, only one person
should act as a signalperson (give operational signals to the pump operator).
However, the operator is trained to obey a stop signal from anyone and everyone.
Before the pour begins, the hose-person, the operator and the
signalperson should agree on hand signals (Figure 97)
