7. Setting Up A Trailer-Mounted Pump and/or A Separate Pipeline
7.1
The job setup phase sets the stage for most accidents. Taking a few extra
moments to correctly set up the job will improve your chances of having a safe,
trouble free day.
7.2
The operator is responsible for the safe operation of the machine . Notify your
employer, the job superintendent, and/or O.S.H.A. if you are being asked to set up
in an unsafe manner.
You are never required to take a chance with safety. You
are the only person who can determine that the job circumstances under your con-
trol are safe.
7.3
Any power connections above 28 volts must be made by a
licensed electrician. The supply power and appropriate disconnect boxes are the
responsibility of the contractor.
7.4
Electrical power on the job site may be taken only from a
fused, grounded disconnect box with a disconnect switch that can be locked
against activation.
If you will be making repairs to the concrete pump or separate
placing boom, first lockout the power at the disconnect box .
7.5
On units equipped with electric motors, check the power
cables every day. If they are frayed or have open spots in the insulation, or if the
connectors are worn or loose, have repairs made by a licensed electrician.
7.6
Consider the safe approach and departure of the ready mix
trucks and adjust your setup accordingly. Adjusting your setup position by a
few degrees one way or another could mean the difference between a safe
approach and an unsafe approach. Some examples of unsafe approaches are: too
near an excavation or sticking out into traffic.
7.7
Avoid collisions! Secure the immediate area of the machine
from public traffic in accordance with all applicable regulations (warning lights,
safety cones, barricades with flashers, etc.).
7.8
Pipelines, end hoses, couplings, and all other material delivery
components must be able to withstand the maximum concrete pressure of the
pump.
Be sure of it! Read and understand the minimum wall thickness chart
found in the Appendix of this Safety Manual . If you don’t understand the chart,
contact the pipe manufacturer for assistance.
7.9
Do not use a piece of pipeline, end hose, coupling, or any other
material delivery component that is not in good condition. Replace—do not
repair damaged pipes and hoses. Concrete pipeline system is subject to wear,
and the rate of wear is affected by pumping pressure, concrete composition, pipe-
