6. Safety Rules For Job Setup
SETTING UP A TRUCK-MOUNTED BOOM PUMP
6.1
The job setup phase can set the stage for accidents. Taking a few extra
moments to correctly set up the job will improve your chances of having a safe,
trouble-free day.
6.2
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.
6.3
You MUST avoid hazardous proximity or contact with
power lines at all times! Position the machine so a minimum safety distance of
20 feet (6 meters) or 50 feet (15 meters) for power lines carrying more than
350 Kv
is maintained in all boom positions needed to do the job (Figure 13).
Never decrease the safety distance to reach an unsafe area with the boom.
6.4
When power lines are in the area where the boom will be
moving to complete a pour, a dedicated spotter must be employed whose only
job is to warn the operator if the boom comes within 20 feet (50 feet above
350 Kv) of power lines.
The spotter must understand the responsibilities
assigned, and must be able to judge a 20- or 50-foot distance.
6.5
Some jurisdictions may have regulations that exceed the 20-foot rule. Know the
rules in your area. The standard for concrete pump safety states that any time a
boom might encroach upon the safety zone (between 10 and 20 feet) you must
have a special meeting the day of the pour with all those involved; placing crew,
supervisors, operators, spotters, etc.
