16.3
Electrocution hazard! If the pump or boom becomes energized
with high voltage and you are in contact with any part of it, you are at risk of elec-
trocution! You should monitor the movement of the boom and alert the operator if
the boom comes within 20 feet of power lines (50 feet above 350 Kv). (See Fig-
ure 76.)
16.4
When power lines are in the area where the boom will be
moving to complete a pour, a 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. Use visual aids such as cones to help
the spotter to understand the danger zone. (Figure 77.)
16.5
Keep an eye on the movements of the boom, even when there
are no power lines or other wires nearby. Alert the operator if the boom is nearing
any obstruction or hazard. Where jobsite safety is concerned, two sets of eyes and
ears are better than one.
