8.5
Electrocution hazard! If you are operating and lightning
moves into the area, put the boom into the transport position, or another low posi-
tion, and seek shelter until the lightning is gone.
8.6
Crushing hazard! Never, ever position yourself between a
ready mix truck and the pump! Stand off to the side, so the ready mix driver can
see you at all times (Figure 43).
8.7 When backing in ready mix trucks, use clear and concise hand
signals (Figure 43).
8.8
You must avoid hazardous proximity or contact with power
lines under all circumstances. Be sure that you maintain 20 feet (6 meters) of
clearance! The 20 feet (50 feet above 350 Kv) allows room for the movement of
the wires and the boom by wind force, electrical arcing, and human error (Figure
44).
Do not take chances with high voltage; it is the number one cause of fatal
accidents involving concrete pumps!
