Precautions Near Electrical Power Lines
Never operate the boom within 10’ (3 m) of electric power lines carrying up to 50 kV. Add 1’ (305 mm) of
clearance for each additional 30 kV or less (see table on left). Follow OSHA or other guidelines for working
around power lines. Also observe minimum clearance requirements during transport (see table on right).
Do not enter the danger zone (A), unless one of the
following conditions is met:
• An appointed person has confirmed that the electrical
distribution and transmission lines have been de-
energized and visibly grounded at the point of work.
• Insulating barriers (not a part of the boom) have been
erected to prevent physical contact with the lines.
Do not get boom near power lines. Death or serious
injury will occur. Keep required distance between boom and power lines.
Use a spotter.
