The not-for-profit Federation highlighted this safety message with a dynamic display at the Lift Safety Zone at the CONEXPO-CON/AGG show in Las Vegas, which illustrated the safe and minimum approach distances that an AWP should be when working near power lines.
The IPAF demonstration at the Lift Safety Zone illustrated two recommended safe distances:
+ 50 feet (15m) + fully extended boom from electrical pylons
+ 30ft (9m) + fully extended boom from cables on wooden poles
These recommended safe distances meet or exceed those specified in ANSI standards and OSHA requirements.
IPAF North America Manager Tony Groat explained, “Operators or supervisors are often not in a position to know the voltage in the power source. Knowing the voltage is essential to determine the minimum approach distance (MAD), which is the safest distance a person who has not had specific training in avoiding electrical hazards should approach ‘live’ overhead cables. The IPAF recommendations are safe distances until the voltage is determined.
“It is possible to work closer to power lines than the IPAF-recommended safe distances, but this should only be undertaken after seeking expert advice from the power supplier and implementing extra safety precautions.”
Sharing findings from IPAF’s accident reporting project and Powered Access Rental Market Reports, IPAF technical officer Chris Wraith said: “In 2013, all seven reported cases of electrocution worldwide occurred in the US, where the AWP rental fleet is estimated at 510,500, which is 54 percent of the world rental fleet.¹ AWPs are probably the safest way of doing temporary work at height, so the onus is on managers and operators to stay safe when working near to power lines/conductors. Electrocutions can be prevented—through proper planning, risk assessment, and management of work at height, including thorough operator training and familiarization.”
