Platform Safety EEC-0061 V1.1
Platform Safety

As required by the hoisting equipment ASME B30 volume.

Inside the personnel platform.

At any platform motion control station.
D. Some operations may require additions to, or modifications of standard signals.

Any special signal shall be agreed upon and understood by the signalperson and
the hoisting equipment operator.

Special signals shall not conflict with the hoisting equipment standard signals.
E. If communications between the operator and platform occupants are disrupted, all
operations shall be stopped until communication is reestablished.
F. If radios or other electrical means of communication are used, they should be
operated on a secure channel.
G. Proper performance of communications shall be verified prior to each lift if radios or
other electrical communication devices are used.
Lifting Personnel Near Electrical Power Lines
Lifting personnel near electrical power lines is not allowed unless there is no less
hazardous way to do the job. Lifting personnel where the hoisting equipment or platform
can be electrified from electric power lines is an extremely hazardous practice.
It is advisable to perform the lift so there is no possibility of the hoisting equipment, load
line, or personnel platform becoming a conductive path.
This hoisting equipment shall not be used to lift personnel under, beside, or over
electric power lines if any combination of boom, personnel platform, load line, and
machine component will enter the prohibited zone as specified in the MINIMUM
CLEARANCE REQUIREMENTS table or the clearances as dictated by applicable
governmental regulations.
Inspection
The platform shall be inspected by a qualified person prior to initial use at each
new job site according to items listed in the “Personnel Platform Pre-Lift Inspection”
