Tag lines should always be made of non-conductive materials.
Any tag line that is wet or dirty enough can conduct electricity.
Working in the vicinity of radio frequency transmission towers/sources may cause a crane to become electrically
"charged." Survey the work site and develop specific safety precautions and operating procedures, prior to commencing
operations.
If contact is made with a power source THINK DON'T PANIC.
1. Warn everyone to stay away from the crane.
2. Attempt to free the crane by operating the crane functions.
3. Stay in the crane until the power source has been deenergized.
Only as a Last Resort should an operator attempt to leave the crane upon contacting a power source.
If it is absolutely necessary to leave the operator station, JUMP COMPLETELY CLEAR OF THE CRANE DO NOT STEP
OFF. Hop away with both feet together. DO NOT walk or run.
When operating cranes equipped with electromagnets you must take additional precautions.
-
Permit no one to touch the magnet or load.
-
Alert personnel by sounding a warning signal when moving a load.
-
Do not allow the cover of the electromagnet power supply to be open during
operation or at any time the electrical system is activated.
-
Shut down the crane completely and open magnet control switch prior to connecting
or disconnecting magnet leads.
-
Use only a nonconductive device when positioning a load.
-
Lower magnet to stowing area and shut off power BEFORE leaving the operator's
cab.
Following any contact with an energized electrical source, thoroughly inspect the wire rope and all points of contact with
the crane.
Advise your distributor of the incident and consult the factory for advice and crane inspection instructions prior to
resuming operations.
