What happened?
A 165-tonne crane was being moved to a pad for disassembly.
The rear facing upper cab operator saw that the jib could make contact with the plant.
He tried sounding the horn, but this failed to work, so he left the cab to warn the driver.
While crossing the deck, he tripped on a ladder and fell 6 feet to the ground, injuring his wrist and elbow.
-
Why did it happen?
When the horn failed to work, the operator left the cab because he did not have another way of communicating with the driver (e.g. radio).
There were no other spotters in position who could have alerted the crane driver.
Ladders were in their normal storage locations, and caused the operator to trip.

What did they learn?
Field level risk assessments should consider:
- Is there adequate means of communication (radio and signals) between everyone involved?
- Has a thorough hazard evaluation been completed?
- Have hazards associated with moving the crane been planned for and mitigated?
- Are spotters with adequate line-of-sight in position during the operation?
-
Ask yourself or your crew
What other actions could have been taken?
How can something like this happen here?
What means of communication do we have? What else is needed?
What hazards have we not considered (to people, or to nearby equipment or plant)?
Where are the spotter’s/driver’s blind spots?
How would you intervene if you saw this happening?
