What happened?
A cherry picker was being used for making up a casing spear.
The cherry picker hit a stand of drill collars in the aft setback area.
The vibrations caused a 0,76kg metal sign to break off.
The sign fell 8m(26ft) to the drill floor, inside the exclusion (red) zone.
Thanks to good practice, no workers were in the red zone while the cherry picker was moving, so no one was injured.

Why did it happen?
The sign was in an exposed position and likely to hit stands in the aft setback area.
The sign had not been recorded in the DROPS register as a risk.
Although it had no functionality, the sign had not been removed.

What did they learn?
Review the DROPS manual to identify potential risks onsite.
