What happened?
Workers were changing corroded grating on the process deck level.
The corroded grating was 2 m x 0.5 m (6 ft x 1.5 ft) and weighed 64 kg (141 lb).
The workers lost control of the grating while lifting it.
It fell through a slot in the supporting structure, landing on the main deck 5 m (16 ft) below.
The area below was not barriered off, but nobody was in the area, so there was no injury to any workers.
There was no damage to any other equipment.
-
Why did it happen?
The grating was not tethered to prevent the fall.
The workers did not have the correct tools for the manual handling aspects of the task.
The permit to work (PTW) and task risk assessment (TRA) had conflicting information regarding hazard identification and risk control.
There were not enough experienced workers assigned to the team.
-
What did they learn?
Consider securing or tethering equipment to avoid it being dropped.
Make sure that all drop zones are clearly marked and out of bounds to other workers.
Ensure that all workers have required tools for the task they are going to complete.
Task risk assessments and permits to work should clearly identify the hazards and risks of the task.
Make sure that all teams have enough competent workers assigned to the work.

Ask yourself or your crew
What arrangements do we have in place to control or prevent dropped objects?
What controls do we need to put in place to protect those working below us (e.g. from dropped objects)?
Do you have all the tools you need to complete your task?
Are the hazards and risks clearly identified in the risk assessment or permit to work? What has been missed?
