Worker injured during rigging activity due to improper lifting plan and equipment use

What happened - icon

What happened?

During rigging in activities, the set-up crew installed tarps, around the rig floor, for weather protection using a mechanical lift system. The work was completed, and the mechanical lift was returned.

The next day the rig crew found one tarp had been forgotten. A lifting plan was developed to hang the last tarp with an individual in a harness using the boom hoist.

As the worker was lifted, the line caught on a hook handle or dog ear at the bottom of the doghouse, wedging the worker underneath it. The worker sustained a broken pelvis.

Why did it happen?

The tarp installation was incomplete, and the temporary lifting plan was not fit for the task.

Boom hoist is commonly used to hoist materials and is not certified for lifting workers.

What did they learn?

  • Confirm and use equipment that is fit for the purpose, even when it means a delay or added costs.
  • A plan for the complete tarp installation and verification should have been in place.
  • Workers should be aware of their right to refuse unsafe work.

Ask yourself or your crew

How can we prevent something like this from happening here?

What are other risks are associated with forklift operations? How can you mitigate those risks at your work site?

What safety recommendations should be included in the operational instructions?

How can we, as a company, implement a practical training plan that focuses on the job position, and make sure pedestrians are safer from forklifts in the future?
