Worker falls from height while rigging out

Worker fell while rigging out, as they were preparing to move to a new location.

Lease hand was working on the substructure, folding down wings, when he slipped and fell over the edge approximately 3.5 meters to ground. The worker had crouched down to lift a handrail into place, his hand slipped and he lost his footing.

Worker was attended by onsite medical, and then sent to nearest hospital. Worker sustained a fractured
wrist.

• When lowering (or raising) wings for rig-out, fall protection was not worn.
• There was no engineered fall protection system on substructure.

Contributing factors:

• JSA and site assessments did not outline all task steps or the need for fall
  protection.
• Fall protection plan did not identify anchor points, or the requirement for fall
  protection for specific equipment or fall protection training.
• Pre-job did not specify consistent working at height requirements.

• Owner will be reviewing all working at height requirements.
• Review of work plan, JSA for rigging in and out, revising pre-job hazard assessment and communicate to site workers.
• Company will improve enforcement of Life Saving Rules and fall protection policy.

• How can something like this happen here (e.g. on our site)?
• What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
• How do we know the risk controls/barriers are working?
• What improvements or changes should we make to the procedures, controls/barriers or the way we work?
