The operator of a 100,000-pound drilling rig was seriously injured Friday, Aug. 12, 2022, after the rig tipped over outside Oregon Health & Science University, Portland, and pinned the worker inside.

PORTLAND — The operator of a 100,000-pound drilling rig was seriously injured after the machine tipped over outside Oregon Health & Science University on Friday morning, Aug. 12, pinning the worker inside.

The operator, who has not been publicly identified, was extricated from the machine’s cab by Portland Fire & Rescue and taken to a trauma center, department spokesperson Lt. Laurent Picard said.

No one else was injured, Picard said.

The injured worker is an employee of Vancouver-based construction company Pacific Foundation and was working at the site of a hospital expansion project, according to Tim Johnson, general manager of Skanska, the construction and development company behind the project.

Skanska is investigating what caused the rig to tip over, Johnson said in a statement Friday afternoon.

Johnson said Skanska does not have permission to release the name of the worker, who is being treated at the Oregon Health & Science University Hospital.

Portland Fire & Rescue received reports of the rig tipping over just before 10:45 a.m., Picard said.

Construction crew members positioned a jack to lift the rig up and off the worker before fire crews arrived. Fire officials then broke the glass of the cab and extricated the worker, Portland Fire & Rescue said in a statement Friday afternoon.

The extrication took 14 minutes, officials said.
