Contractor Killed at PGE's River Mill Dam; Energy-Control Procedures in Question

A contractor was killed during equipment testing at Portland General Electric's River Mill Dam in unincorporated Clackamas County, Oregon, on the afternoon of May 14. He was pronounced dead at the scene despite lifesaving efforts. One PGE employee was also injured and taken to a hospital.

According to Estacada Fire, crews "were unable to reach the contractor until the power at the facility was secured" — by which point resuscitation was no longer possible.

That detail is the center of the case. Oregon OSHA has been notified and will investigate; the Clackamas County Medical Examiner's Office is also reviewing the death.

Why "securing power" matters

When first responders cannot approach a fallen worker until a facility's power is shut off, it points to the central question in this kind of fatality: was the equipment de-energized before the worker was exposed to it?

The controlling rule is hazardous-energy control — "lockout/tagout." Federal and Oregon OSHA standards require that any machine or system capable of unexpectedly energizing or releasing stored energy be locked out and verified at zero energy before a worker is exposed to it. The standard exists precisely so that a worker is never the thing standing between a live system and a restart.

The article reporting the death notes the sequence "raises immediate questions about whether adequate energy control procedures were in place." Whether procedures existed, were followed, and were adequate is what investigators will determine. No findings have been released.

What investigators will examine

• Whether the system the contractor was testing had been locked out and verified at zero energy
• The written energy-control procedure for the task and who authorized the work
• The coordination between PGE staff and the contractor's crew
• Training and qualification for the specific testing being performed

The worker's name and employer have not been released, and no officials have been quoted on the cause.
