Man medivaced after ammonia leak, current health status unknown

Updated | 1:46 p.m.

A man was medevaced from Unalaska on Saturday after suffering serious injuries from an ammonia leak at the Kloosterboer cold storage facility.

Police Deputy Chief Jennifer Shockley said the man was inside an industrial freezer when its ammonia line began leaking.

After he was “extricated and decontaminated,” the man was flown to Anchorage for emergency treatment. His current medical status is unknown, but Shockley said ammonia poses significant health hazards.

“It can cause a burning sensation on any exposed skin,” she said. “Mucus membranes are also affected by it — your mouth, nose, and lungs.”

Thirteen emergency responders and a seven-person hazmat team responded to the incident Saturday at 12:45 p.m. Shockley said they quickly contained the leak inside the freezer, but she didn’t know how long it took to shut off the ammonia supply entirely.

The responders — from the Unalaska Department of Public Safety and the UniSea hazmat team — were on-scene for more than six hours, ventilating the building and keeping the area outside clear of people. Shockley said they deemed the facility safe to enter without breathing aides about 10 a.m. Sunday.

Police are now investigating the cause of the leak.

“We’ll have an investigator looking into it — basically, documenting what happened and getting statements from people,” Shockley said. “Not because we think there’s anything criminal, but because the time to do an investigation is when an incident happens.”

Another person suffered minor injuries during the leak, but he did not require medical treatment at the clinic.

Officials at Kloosterboer did not immediately return calls seeking comment.
