KLAMATH FALLS, Ore. — Law enforcement, firefighters, and a HazMat team all responded to a manufacturing facility along Highway 66 on Thursday after employees reported receiving a "suspicious envelope" that may have contained a hazardous substance, according to the Klamath County Sheriff's Office (KCSO).
Deputies from the Sheriff's Office responded to Production Metal Forming Inc. shortly after noon, accompanied by Keno Fire, Klamath County fire District 1, and the Klamath-Lake Regional HazMat Team. The company's building lies just off Green Springs Highway, roughly between Keno and Klamath Falls.
The Sheriff's Office did not reveal what substance was believed to be inside the envelope, but several employees of Production Metal Forming Inc. were brought to SkyLakes Medical Center as a precaution. All of them were later released, the agency said.
The office area of the building remained under quarantine on Friday while an investigation into the substance continued.
"All precautions were taken and it was determined there is no immediate danger to the public however the office portion of the facility is under quarantine during the investigation," KCSO said.
The agency said that it was working with Klamath County Emergency Management, Klamath County Public Health, and all relevant State and Federal partners to continue the investigation.
