UPDATE: Her death has been ruled accidental

A 37-year-old woman died Wednesday after a 2.5-ton air conditioning unit fell on her at Johnson Controls in York, the York County coroner said Thursday.

Jennifer Wright of West York was taken to York Hospital for treatment, but was pronounced dead at 10:07 p.m.

OSHA has an investigator on scene at the plant at 1499 E. Philadelphia St. Johnson Controls had no comment at this time.

Wright was helping to load a 3,200-pound commercial AC unit onto a trailer when it fell, landing on her, said Coroner Pamela Gay. The incident happened at 9:24 p.m.

Spring Garden Township Police said they found the worker had been pinned under a piece of air handling equipment. Several employees were able to free her and began CPR, police said.

Kevin Kilp, director of OSHA's Harrisburg area office, said preliminary information is that the woman was fatally crushed by a load that tipped off a pallet while being lifted and moved. The victim was a temporary worker employed since April 2016 at Johnson Controls by local staffing agency Master Staffing LLC, 1800 E. Market St., York.

OSHA has up to six months to complete its investigation, Kilp said.

OSHA issued this statement:

"Our thoughts are with the family of the deceased worker. This tragic incident serves as a stark reminder that temporary staffing agencies and host employers are jointly responsible for the safety and health of temporary employees. These employers must assess the work site to ensure that workers are adequately protected from potential hazards. It is essential that employers protect all workers from job hazards-both temporary and permanent workers."

An autopsy is scheduled for Friday morning at Lehigh Valley Hospital.
