A Boeing contractor spent two days in the hospital late last week after a piece of tooling fell and hit him at the airframer’s North Charleston campus, a company spokeswoman confirmed Monday.

Candy Eslinger, Boeing spokeswoman, offered few additional details about the Thursday afternoon incident.

“The first responders and Boeing EMS were called to the scene immediately,” Eslinger said. “The person was taken to the emergency room, and he was admitted for 48 hours for treatment and observation. He’s been released and he’s home.”

“And as part of our comprehensive safety plan and our internal processes, we’re currently conducting an investigation to determine the cause,” she said.

Eslinger would not give any more information about the contractor or his injuries, citing health privacy law and company policy. Nor would she say where on campus the incident took place, the type of tooling involved or what effect the incident had on production.

She said he had been “performing his normal job duties” as a contractor with PlaneTechs, a large Illinois-based aviation staffing company, when the piece of machinery fell.

A man who answered the phone in PlaneTechs’ workers’ compensation division on Monday declined to comment on the incident. “We don’t talk about the employees or give out statements about them whatsoever,” he said, identifying himself only as Mr. Lewis before hanging up the phone.

Boeing South Carolina has regularly touted the large number of labor-hours on its sites without a lost-time injury. When its Delivery Center opened Nov. 11, the company press release noted the KBR Building Group, which with Turner Construction formed the joint venture that built the major buildings on campus, had worked more than 4.7 million labor-hours without a lost-time incident.

Eslinger said last week’s incident “likely” would qualify as a lost-time incident but said she didn’t know when the last lost-time incident before that one occurred. There are “just over 5,000” people working at the Boeing South Carolina campus, Eslinger said, and safety is a clear company priority.
