The federal Office of Occupational Safety and Health Administration said Boeing violated no labor regulations when a worker fell from scaffolding at the company’s North Charleston plant in March and later died.

David Priester, 38, was critically injured after falling from a mobile platform at the North Charleston plant on March 18 and died as a result of his injuries March 29.

Although OSHA found no violations, it made recommendations for safer working conditions on the platforms, including refresher training for employees as well as providing lights for platform control panels.

Boeing has implemented one of the recommendations and will comply with the other as well, spokeswoman Candy Eslinger said.

“The safety and security of all employees is a core value and at the heart of our operation,” she said. “This was a tragic accident, and we remain deeply saddened and affected by the loss of our teammate.”
