Duke University officials say they still don't know what caused a steam line rupture that killed an employee inside a campus building.

Duke's vice president for campus services Kemel Dawkins said Thursday the school is confident its buildings are safe. But he said officials are looking into safety concerns raised by the family of 63-year-old Rayford Cofer.

Cofer died Wednesday when a steam line burst as he worked inside the mechanical room in the basement of a science building. Cofer was a master steamfitter from Franklinton.

No other injuries were reported.

The accident is being investigated by the Occupational Safety and Health Administration. A spokesman said the review could take as many as three months.

The Levine Science Research Center reopened Thursday.
