Cause of Duke explosion still under investigation


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.
