Massive Tracy warehouse fire destroys Medline center as sprinklers fail

A massive fire at the Medline Distribution Center in Tracy, Calif., has destroyed the roughly 1-million-square-foot facility. Firefighters faced challenges because the building's sprinkler system did not operate and hydrants had low pressure, leaving the warehouse a total loss. FedEx evacuated its nearby hub safely; winds threatened the neighboring FedEx site and smoke could drift south, though air quality in the area was generally good with precautions recommended for sensitive individuals.
