UPDATED: 3 Alarm Fire Burns Hazardous Materials at Stanford Hospital Med School

PALO ALTO, CA -- A three-alarm fire Saturday morning in a medical school building at Stanford Hospital in Stanford was extinguished by sprinklers, but not before the fire consumed biohazardous materials in the area, Palo Alto fire officials said.

The fire was reported by fire officials on social media at 7:46 a.m. in a third floor room in the Edwards Building at 300 Pasteur Drive.

Firefighters evacuated the area around the room. The room that caught fire contains biohazardous waste, but whatever hazardous materials were in the room were consumed by the fire, a deputy fire chief with the Palo Alto Fire Department said.

Firefighters worked to determine what hazardous materials were in the third floor room of the Pathology Department, but because the fire consumed the materials, firefighters haven't been able to find out what those materials were and hospital officials haven't been able to tell fire officials yet, Deputy Chief Catherine Capriles said.

No one was injured in the fire, which did not affect any hospital buildings where patients were being treated, but fire officials temporarily closed the hospital's main entrance, and patients and visitors were being directed to enter the hospital through the emergency room entrance on Quarry Road.

The main hospital entrance reopened around 12:30 p.m.

The fire's cause is under investigation.
