CAMBRIDGE, Mass. -- Building 18 was evacuated for three hours Tuesday afternoon as the Cambridge Fire Department Hazardous Materials team responded to an incident in a fourth floor laboratory. There were no injuries.
Professor Rick L. Danheiser, associate head of the Department of Chemistry, said that at about 1:30 p.m. a graduate student noticed fumes escaping when he was cleaning equipment with water and sounded the call. Danheiser said the nature and the cause of the fumes were being investigated.
Most of the building was reopened at 4:30 p.m, with the fourth floor re-opening about a half hour later.
