A cloud of black smoke loomed over the Haas School of Business on Monday morning as Oakland firefighters responded to a three-alarm fire on the 2000 block of Solano Way about 8:30 a.m.
The fire, which was contained to the American Emperor warehouse near the intersection of East 12th Street and 19th Avenue in Oakland, sent plumes of smoke into the air that were visible from San Francisco, Berkeley, Lake Merritt and the Marin Headlands, according to Twitter users.
American Emperor is a supply store that provides plumbing, electrical, lighting fixtures, HVAC and building material supplies. Founded in 1983, the company has six spaces in Oakland, San Francisco, San Jose, Concord and Orange.
The cause of the fire is currently under investigation.
