A chemical explosion Wednesday night prompted fire officials to evacuate a 64-unit building at the Shorewood Apartments, 5555 E. Evergreen Blvd.
The incident at 7:35 p.m. occurred when a maintenance man was using chemicals in a maintenance room next to the basement swimming pool, said Jim Flaherty of the Vancouver Fire Department.
Two hazardous-materials technicians were called to investigate and firefighters were working to ventilate three floors that house about 110 people.
The maintenance man was reportedly hurt, with a cut on his head, and was taken to a local hospital. No other injuries were reported.
