VANCIOUVER , British Columbia, March 5 (UPI) -- A four-alarm fire struck the Port of Vancouver's container terminal, shutting down parts of the city and compelling residents to stay indoors.
A toxic cloud caused by burning trichloroisocyanuric acid, a hazardous compound used in disinfectants, hung over the Canadian port Wednesday afternoon, as fire fighters battled heavy smoke from the Centerm container terminal. An 800-meter (2,600 feet) evacuation zone was prepared.
