Vancouver Fire and Rescue was called to B.C. Place Stadium at 10:43 p.m. Tuesday after a large quantity of diesel fuel leaked from the overflow valve of a tank near the east airlock doors.

Captain Gabe Roder said the leak was quickly stopped and the diesel absorbed. The hazardous materials team “dammed the spill to prevent further leakage to the sewer system," Roder said.

VANOC’s shipping container-sized Aggreko diesel generators are running around the clock outside B.C. Place in case of a power outage. Neither VANOC nor B.C. Place management responded to an interview request before deadline.

The incident was the second in less than a week at the site of the Feb. 12 Olympic opening ceremony. Rainwater that pooled atop the air-supported fabric roof flooded through drainage holes on Jan. 14. The weight of speakers and lights is flattening the 27-year-old roof.
