Crews mop up foam flood that blanketed Martin Avenue in Santa Clara

Cleanup continued Friday after firefighting foam exploded from airplane hangar at Mineta San Jose Airport...  As a concentrate, the aqueous film forming agent is a carcinogen and irritant. It's technically safe in foam form, but San Francisco Baykeeper is worried about wildlife. "It seems reasonable to expect that some of it will make its way into the creeks and the Bay," said Ian Wren, a staff scientist with San Francisco Baykeeper.
