SAN FRANCISCO --
A boiler at an abandoned power substation fell during a demolition project Monday, killing a worker, seriously injuring another and leaving firefighters scrambling to free a third who was trapped.Crews were working to reach the trapped person, Fire Department spokeswoman Mindy Talmadge said. The area surrounding the building was strewn with debris, and about a dozen emergency vehicles were lined up around the site.
Pacific Gas and Electric Co. spokesman David Eisenhower said he could not immediately provide any details about the accident or the building. He said the power plant recently was decommissioned.
"Our first concern, our main concern, is with the welfare of the folks out there," Eisenhower said.
