San Diego Gas & Electric lists precautions to avoid to another San Bruno
In the wake of the San Bruno disaster, the power company in San Diego is warning customers to be vigilant for gas leaks that, while "rare," are highly flammable.
The most telltale sign is a distinctive smell.
But there are other ominous indications -- a hissing, whistling or roaring sound, or mysteriously dead vegetation -- says San Diego Gas & Electric Co., which serves San Diego County and southern Orange County
Other tips: Don't do your own investigation. Call the company: (800) 611-7343.
"No damage is too small to report if a leak is suspected," said the company statement.
Leaks can be caused by corrosion, natural disasters or third-party contractors. Gas lines are not marked for the public. Anyone doing construction or landscaping digging should call 811 for help in avoiding the lines.
