        SAN DIEGO, Nov. 5, 2008 – As natural gas usage increases in the winter, San Diego Gas & Electric (SDG&E) is stressing natural gas pipeline safety.  Though rare, leaks in natural gas pipelines can be caused by third-party contractors, hidden corrosion or natural disasters, and are highly flammable.

        SDG&E offers these safety tips: 

        • Most natural gas pipelines are buried underground, but only major pipeline routes are marked above ground with high-visibility markers.  These markers purposely indicate only the general – not exact – location of major pipelines usually found where a pipeline would intersect a street, highway or rail line.  However, most lower-pressure lines used to serve residential neighborhoods and businesses are not marked, which is why it’s important to know where they’re buried before digging for any reason. 
        • To ensure safety and to comply with California state law, call Underground Service Alert toll-free at 8-1-1 at least two workdays before digging to have utility lines marked at no cost.  To find out if there are pipelines located in a specific area, visit the National Pipeline Mapping System Web site at www.npms.phmsa.dot.gov.
        • Be aware of a “rotten egg” smell – the odor additive in natural gas to help identify leaks – or a hissing, whistling or roaring sound, as well as dead or dying vegetation, near a pipeline.

        If a leak is suspected:

        • Stay calm.
        • Don’t light a match, candle or cigarette, and don’t turn any electrical devices on or off, including light switches.
        • Leave the area where the leak is suspected and call SDG&E immediately at (800) 411-7343 or call the local fire department.
