SDG&E Offers Tips for Preventing, Spotting and Responding to Natural Gas Leaks

SAN DIEGO, Dec. 4, 2012

SAN DIEGO, Dec. 4, 2012 /PRNewswire/ --With the winter season here, natural
gas for heating has increased throughout the region. San Diego Gas & Electric
(SDG&E) urges customers to be aware of potential natural gas leaks.

Leaks in natural gas pipelines can be caused by third-party contractors,
hidden corrosion or natural disasters, and can be flammable.

SDG&E offers these safety tips:

  oIf natural gas appliances are used in the home or business, it is an
    indication that natural gas pipelines exist in the neighborhood.
  oMost 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.
  oPipeline markers also do not indicate the depth or the number of pipelines
    in the area. Most lower-pressure lines used to serve residential
    neighborhoods and businesses are not marked, and could be just inches
    below ground, which is why it is important to know where they are buried
    before digging for any reason.
  oCall Underground Service Alert (USA) at 8-1-1 at least two business days
    before digging to have utility-owned lines marked. USA will coordinate
    with SDG&E and other utilities in the area to mark the locations of buried
    utility-owned lines. This is a FREE service and it can help prevent
    injury, costly property damage and loss of utility service. Once lines are
    marked, use only hand tools within 24 inches of each marked utility line
    to carefully expose the exact locations of all lines before using any
    power excavation equipment in the area.
  oBe aware of all the possible signs of a gas leak, including a distinct
    unpleasant smell – the odor additive in natural gas to help identify leaks
    – a hissing, whistling or roaring sound, a ground fire, as well as dead or
    dying vegetation in an otherwise moist area over or near a pipeline.
  oEven though a distinctive odor is added to natural gas to assist in the
    detection of leaks, do not rely on sense of smell alone to alert you to a
    gas leak since there may be occasions when you might not be able to smell
    the odor additive. Visit SDG&E's website at for
    more information.
  oImmediately report any pipe damage by calling SDG&E at (800) 411-7343. No
    damage is too small to report.

If a leak is suspected:

  oStay calm.
  oDon't light a match, candle or cigarette, and don't turn any electrical
    devices on or off, including light switches, or use any device or
    equipment that could cause a spark.
  oImmediately evacuate the area where the leak is suspected and from a safe
    location call SDG&E at (800) 411-7343 24 hours a day, seven days a week,
    or call 911.
