Seeing is Believing: Don't Mess with Buried Facilities
The yellow pipe stretching across more than 60 feet is a
16- inch diameter high pressure natural gas line. Attached
are sling ropes for dewatering hoses. The six-inch yellow
gas distribution main on the right side has fallen out of
its trench due to the collapse of the excavation walls. The
man in the center is leaning on a conduit which contains a
25,000 volt electrical circuit.
Shortly after this photo was taken the earth beneath the
trackhoe at the end of the excavation caved in. The equipment
operator reacted immediately and miraculously avoiding falling
into the excavation and on the high pressure gas line.
Word to the Wise: contact the facility owners for assistance
in proper support of exposed facilities. Never sit on, lean
on or use buried facilities for support.
