Example of Leaklist topics:
1. I'm currently looking at two different leak detection
systems for an existing 12" and 6" fuel line that are
approximately 3 miles long. The two systems that we are looking
at are... Does anyone have any thoughts or experiences with either
sytem?
2. Our client is having a problem and I am in need
of a professional opinion. The tanks at the gas station were installed
in 1983 and they are apparently Owens-Corning double walled USTs.
New Calif regulations require secondary containment testing of the
annular
space (i.e. must hold vacuum). When the annular space of the tank
was tested it did not hold vacuum... Does anyone have any theories
why the tanks did not hold vacuum and
why the pump was pulling hydrocarbons? Were FRP USTs built with
a annualar space drop tube to the bottom? What would be the solution
to getting the annualar space to hold
vacuum?
3. Last week some told me he was positive a cell-phone
induced fire was documented in May of 2003 in Arizona. At the risk
of starting a discussion of possible urban legends, can anyone
direct me to a credible new source about this Arizona incident?
In response to question Number 3 above,
4. Neither API nor PEI is aware of any fire at a service station
or oil rig that has been caused by a cell phone anywhere in the
world. Additionally, the link to the MMS safety alert #6, provides
further information that dispels the cell phone myth. MMS hired
an independent third party to conduct an investigation to determine
if a cell phone provided an ignition source in a panel on an off-shore
oil rig. "[I]t was the opinion of the independent third party
testing laboratory that it is unlikely that the cellular phone would
have ignited a flammable mixture of methane or propane under actual
field conditions and that the cause of the flash fire was something
other than the cell phone." http://www.mms.gov/safetyalerts/6.htm
