Real Transport Safety Issues
While I am sure that Norm Cohen is getting tired of the thrashings from
RADSAFE folks, he needs to understand that what solicits these responses is
the seeming disingenuous "safety concerns" that those of his ilk raise.
Until DOT requires that LNG/Propane travel in Type B containers (as they do
with spent nuclear fuel, HLW and TRU waste), perhaps Mr. Cohen should direct
his energies/concerns to that arena. The excerpt to follow, from the EPA
link given, should have "Salem Unplugged" pulling their own plug and turning
their attention to LNG tankers. From the EPA:
"SUPPLEMENTARY INFORMATION:
I. Background On September 8, 1996, more than 35,000 gallons
of propane were released during a delivery at a bulk storage facility in
Sanford, North Carolina. During the unloading of a specification MC 331
cargo tank motor vehicle into two 30,000-gallon storage tanks, the discharge
hose from the cargo tank separated at its hose coupling at the storage tank
inlet connection. Most of the cargo tank's 9,800 gallons and more than
30,000 gallons from the storage tanks were released during this incident. If
this large quantity of propane had reached an ignition source, 125 people
(workers, residents and emergency responders) could have been killed. The
hazards associated with transportation of liquefied petroleum gas have been
demonstrated repeatedly on U.S. highways. In fact, propane releases are the
second leading cause of death in hazardous materials transportation. Between
1990 and 1991, five reported deaths and 695 injuries resulted from propane
incidents in highway transportation. For example, when liquid propane is
released into the atmosphere, it quickly vaporizes into its normal
non-pressurized gaseous form. This happens very rapidly, and in the process,
the propane combines readily with air to form fuel-air mixtures which are
ignitable over a range of 2.2 to 9.5 percent by volume. If an ignition
source is present in the vicinity of such highly flammable mixtures, the
vapor cloud ignites and burns very rapidly (characterized by some experts as
``explosively''). This has occurred a number of times over the years, and
even though the incidents described below were not caused by spills during
lading transfer, they illustrate the grave consequences of a large propane
release when ignition occurs: On July 25, 1962 in Berlin, NY, an MC 330 bulk
transport ruptured releasing about 6,900 gallons of liquid propane. Ignition
occurred. Ten persons were killed, and 17 others were injured. Property
damage included total destruction of 18 buildings and 11 vehicles. On March
9, 1972 near Lynchburg, VA, an MC 331 bulk transport overturned and slid
into a rock embankment. The impact ruptured the tank's shell releasing about
4,000 gallons of liquid propane. Ignition occurred. Two persons were killed
and five others were injured. Property damage included a farmhouse,
outbuildings and about 12 acres of woodland. [[Page 7639]] On April 29,
1975, near Eagle Pass, Texas, an MC-330 bulk transport struck a concrete
headwall and ruptured releasing more than 8,000 gallons of liquefied
petroleum gas. The ensuing fire and explosion killed 16 persons, injured 51,
and destroyed 51 vehicles. On February 22, 1973, 23 tank cars derailed in
Waverly, Tennessee. During wreck-clearing operations, a 30,000-gallon tank
car containing liquefied petroleum gas ruptured. The ensuing fire and
explosion killed 16 persons, injured 43, and caused $1.8 million in property
damage. On December 23, 1988, in Memphis, Tennessee, an MC-330 bulk
transport struck a bridge abutment and ruptured releasing 9388 gallons of
liquefied petroleum gas. The ensuing fire and explosion killed eight persons
and injured eight. On July 27, 1994, in White Plains, New York, an MC-331
bulk transport struck a column of an overpass and ruptured, releasing 9,200
gallons of propane. Ignition occurred. The driver was killed, 23 people were
injured, and an area within a radius of approximately 400 feet was engulfed
in fire."
