Propane
vehicle tanks are constructed from carbon steel under a code
developed by the American
Society of Mechanical Engineers.
A propane tank is 20
times more
puncture resistant than a typical gasoline, methanol or ethanol
tank.
New
propane cylinders are manufactured with a
device that
shuts off the
filling process when the tank reaches 80 percent of its liquid
capacity. This allows for changes in fuel volume caused by
temperature variations without any release of gas from the tank.
Propane
engine fuel systems are fitted with safety
devices and shut-off valves that
function automatically if the fuel line ruptures.
Propane
has the lowest
flammability range of
any alternative fuel.
Propane
leaks
are easily detected because
an odorant (ethyl mercaptin) with a scent similar to rotten eggs
is added as a safety measure.
Propane
is a nontoxic,
nonpoisonous fuel that
doesn't contaminate aquifers or soil.
Unlike
gasoline and alcohol fuels, propane
can't be ingested because
it is stored in a closed container under pressure. It vaporizes
internally when released from its container.
Propane
with air won't ignite unless the source of ignition reaches at
least 940 degrees Fahrenheit. In contrast, gasoline's source of
ignition must reach only 430 to 500 degrees Fahrenheit before
igniting.
If
propane gas leaks, it doesn't puddle; it
readily dissipates into the air.
The
propane industry offers an award-winning preventive maintenance
program called GAS
Check® (Gas Appliance System Check). Trained technicians
inspect entire propane systems and appliances to
ensure they are running safely and efficiently,
so consumers can save money and enjoy a healthy environment. The
program also educates homeowners on the proper maintenance of
propane appliances and how to avoid potential health hazards.
The
Certified
Employee Training Program (CETP)is a nationally recognized
training
program for people involved in the handling of propane, equipment
and appliances. The CETP program is being used extensively
throughout the country and is continually expanded and updated.
