Mike S., you may be the guy to back this up -- as I recall, propane gas is
*heavier* than air, so any leakage would not disperse into the air, but
would instead hang at ground level waiting for the next ignition source?

Yes! exactly. Anne Lurie

That is what is explained in my last post. Reposted below. It will act
just like the gasoline.
I said this will take place using the gas at 110#'s but, it can happen
at any pressure.
It stands to reason that the more gas, the bigger the
KAAABOOOOMMMMM!!!!!!!!!!!!!!!!!!!!!1

Repost:

It is EXXXTREMELY DANGEROUS, and at that pressure it will not ignite at
first, but when the mixture 10 to 20 feet away gets to the proper
proportions, and you attempt to light it. It will ignite.

But the results will be a fireball of disastrous proportions. It will
blow like a quart of gasoline that was tossed on the ground and lit 30
seconds later. A big WOOSH, FIREBALL, and a FLASHOVER across a very
large area.


I thought I read about a worst-case scenario of propane gas back in the mid
80's when I lived in New Jersey. It was apparently illegal for movers to
transport filled propane [BBQ] tanks, so soime idiot simply opened up the
valve to let the propane out. The gas, being heavy, simply flowed along the
ground until a neighbor unknowingly ignited his own BBQ -- and, foom! At
least one child was seriously burned (to the best of my recollection --
but I'd be unwilling to put this theory to the test).

Like I said before If it wasn't so cold and everything was frozen I
could show some controlled examples.

Propane gas can be used to power products such as:

* Barbeques
* Emergency generators
* Pool heaters
* Clothes dryers

Natural gas is the most common type of gas used in households. It is
used to power household appliances such as:

* Stoves
* Heaters
* Fireplaces
* Clothes dryers

Propane gas, and natural gas are relatively safe if handled in the
appropriate manner. However, if handled improperly, gas can be deadly.

Causes of Gas Fires & Explosions

Some of the more common root causes of gas fires and explosions include:

* Improper handling - people who are not careful when handling
gases are often to blame for gas fires and explosions.

* Failure to follow safety codes - guidelines for the safe use of
gases are issued by the manufacturers of products and by U.S. government
agencies. If these guidelines are not followed there is an increased
risk of gas fire or explosion.

* Defective products - although manufacturers test their products
for safety defects before they are offered to the public, some products
may contain a defect that can lead to a gas fire or explosion. Among
products that can lead to gas fires, propane barbeques are the most
commonly recalled.

* Improper application - people try to create dazzling effects in
their PONDS, without following logical guidelines and advice necessary
to ensure proper operation. If these guidelines are not followed there
is an increased risk of gas fire or explosion. 8~)
