Webster's definitions:

Explosive: relating to, characterized by, or operated by explosion (a large-scale, rapid, or spectacular expansion or bursting out or forth)

In short, it's flammable if it can easily be set on fire. It's explosive if the combustion results in a large/quick expansion of volume.

Section 3 of the MSDS states: "Extremely flammable liquified gas".

Section 5 states: "exposure to fire may cause containers to rupture/explode"

Ok, so when propane burns, it doesn't expand quickly in volume, but it does expand. (the section 5 note probably applies to all tanks anyways). We certainly wouldn't want a propane tank to rupture.

So the fire dept must have opened the tank to let some pressure out (hey look, they did!).

Again, in all fairness, there is a very narrow range of conditions required to light up propane. Even when it is lit, it will not rapidly expand in volume.

Here's an example of how to light up propane (beyond the torch...).
Yeah. I thought of a scenario.
You leave a 50lb tank of propane in your garage. All entrances are closed...and you didn't close the valve all the way.
The propane would leak out and fill the garage, while mixing with the air in the garage. Now it is extremely dangerous. All you'd have to do is walk out and "*snif* smells like propane out here.....I think I need a smoke....*BOOM* "
Then that would cause an explosion...but the same would happen if you left an open can of gasoline in your garage.

Like Bigben said....I don't wanna get on the forums one day to find someone 'sectioned' off part of their house cause they weren't taking the propper safety precautions.
