Another example...

A propane truck cautions that it carries "inflammable liquid".
A dynamite truck cautions that it carries "explosives".

>>Propane is not an explosive???  Go back to elementary school young man.
Or,
>>at least back to basic Jr.  High chemistry!  Propane IS an explosive.  My

If
>>you are still not convinced, turn on the gas (propane) to your barbecue
for a

should

That

with
