Hi Bill,
Yes, I realize that being only an oxidizer that without
fuel, you would not have a combustion type explosion. But as the photo
of the guy's car shows - even the overheated bottle by itself made an
impressive amount of shredded metal out of his car. Like you point out -
a burst water heater can do an unbelievable amount of
damage.
But, I hate to think of what it would have been
like had fuel been available when the bottle burst.
Since the bottle shows no sign of scorching, fairly
clear no combustion took place.
One thing having this happen to back-end of parked car,
another thing to think of it in my airplane.
Not trying to imply
NO2 is not safe handled properly - Its just I just don't need THAT kind
of boost {:>).
