Nitrous bottles are WAY above 1000psi. Last year I saw some pictures on the
web of a bottle explosion apparently caused by a defective (wouldn't shut
off)
bottle heater blanket and the failure of the safety valve on the tank to
vent properly.
The car (I think it was a Maxima) was in a garage. The car was turned into a
pile of
scrap metal, with a large porion of the trunk area blown out through the
garage
door into the front yard and the garage wall was knocked off the foundation.
no-one
hurt, but close call. Speculation put the bottle pressure at around 3000psi
or
more when it blew. They are generally safe, but, like any high pressure
bottle
they have their potential hazards. I think they should be removed from the
car
and stored, subject to the same rules as welding rigs, which are in the
2000psi range.
This eliminates the possibility of the driver hooking it back up after tech.
I don't think the bottle should be in the car when it runs.

Section 1.4.L: "Pressurized gas and air bottles with a pressure in excess of
200 psi must have a protective structure around their gauge and valves."
Clearly the intent is to address nitrogen bottles and welding rigs. I am not
sure how much pressure a NOS bottle has, I bet something considerably less
than 200 PSI. Further to that, in the even of an explosion, I would rather
that bottle be secure in the trunk of a car then laying loose unprotected.
Now my whole caveat to this deal is this: the bottle would have to come out
the car if somebody showed up and the bottle was in the hatch of a hatch
back, say CRX or such. The bottle is best protected, and we are best
protected from it like a fuel cell and a battery, when enclosed in some type
of metal structure.
