I thought some guy on this list who debunked the canned gas issue back
in the *ist-D days. ...
I haven't seen dust problems for some time and have not done any sensor
cleaning other than the built in hypersonics or whatever. But - I use
canned gas on film before scanning. On occasion propellent does blast
out, no matter how careful I am, and the propellent does leave a residue
on the film. It can be washed off but is a PITA if it is on the
emulsion side.

Don't do it, they say, it is instant death for your camera. Sometimes
so stridently that one would think they were having kittens.
But really, how unsafe is it? What is the very worst case scenario?
How about a blast of liquid straight from the can?
I invite you to watch a short 1 minute (very amateur) video. The
white blast at the 15 second mark is a blast from an upside down
canned gas container being unloaded into the mirror box of a Pentax
*istD camera.
The camera suffered absolutely no ill effects from this abuse.
