Those compressed air things

If you spray those cans of compressed air and some of the liquid sprays out onto your components, can it do damage? How long should you wait for it to dry til you can turn on your computer again?

Also this might be retarded, but is there any particular reason one shouldn't use a hairdryer, set on cool, to help remove dust? Does the high EMFs it emits pose any danger to the components?
 
Hair driers generate quite a bit of static. The liquid should evaporate almost immediately. IAC, I don't think it's very conductive...

The main concern if you spray liquid contents out of one of these pressurised dusters is crazing damage to plastic finishes.

It will not damage electrical components. As a matter of fact, many techs will use a similar agent to identify defective parts by chilling them while running!

Cheers!
 
The biggest problem that the liquid can cause is condensation, and even that generally will dry up pretty quickly too.

Another use for that liquid - got a nasty insect or spider, like a wasp or something along those lines, in the house that you don't want to squish and get bug guts everywhere? Give it a blast with the liquid. Hit it quick to chill it a little and slow it down, and then blast it good. It'll be frozen solid in no time flat. That stuff evaporates very quickly, and freezes things to less than -22C(-8F); I don't know how low exactly, as this thermometer I have doesn't go any lower.
