canned air, a warning
« on: October 04, 2012, 02:11:59 PM »
So, working from home today...new job allows me to do so 3 days a week...and I'm on a conference call...my computer fan starts making a lot of racket so I mute the call, pop the side off, and grab the canned air...can't quite reach the fan, so not thinking I point thenozzleupwards, thus releasing the liquid...no, the cold didnthurt the computer, but aparrently something was hot enough to ignite the damn liquid/gas...big bellybutton fireball shoots out of my PC...it immediately went out gut left behind a horrible smell, and caused me some lung irritation...still coughing up gunk from it....needless to say,I will NOT be using that crap any more..and I advise noone else to do so either..

Canned air for electronics is fine if used correctly. Lucky you did not catch something on fire. :)

Yea, it was definitely a bonehead move, and not one I will repeat...glad no fire, this lung and throat irritation is bad enough....that's OK though, gave me an excuse to finish working from my deck :-)

For the throat irritation I suggest a glass of milk.

The man has a cough shuffler.  This requires cough medicine, and l,m sure a.stressful situation, and is recuperating at home.  Dewars or jack daniels should be appropriate.   :cheers:

Phase changes aren't just a function of temperature but of temperature and pressure.

Increasing pressure [Y axis] at constant temperature makes substances go from gas to liquid to solid. This chart is for CO2 but a (halo)alkane like from what I understand 'canned air' is is going to look the same, just with different values.

p.s. chemistry is the best science

Milk coats. It is also suggested for folks who eat a hot pepper and can't handle it.

Glad to hear you got some relief.

That there is a darned good answer Motherland.
Now that I think about it, I've noticed moisture sometimes coming from my air compressor.

It is the reason you have a drain on the bottom of your aircompressor tank. Every so often you need to open it so the water can drain out.

You must have seen the tank trucks on the road with the sign "Liquid Nitrogen" on them. They are pressurized. Should the tank leak, you would see a fog around it as it goes to gaseous state.

I have a large tank out back for our laser.

And THAT is why I clean my computer by removing the cover and using an electric leaf blower.
