canned air, a warning

[Motherland]

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

Yup, probably condensed water vapor more than anything else.
Water's a really cool substance, the difference in electronegativity between oxygen and hydrogen produces some weird physical results.



You'll notice that the solid-liquid barrier points the left (unlike the right like CO2 and most other substances). This is because ice is less dense than water due to the polarity of the molecule, which is... I don't know, it's special. The vast majority of other substances have solid states that are denser than their liquid states.

Also my can of air says that it contains difluoroethane so there's probably some pretty nasty fluorine compounds (hydrofluoric acid? did it sting?) coming out of that combustion.

Didn't sting so much as irritate the crap out of my throat and lungs...it was definitely not fun...and the pungent odor made me get the heck out in a hurry!  Even held breath when I went back in to open the windows..still feel sore throat... and yea, it has diflourethane in it...

I'm a derp and didn't do all my research, disregard.

I personally posted it several places today, including here, rcgroups.com, ohioriders.net and assfaultjunkies.com, as wee as Facebook.  The portion that burned was difluorethane, per the can stating that was among its contents.  I assure you this DID happen today, as unlikely as it may be.

Hmm, saw it from one of my friends on Facebook, and he's a pilot. By any chance, care to say where you're from?

Milford, Ohio.

Definitely not him then, lol. Do you know a guy named James Hewlett?

[Sol75]

Can't say that I do...  I have some ah guys on Facebook but dunno if you are one of them...my profile puc is me standing by a piper Cherokee 180, if that helps any?

p.s. chemistry is the best science

I beg to differ.

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 hopefully, you've got water separators in the lines.

Years ago on my 1980 Rabbit I had a slow leak in one tire. I just kept putting air into it for about 6 months thru the summer. Then one cold day in December the damn thing was vibrating so bad I could not drive it.All the water vapor from the repeated air re-fills had frozen. I was forced to pull that tire off the wheel, must have had a quart of frozen water in that tire.

Modern cars with pressure sensors need really dry air to protect those sensors from corrosion. I have heard of guys who are now filling their tires with nitrogen to avoid water problems from gas station air pumps.

   i almost blew my gas stove up using some of that canned air to blow debris from the burner, i didn't turn off the pilot lights...after i cleaned up the mess, i looked at the label and the propellant was some sort of flammable "something something...ane". 

that's when i got lot more picky. tried this and it was worth the cost...

Water separator in LN2 lines?

Just admit it you were HUFFING it! http://en.wikipedia.org/wiki/1,1-Difluoroethane

   Unplug those electrical devices when cleaning.  

  Since we are into diagrams here is a proper cleaning technique.
