Water water Everywhere, but not a drop to drink.  And Air about 19.5% O2 and the rest N2 and trace gases.   Sea water.Try it at 4 ATA.  And someone want to tell me how much it costs to install a water shower. Looked it up; usually several hundred to serveral thousand dollars.

And AIR at1 ATA.  You need a bloody SDS to tell you about there things?  Where did I leave my hat?

Maybe I should go back to teaching at a School of Public Health.

Hey, now that you mention it, they still haven't sent us an SDS for the water they are supplying.

I think Edward Movitz has answered the conundrum:  it boils down (sorry, couldn't resist) to the origin.  If water is purchased from a chemical supply company,  the company must provide an SDS according to GHS.  If water is piped in through the plumbing,  there are regulations for what comes out of the spigot.    I keep a copy of an SDS of H2O as liquid water on hand for my schools.

However,  recognizing that my world is the K-12 science classes, the two main hazards posed by water (absent other chemicals) are 1) dangers of boiling water and 2) the slippery and almost invisible nature of water spilled on a linoleum floor.  Neither of these appears on the SDS but both have resulted in student (and teacher) injuries.

One more water joke:

Johnny was a chemist's son
But now he is no more.
For what he thought was H2O
Was H2SO4.

Cheers everybody

You might want to check out the website www.dhmo.org<http://www.dhmo.org>, which has an MSDS for dihydrogen monoxide (DHMO).

My curiosity will not allow me to wait until April first, when it might be more excusable, to ask this question.

There is a chemical which can be found in almost every laboratory.  Most laboratories even have it piped in.  There are (M)SDSs for this material and yet, while I am told that we are required to have the (M)SDS for each of the chemicals in our laboratory on hand,  I don't believe that many laboratories keep a copy of the (M)SDS for this substance in print.  I refer, of course, to water.

OK, I hear you saying "Of course no one has the (M)SDS for water on hand.  It's water."  And I agree: I mean it's in the safety showers, we wash our hands with it before leaving the lab.  But it's a chemical.  I can understand why I would make an exception for it, but does OSHA?

Can anyone tell me why safety documentation is not required for water?  Or is it?  Or is it, but no one makes a fuss about it?

Thank you very much,

Ben
