For a bit of fun, here are some excerpts from a Manufacturer's Data Sheet. Can anyone guess the chemical?
SECTION 4: First aid measures
8.2 Exposure controls

Does it begin with M?

Those are all generic warnings so could be almost anything. I was going to guess sodium chloride as well but I will say sodium bicarbonate.

Could be anything. I've noticed that a lot of Safety Data Sheets tend to err to the "safe" side with all sorts of over the top precautions. Not really helpful. Amongst other thingss if you put lots of nonsense on a well esablished materail it "dilutes" th importance of the precautions and can cause them to be ignored on worse materials.

Hi, it seems to reflect some white powder that was used by the company I used to work for many years ago. The powder was called Hydros, which I guess is a hydrogen compound. I never did know what it's exact definition was, but it was mixed with water and went into the process after being through an acid scrubbing process. Horrible smelling stuff and would take your breath away and would burn off rust, but any iron alloy that it came into contact with, would rust as soon as you let it dry. One danger side of it was, it was spontaneously combustible if it got damp, and that did happen once with a major fire ensuing as result with the fire brigade and chemical unit attending.

Not quite, for example the Firefighting measures include: 'Suitable extinguishing media. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.' So it burns, and can be put out by water. That eliminates all non-combustibles like Common Salt, but also Fats and Oils. The warning about alcohol resistant foam indicates this is an alcohol or something like an alcohol, perhaps a ketone.
Whatever it is it's relatively harmless. It's not Chlorine Trifluoride!

Sorry Dave see MSDS for salt from Fischer scientific similar firefighting (just plain foam though). I've never seen salt burn!

Distilled (or deionised) water.

Glad I'm not a fire-fighter. Spraying water on molten Sodium Chloride generates Hydrogen Chloride and the reaction is violent. I believe a cupful of molten salt tipped into a bucket of water goes bang.
Similarly spraying a lot of water onto red-hot coke normally puts the fire out. Obviously water is safe. Or is it? Not if the amount of water is kept low relative to the amount of coke. In suitable proportions and when hot enough, Carbon reacts with the water and converts it into a mixture of Hydrogen and Carbon Monoxide. Which can go bang, and is toxic!
Don't think either disaster is likely to happen in my workshop! I reckon MSDS appear over-cautious in the face of common sense because they're covering what might happen in an industrial context. World of difference between salt on the dining table and several tons caught in a fierce fire, fire-brigade on the way.

MSDS sheets are designed to scare people to death! And as others have said, this one could be anything, so I'll guess at weak Acetic Acid, it's what I pour over my chips. I prefer to call it by its proper name - Vinegar!
Sillyolddufferr mentions Sodium, I was an apprentice on the Sodium plant, if you melt salt (Sodium Chloride) you split it into its metallic compound Sodium and Chlorine gas (that's the Chloride). It was an interesting if scary place to work, watching the process guys on top of the cells puddling the molten sodium by hand! then It was cast into large ingots or transferred into a special heated road barrel. The plant was decommissioned in the 90's.
You put out a Sodium fire with salt, lots of salt!

+1 for water - it's got to be nuts of Neil wouldn't have posted. Had a look at the MSDS for Cleanline deionised water:
Ingestion: Rinse mouth thoroughly with water. Give plenty of water to drink. Get medical attention if any discomfort continues.

No idea what it could be but... I know what it is not and that is... Chlorine Triflouride
