That MSDS consists almost entirely of “not applicable”.
Yes, I know. It’s a joke, son.
never mind.
That’s an interesting MSDS. Under “precautionary measures to minimize risks and potential hazards,” the include the following:
2.4.5 Keep away from heat/hot surfaces/sparks/open flames. No Smoking.
2.4.6 Use explosion-proof electrical/lighting/ventilation equipment.
2.4.7 Use only in well-ventilated areas.
Do you think maybe any of the other stuff on there is overkill too?
It says “may” be harmful if swallowed, and it lists the health hazard level as 1, the lowest nonzero level of hazard. Doesn’t seem like much to worry about here.
It also lists Extinguishing Media(!): Water spray, dry chemical powder, or appropriate foam. You know, in case you didn’t follow those precautions, and your ultra-pure water caught fire, and needs to be extinguished with water. Presumably less pure.
I think @Jackmannii is right, and @Fozzie_Dabear was just making a joke.
But the MSDS itself is kind of funny. Like,
9.8 Vapor Pressure: Not Available.
9.9 Vapor Density: Not Available.
9.10 Specific Gravity: Not Available.
9.11 Evaporation Rate: Not Available.
9.12 Solubility in Water: Not Available.
How is that information not available for water?!
9.1 Appearance: Clear Solution.
Solution? Dissolved in what?
No it’s a rock group. Or ought to be.
Six comments:
(1) Why do some skating facilities insist on using reverse osmosis, distilled, and/or deionized water for the ice? Because otherwise the ice might be cloudy and obscure an advertisement or logo on the surface underneath the ice for which some sponsor has paid a whole bunch of money just so people will look at it.
(2) The reverse osmosis process often wastes a lot of water. Typically, two units of water are wasted for each unit of reverse osmosis water that is produced.
(3) Some water purification systems claim to use reverse osmosis but really it is just ultrafiltration. But the marketing people think that “reverse osmosis” sounds much cooler than “filtration”.
(4) Very pure water might not be safe to drink because the purification process also removers disinfectant(s) that were previously deliberately introduced into the water to deactivate pathogens. When all the COVID hysteria was at its height, I labeled some water systems “not intended for human consumption” for this reason. I knew everyone was going to drink it anyway when I wasn’t looking so I didn’t bother labeling it “human consumption prohibited.” At least I could say I did something to try to stop the spread of the COVID virus. In reality, very little, if any, COVID transmission is caused by drinking contaminated water.
(5) The claim that very pure water will “burn your insides” is complete and utter nonsense.
(6) At least in the United States, no one has to worry that a steady intake of very pure water will eventually result in depletion of electrolytes in one’s body. One can of Campbell’s Chicken Noodle Soup (or just about anything else Americans eat) will supply enough electrolytes to get you by for a really long time.
My grandfather managed an ice house in the great depression. He got angry when they made cloudy ice. But the cause then was due to the ice freezing too fast and trapping air bubbles in the ice. That wasn’t just a cosmetic defect for him, he knew that cloudy ice would melt more quickly and be of less use to his customers. I’m not sure if he knew the air bubbles were the cause, but he knew the effect. If it was frozen slowly, it was apparently clear because air had time to escape, using the same water source.
I think they opened for Blue Oyster Cult at Las Vegas in the late 90s
Somebody pointed this out earlier, but here are the first aid remedies associated with pure water:
Section 4 - First Aid Measures
4.1 Eyes: In case of contact with eyes, flush thoroughly with water. Contact
physician.
4.2 Skin: In case of contact with skin, wash the affected area with copious
amounts of water. Contact a physician.
4.3 Ingestion: If swallowed, wash out mouth with water provided person is conscious.
Contact physician.
4.4 Inhalation: If inhaled, remove person to fresh air. If breathing becomes difficult,
contact a physician.
4.5 Puncture Wounds: Wash thoroughly with water. Allow to bleed freely. Contact physician.
It says nothing about what you should do if you have already exploded. I feel this is an oversight.
Call coroner.
ETA. Use water to clean up
They don’t even know how to protect us from it!
8.2 Personal Protective Equipment:
8.2.1 Respiratory Protection: This is a laboratory-use product for which no industrial protective
equipment has been designated.
Most water safety datasheets are normal. This one, though:
You’re a goner.
People say it because it’s true…?
If you actually managed to keep a tank with 100% distilled water with nothing dissolved in it, that would absolutely kill most if not all fish kept in it due to electrolyte loss or gill and/or kidney damage. They’re not going to pop like a balloon or anything dramatic, but neither would they be able to acclimatise. Fish have an osmoregulation system that allows them to adapt to a range of osmotic pressures, but that’s only going to work within limits. Limits vary between species, but actual distilled water would be outside the long-term survivable range for certainly all commonly kept species and probably all fish.
Of course, impurities are going to build up fast in any normal tank, and it’s completely fine to use distilled/RO for partial water changes, but if you did place a fish into actual pure distilled water, it wouldn’t last long, even if you did it gradually, and even dissolved solid levels that are too low can cause damage to species from hard-water areas, because their osmoregulation systems are stretched to the limit.
Osmoregulation is complicated… (hopefully that paper’s actually open access and I’m not just logged in, it’s hard to tell).
I don’t know much about scientific values but ‘’ as our oldie says drink water direct from rivers or wells, filtering them is not good as for concerned about health
They’d last a few minutes and then die, probably longer if you gave them some way to breathe.
This reminds me of Randall Munroe asking his friend (who worked at a nuclear power plant) what would happen if he tried to go swimming in the pools where they stored spent nuclear fuel. His friend thought for a bit and then said “you’d die from the gunshot wounds.”
