"You can request the "Hazardous Material Data Sheet" from the manufacturer."
I think every online listing should be required to have a link to the Hazardous Material Data Sheet. Otherwise, it is too time-consuming to learn about the hazard.

Do you think vendors should put a link to this on every bottle of water?

most are at least accepted as food addictives

Which would be relevant if you were consuming them in food. You aren't, you're using them in a form (heated vapors) that isn't generally accepted as being safe. You're also handling them at concentration far, far above those found in products on the grocery shelf.
 
In fact, the MSDS forms for propylene glycol and glycerin make for some very interesting reading.
  Both recommend avoiding inhaling the vapors.
 

as long as my sources do not lie about the base components (VG and PG) I should be way safer

Have your sources provided you with actual data, or do they merely repeat the mantra "it's food grade, so it must be safe"?
 

There are no such things as "addictives", unless they mean aroma. And again, those, if coming from a reliable, trusted source, should be safe.

Why should they be safe coming from a "reliable, trusted" source? Have you seen their data, or are you (again) merely repeating the essentially religious (that is groundless and taken on faith) propaganda of the vaping community?

Weird that the MSDS for prussian blue is still pretty scary.

Alright - we'll stick with the titanium dioxide, then, which despite getting sprayed all over people's bodies in summer is still a known carcinogen. Oddly enough, it rates lower on the MSDS health risk scale than prussian blue.

Water is wet.

It is also comprised of two Hydrogen atoms and one Oxygen atom.

It also has a Ph of 7 and is considered a Universal Solvent.

It Also has a MSDS for it. That's right. There is a Safety Data sheet on WATER because the government felt a need to inform people that you can't breath in it.

In other news: 3D TV, a commercial gimmick for people to buy expensive shit, has finally kicked the bucket. Reports are also coming in that the Virtual Reality fad is also following suit. VR, as you know, has been a fad that both the Game Console and Electronics companies have been trying to shove up people's ass like 3D TV, but has failed every time.

Captain Obvious reporting.

Because some people got scammed by /pol into believing that hookers were paid to pee on Obama's bed in Moscow. Which of course the media decides to devote 24-7 coverage to. They've investigated it for months and have yet to produce any corroborating evidence worth a damn, and instead have only managed to inform us of the obvious, that Russia runs RT, America runs PBS and the Brits run the BBC. That said, I will give them credit for nothing that, "Disclosures through WikiLeaks did not contain any evident forgeries" (p. 13).

Meanwhile, good luck finding stories about the DisruptJ20 people who were caught plotting to gas people with butyric acid by pumping it into ventilation shafts. Be sure to read the MSDS on what that stuff is.

It would be interesting if a company named "XB" chemical company was marketing monopersulfate , which is also known as "oxone". "XB oxone" would be a perfectly logical name to call it.

I think in that case, it would be an interesting case to watch Microsoft try to claim domain rights... but from what I see, this is a pure case of domain squatting... just another business model much like tying up real property in order to collect rents, as well as diverting your income stream to something taxed more favorably than earning it. For some reason, our Congress really has something about punishing people's earnings with tax law. Its my belief they are just trying to force everyone onto the government dole.

I think it's fair to assume that a substance is toxic well below the lethal dose.

The substance is toxic, period, regardless of dose. In fact, virtually anything, when given in high enough quantities, can be dangerous to humans. As most of us know, it's perfectly possible to die from water poisoning.

So, yes, caffeine is toxic to people even in lower dosages. It's also potentially dangerous to people in lower dosages, but as a measure of toxicity, we can take the LD50 as an indication that, in this case, most people would need to consume far more than they could ever reasonably be expected to consume in order to be in danger. And if you check the MSDS for caffeine, you'll see that it's labeled as being hazardous with a health hazard rating of 2, but that's pretty mild in general, and it's referring to it in an undiluted pure form too.

The mercury in thimerosal is not non-reactive, you blithering ignorant idiot. Stop it with the sodium chloride bullshit. Start here. "Thiomersal [alternate spelling] is very toxic by inhalation, ingestion, and in contact with skin (EC hazard symbol T+), with a danger of cumulative effects ... Cases have been reported of severe poisoning by accidental exposure or attempted suicide, with some fatalities ... Animal experiments suggest that thiomersal rapidly dissociates to release ethylmercury after injection; that the disposition patterns of mercury are similar to those after exposure to equivalent doses of ethylmercury chloride; and that the central nervous system and the kidneys are targets, with lack of motor coordination being a common sign."

Check out the MSDS here or here. "Highly Toxic (USA) Very Toxic (EU) ... Very toxic by inhalation, in contact with skin and if swallowed. Danger of cumulative effects ... Calif. Prop. 65 reproductive hazard. Target organ(s): Nerves. Kidneys."

Had you asserted that the exposure to an undoubted toxin via vaccination is so low as to make the risk slight, I would have treated your anonymous cowardly post as rational. As you didn't do that, but instead brought up completely erroneous parallels, and you are not seriously considering pros and cons, you make a pretty good punching bag.

My original post, moderated to virtual invisibility by idiots, still stands:

Since pretty nearly everyone responding has agreed that flu shots are clearly void of any potential whatsoever for adverse health effects, I thought maybe it might make sense to find out what the CDC thinks about this subject [cdc.gov].

"Thimerosal is a mercury-based preservative ... Since seasonal influenza vaccine is produced in large quantities for annual immunization campaigns, some of the vaccine is produced in multi-dose vials, and contains thimerosal to safeguard against possible contamination of the vial once it is opened ... Since 2001, no new vaccine licensed by FDA for use in children has contained thimerosal as a preservative."

So, can we dispense with the idea that ALL objection to vaccination is based on luddism / unreasoning superstition? Hey, it's only a suggestion, but it seems to me that a reasoned evaluation of the pros and possible cons of shooting substances containing mercury compounds into the bloodstream is not out of bounds. For me, I am inclined to the conclusion that the effectiveness of flu vaccines at the present state of the art are in NORMAL CIRCUMSTANCES not worth a crap to the host individual, but that they may be worthwhile from a herd immunity perspective. This particular case is very much complicated by the fact that the personnel are working in close proximity to vulnerable patients whom they are sworn to protect. I think the employer in this particular case is in the right, although the science is not as clear-cut as I would like.

Finally, the CDC goes on to say "Data from several studies show the low doses of thimerosal in vaccines do not cause harm, and are only associated with minor local injection site reactions like redness and swelling at the injection site." Sounds to me like they are talking out of both sides of their mouth. They don't recommend the use of any thimerosal-bearing vaccines in children, yet they tell us thimerosal is "safe", as if safety is an all-or-nothing, either-or condition. But we know that harmful effects of mercury on the body are cumulative and are not entirely limited to children.

Read the book but here is some info;
Most waxes are bees wax, carnauba and candelilla wax, shellac or oxidized polyethylene. So the waxes use are harmless.

'No scientific evidence that it's harmful' is overbroad. In the tiny amounts present in vaccines, it may be OK. The MSDS is still pretty scary, though! See: http://www.sciencelab.com/msds.php?msdsId=9925236 . Mutagenic, repeated exposure may cause organ damage, etc. Organomercury compounds are no fun, really.

... (though not because there is any scientific evidence that it is harmful)....

I have to call you on that. There is a lot of data on thimerosal toxicity and most of it is summarized in the MSDS data sheet (PDF). Pay particular attention to chronic exposure like the one you get every year from your flu shot. Kidney, liver and CNS damage don't strike me as particularly harmless.

Besides there is no excuse why it is still in use as vaccine preservative. There are alternative preservatives, and in many cases preservative use is not even needed. Producing the vaccine in a clean facility and/or sterilizing it by filtration or gamma-irradiation (where appropriate) should do the job quite nicely.

The LD50 of capsaicin is estimated to around 47mg/kg (mice), so it's only a case of "the dose makes the poison", but an actual toxic substance (and officially classified as such).
Some murders by capsaicin poisoning have even been reported.

But seriously anything with an MSDS sheet that contains an LD50 should never be eaten.

Seriously? How do you live without ingesting water (LD50 90 mL/kg):

Or table salt? (LD50 3000 mg/kg)

What about sugar? (LD50 29700 mg/kg)

Or caffeine? (LD50 192 mg/kg)

http://www.sciencelab.com/msds.php?msdsId=9927475

Enough of just about ANYTHING can cause serious problems if ingested. The presence of an LD50 on an MSDS sheet means nothing if you don't bother to understand exactly what it means in the real world.

It's exactly like that. Pocketknives are just as dangerous as the blades they contain. If you remove the blade from the pocketknife, it becomes much more safe.

Using salt as an example is asinine. Salt is safe, while the elemental components of salt are not.

I didn't post an MSDS for Mercury as an element, I posted one for Thimerosal - the compound. If it's so safe, why is it classified as "Highly Toxic"?

The MSDS for chlorine and sodium as elements is radically different from the MSDS for sodium chloride as a compound.

The MSDS for Mercury vs Thimerosal are not that different.

Yes, the United States.

The fact that you (and many others) believe otherwise is EXACTLY why it's dangerous to do that.

Here's a material safety data sheet for hydrazine: http://www.sciencelab.com/xMSDS-Hydrazine-9924279 (pdf). It is extremely nasty stuff. Note in particular the full-suit requirements, and the teensy-sized lethal exposure levels.

Hydrazine is one of those substances where if you can smell it, you're already dead.

So maybe this is just a little drama. Maybe there was a secret self-destruct device in the (totally secret) satellite, and they pushed the button just as the missile approached, thus guaranteeing a success.

But do NOT disrespect the hydrazine.

Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation...Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water.

So they won't be fogging airports with this stuff anytime soon.

In addition, as both an amine and an aldehyde, I'm willing to bet this stuff has a very strong odor.

While lead sulfide[PDF] isn't particularly hazardous, I wouldn't categorize it as safe. Lead poisoning is on my list of things to avoid. YMMV.

Don't forget the SRBs, they provide the majority of the power produced at liftoff.

From ScienceLab http://www.sciencelab.com/page/S/PVAR/10408/SLA272 5 it'd run about $30 million... I wonder if NASA gets a volume discount?

Fluorinert FC-77

100 ml - $257.38
250 ml - $561.74

There have been cooling systems on /. that cost at least as much as 2 liters of this. I wouldn't be surprised if someone was already doing it.

Oh, here is some nifty stuff from 3M:
Fluorinert.

3M(TM) Fluorinert(TM) Electronic Liquid FC-77

Heat Transfer Fluids
The wide liquid range of Fluorinert liquid FC-77 (-110 deg C to 97 deg C) makes it ideal for use in automated test equipment (ATE) and other semiconductor process equipment. Its high dielectric strength means it will not damage electronic equipment or semiconductor wafers, chips or packages in the event of a leak or other failure.

In addition, FC-77 liquid is chemically stable, nonflammable and practically non-toxic.

At over $500US for 250mL, it would take a princely sum to fill a fishtank....

oops. linky

Yeah. There are thousands of things that are totally legal to purchase that can be used to make all kinds of goodies. Check this place out . I used to get all of my stuff from them before I got busted by the polese. One of my friends made the bomb, he said he was just messing around with acetone peroxide when he made it. I think AP was what the shoe bomber guy used. They say that it's really unstable, but it's not. It's cool, it makes a huge fireball w/ very little noise. Ketone Peroxide was what got us into trouble though. I can't tell you how to make that, because I don't want to get into trouble again, but it is a hugeass powerful explosive :) Annnyway, it's ridiculous to outlaw rocketry when such stuff can be made by two 16 year old kids out of household chemicals.
