Here's an International website for just about any chemical that is on the market today,,, So if your not sure of the Fuel additive Safety that your adding to your Fuel,,, Try looking it up here.

If its not there, then try the companies website that made the chemical for a Material Safety Data Sheet (MSDS)

While it's all well and good to read the MSDS for the stuff we use (or want to try) I think a little care is needed when assessing the actual dangers.

Two examples.
http://www.jtbaker.com/msds/englishhtml/p4830.htm
Now this is for drinking quality water. Under Hazards Identification it has a danger warning! But if you look closer it relates ONLY to a tiny impurity of nitric acid.

The next example comes from a thread in SSW where it seems that Thunderbolt glow plugs have a warning on the packet that they contain a chemical known to cause cancer. Now this may be just to warn Californians not to breathe or eat glow plugs but for interest's sake I looked up the MSDS for platinum wire at http://hazard.com/msds/f/cbn/cbnwh.html
One of the things it warns against is that inhalation may be harmful! Well duhhhhh....when was the last time you heard of someone snorting a roll of wire??

OK, so I'm being a bit fascetious here...but the point is that with moderate care even something as dangerous as nitro (look it up) can be used quite safely. There are other ingredients that used to be used that are avoided like the plague nowadays.

Downunder,

I understand your jest with this topic, but there are many that try components that they do not realize are VERY harmful to thier health just assuming that because a product can be purchased somewhere it must be safe. A very good example is the posts I have been reading about people using Mobil Jet II turbine oil in model fuel. This is a health hazard and should NOT be done. Turbine oil is a purpose made product and missusing it in this way is NOT smart.

Amen Jerry,

I was just about to post a very similar comment.

Most people have very incomplete knowledge regarding the chemicals they want to try and make fuel with.

Not only Mobil Jet II, but all the turbine oils are dangerous. While I'm at it, proplyene oxide is exceptionally nasty stuff, I've seen it missused many times over the past 25 years of flying. I guess its a good thing we don't see nitrobenzene around anymore or amylnitrate, all nasty stuff.

Bill Vargas,
You have done us all a service here by posting a place for folks to check out MSDS's. Thanks you.

Dr. Nitro, your welcomed

Don't get me wrong, I think it's a great idea for people to be able to go check out any exotic chemicals they want to try in their fuels (and virtually everything has been tried at one time or other) but what I'm saying is that the data should be read carefully to see how dangerous it might be in our use.

Take Mobil Jet Oil 2 which seems to get picked on all the time. Here's a quote from the test that caused the most damage.
"Repeated oral administration of 2 g/kg of a generic jet engine oil containing 3% tricresyl phosphate (TCP) (once/day, 5 days/week for 10 weeks) to hens (60mg/kg/day TCP) inhibited brain neuropathy target esterase (NTE) by 70% and caused ataxia or paralysis in 22 of 30 hens in this treatment group."
Basically this means don't drink it. Other than that, where is this so-called danger??

Yes, I use Mobil sometimes and even George Aldrich said it was the best oil he'd ever come across. No, I don't breathe the exhaust if possible because it smells bad and it's got all this unburnt methanol vapour in it and that's the stuff that worries me.

Downunder,

My point is the one you have alluded to is that turbine oil is a purpose made lubricant that is used in jet aircraft turbines not mixed in fuels as lubricants. The exhaust gases and unburnt oil in atomized form when breathed is a different toxicological study all together. The lungs can metabolize ANYTHING breathed in far more effectively than though digestion. Case in point breathing treatments are used in some cases to better and more quickly absorb medicines. Smoking, huffing, and doing drugs and the such are more effective because of the imediate contact with the basil blood vessels and the quick absorption through the lungs. Jet oil was never tested for these applications because it was never meant to be used in this application. This is the type of post I would say .... you have been warned proceed at your own risk. The same is true for Proplyene Oxide except this one is no brainer. Proplyene Oxide is extremely dangerous and shoul NEVER be used in model airplane fuels. It is a skin absorbptive carcinagen and is NEVER flushed from the body...it is cumulative in effect. What this means is everytime you touch it you build a constant an increasing level in the body. Once your bodies tollerance level has been reached things start crashing...ie organs. The exposure level is low so this may take years.....once again...let the user be warned. There is still...believe it or not.... at least to my knowleged, one fuel company still putting propylene oxide in theri fuels...if you are curious simply ask your fuel manufacturer "they are required to tell you".

If you smelled it you breathed it. Methanol is poisonous but the exhaust is not methanol for it burns. The smell is an additive to methanol give it odor because it is odorless. Jet turbine oil is meant to stay in the engine, not a pass through oil. It does not burn therefore if you breath it you are ingesting it. Yeah maybe it won't kill you today but maybe it gives you cancer later in life.

BTW. George Aldrich died of cancer. Maybe it was the jet oil or the chrome sleeves, or he just had a defective immune system. I don't know but I wouldn't want to take the chances he took. Much of this information wasn't available when he was young. If I were you I would use this information and maybe you will live longer than George did.

Combustion is never complete especially on two strokes without a pipe.

Well maybe so, but hardly any of it is methanol. Incomplet burning means that you have partialy burned compounds such as carbon monoxide. Which will kill you quicker than methanol.

Turbine oil is a very high temperature oil. it usally has a indictor color of yellow so they know when its there. The people in the jet engine maintance business use protective clothing when using the stuff. It is loaded with heavy metal addative to inhibite burning an it is these materials in the exhaust that are dangerous. No they don't kill you right away they acumulate in the body and get you later.
