I think a child taking a large gulp would be EXTREMELY dangerous though. Same for pets and wild animals.
Folks back home in Texas use Anti-freeze to kill coyotes all the time. Just saying.

Also, when I was a kid, we had this cat, and she got into some anti-freeze somewhere. Ended up with severe neurological damage. It didn't end up killing her, but she always walked sideways after that.

You can skip the speculation and just Google the MSDS and look for the LD50 value. Thanks in part to the Right to Know act, millions of animals have make the ultimate sacrifice to help you make more educated decisions, and what quantity/weight will kill half of the sampled population. This from Prestone...

Quote:
ACUTE TOXICITY VALUES:
Ethylene Glycol:
LD50 Oral Rat: 4700 mg/kg
LD50 Skin Rabbit: 9530 mg/kg

Diethylene Glycol:
LD50 Oral Rat: 12,565 mg/kg
LD50 Skin Rabbit: 11,890 mg/kg
So with the presumption that your body is like a rat, and you weigh about 80kg (176.37 pounds) you'd need to ingest 4700*80= 376,000mg, or 13.26oz., to die about half the time.

For a 9kg kid of pet (20 pounds), the math works out to just under 1.5oz. Yes pretty serious..

OK, this is actually what I do for a living, so here's more than you wanted to know about antifreeze...

The problem with antifreeze is that it contains ethylene glycol (EG). Diethylene Glycol is found in some brake fluids and some manufactures put a little bit of it in their antifreeze. Methanol is found in windshield wiper fluids amongst other things. Some antifreezes do contain methanol but it's not very common. The concentration of EG in antifreeze is usually about 95%. For the sake of this conversation, we will assume antifreeze that is 95% EG and ignore the other components for the sake of simplicity.

The metabolites of EG cause kidney failure and metabolic acidosis (lowering your blood's pH). Either will kill you eventually without treatment, but the metabolic acidosis will kill you a lot more quickly, so that is usually the cause of death. If you survive the metabolic acidosis, you may live to experience the joys of needing dialysis 3 days a week for the rest of your life.

Now, as for an amount that will cause problems up to and including death. We usually worry about a blood concentration of > 25 mg/dl. Some examples:

For 95% EG in a 70 kg (154 lbs) person, that would be about 14 ml, or half an ounce. So, is tasting a drop off your finger going to be an issue? No. Is taking a swig from the gatorade bottle your redneck brother-in-law uses to store his antifreeze going to be an issue? Probably.

For 95% EG in a 10 kg (22 lbs) toddler or small dog, that would be about 2 ml (less than half a teaspoon). So, if a toddler licks it off his finger it's probably not going to be an issue, but if they drink it from a container or even slurp it off a garage floor, it's gonna be a big problem.

The good news: with prompt treatment (getting to an ER within about 6 hours of ingestion is usually sufficient) EG poisoning is rarely fatal. There are actually 2 antidotes available (good old ethanol being one) and with appropriate treatment, people are usually discharged in a few days with no permanent complications.

Important advice: Don't try to figure this stuff out on your own. If you have reason to believe you or anyone you know has ingested more than a taste of antifreeze, call your local poison center at 1-800-222-1222. If you think a pet is at risk, call the national animal poison center at 1-888-426-4435

Sorry for the thread drift...

Very interesting, thanks! I've got some used anti-freeze on the garage floor in a milk jug, this motivated me to get rid of that.

Oddly enough, there is no warning label on the side of my .45 or 9 mil.
I'm surprised it isn't on the grips or permanently painted on the side of the barrel in white.
I fully expected, "While this device contains lead, it is not a pencil. Do not attempt to write your name with this device."

too bad the critters can't read warning labels.

great contributions! None of them really work for the project I have, but great read!

Me too. Parts store won't take it with the oil they recycle.

Where do you take yours?
