SUMMARY

Accidentally swallowing a tiny amount of 70% ethanol poses minimal health risks, primarily depending on the definition of 'tiny.' Lab-grade ethanol is often denatured, making it unsafe for consumption. While consuming close to half a liter of pure ethanol can be dangerous, substantial amounts (approximately a quarter of a cup) of denatured ethanol mixed with methanol can lead to serious harm. The discussion emphasizes the importance of understanding the specific grade and composition of ethanol used in laboratory settings.

PREREQUISITES
  • Understanding of ethanol and its various grades, including denatured and analytical grade.
  • Knowledge of the health effects of alcohol consumption, particularly ethanol and methanol.
  • Familiarity with laboratory safety protocols regarding chemical handling.
  • Basic awareness of alcohol toxicity and its implications for human health.
NEXT STEPS
  • Research the differences between denatured and analytical grade ethanol.
  • Learn about the health risks associated with methanol exposure.
  • Investigate laboratory safety measures for handling chemicals like ethanol.
  • Explore the effects of high-proof alcohol consumption on human physiology.
USEFUL FOR

This discussion is beneficial for laboratory technicians, chemists, health professionals, and anyone involved in chemical safety or alcohol consumption research.

If you accidentally swallow a tiny amount of 70% ethanol in a lab, would you put yourself at a health risk?

Not likely. You need to define 'tiny', however. Lab grade ethanol has been denatured. Not so good to drink. Make you sick. One professor at college used to denature his ethanol with phenolthalein. Baaad ju ju! ...and bad doo doo too.
 


I was spraying a bottle, and more accurately a minuscule amount got in my mouth.
 


People have been drinking it for five millennia. You need to drink close to half a liter of pure ethanol at once to put yourself in danger.

As chemisttree pointed out though, no one knows what other nasty chemicals might be mixed in with the ethanol. Methanol is often present and it's considerably more dangerous. But still you'd probably have to drink substantial amounts (quarter of a cup?) to cause permanent harm.

Half a litre!?

That would be like drinking a about litre of something like vodka at once, and I think that would be more than enough to make you quite out of it :)

Anyway... analytical grade ethanol isn't denatured... is it?
It depends exactly what grade of EtOH you're using in the lab, and if it is denatured.

In Russia it is considered normal for an adult to be able to drink a bottle (0.5 l) of vodka at once without experiencing any outward ill effects. For mass celebrations such as weddings, organizers would typically provide one 0.5 l bottle of vodka and at least one 0.75 l bottle of wine per attendee.

Two bottles at once will probably knock you out, you'll sleep for 12 hours and wake up severely dehydrated and with a bad headache, but without permanent damage.

It's quite hard to drink yourself to death, because, unless you push yourself to drink really fast, you'll pass out before you had a chance to drink the lethal dose.
 


Some is denatured and some is not . And sometimes they denature it with methanol .
They sell everclear in the liquor store which is 95% ethanol .
Since you said it was 70% what is the other 30% .

Is it for this reason that marriages don't last long in Russia? :smile:
 


The other 30% would be distilled water. Its been 2 weeks, and I feel fine. It was a very small amount. The alcohol was sprayed from a bottle, and some got in my mouth.
