Hi!

I accidently stored some ml of chloroform in a 50 ml falcon tube outside of the fume hood for some time (we of course nrmally keep these tubes within the hood). I was shocked when i looked at the tube this morning and saw it was
empty, ie the solvent had diffused out.

I have learnt never to make this mistake again, but could this have long term conequences for me and my collegues, or is the risk low, so i can count this
as a learning experience?

No way. Assuming there is any kind of ventillation (there has to be!), the
rate of evaporation is bound to be low enough to not produce anything
near dangerous levels.

especially when that was a 1-time event, rather than a chronic exposure over years.
