You should never drink from lab glassware because it may contain residues of harmful chemicals or reagents used in experiments, even if it has been washed. Consuming these residues can be harmful to your health. Lab glassware is not designed for food or beverage consumption and can contaminate your drink.
Immediately get everyone out of the lab. Operate any air venting system in place to remove the vapours, or quickly open windows before leaving the lab.
