To All Good morning! We have found a lot of the dirty glassware, waste bottles, and chemicals while cleaning the Lab#333 hood. We are not sure if these are dangerous chemicals, waste materials, or samples. We have asked multiple LORRE members, but nobody can account for what was found. This makes it difficult to fill out a pickup form.Purdue REM will be spent a lot of money to detect unknown liquid chemical in each bottle. As a friendly reminder: 1)The Hood is not a storage space, please put chemicals away properly after using them, and arrange for the disposal of waste. Keep the work space clean and clear while not experimenting. 2)Do not use the hood as a way to dispose of chemicals. Do not allow for volatile compounds to dry in the hood, this is dangerous to the health of all people who use the lab space. Openly exposed chemicals, especially volatile ones, have the potential to pollute air and expose individuals outside and inside the building. This practice should not be used. Instead they should be capped and stored for REM pickup. 3)Liquid biological waste should be collected in containers for autoclaving or chemical disinfection before disposal. Thank you to *Evan E Scwinski, Raymond Red Corn, Dan Hoban, Justin Couetil,* and *Nwadilora* *Amarachi Ezenwukwa* for keeping the lab space safe and encouraging chemical safety throughout LORRE. Thank you, LORRE safety committee.
