Dear Birck Users, Over the weekend a user reported that there were solvent bottles used in an acid hood in H-Bay. This is a dangerous breach of Birck fume hood protocol! We have segregated acid/base use from solvent use for the critical reason that some solvents when mixed with acids can cause explosions and/ore fires. This practice must stop immediately for the safety of all users within Birck, and for the protection of our assets in the facility. We know that the temporary lack of fume hoods is causing cramped working conditions but the segregation of acids & solvents must be strictly adhered to! Please note this urgent request and do not cross solvents into acid hoods and vice versa. We're working with the construction company and architects to remedy our fume hood shortage, but please keep safety as our top priority. Thank you for your support. Birck Management
