Dear Birck Users, As part of the Birck Modernization Project the contractors need to begin working in N-Bay starting on Monday, Aug. 4 and continuing through that week, finishing their work late Friday, Aug. 8. The entire bay will be shut down during this week-long period, and there will be no access to these tools during this time: * Nanoimprint * Hot Plates * MJB3_2, MJB4, MA6, SB6, Heidelberg * Spinner 1, Spinner 3 * Optical Microscopes * Apreo SEM. Please plan your research according to this schedule and this tool availability. Thanks, Ron

Solvent Waste
by Ronald K Reger 21 Jul '25

21 Jul '25

Dear Birck Users, Earlier today an engineering staff member observed a graduate student rinsing a beaker with the isopropanol squirt bottle directly into the drain in a photoresist hood, putting organic solvent directly into the wastewater system. We critically remind users that NO organic solvents are permitted down the drain whatsoever, no exceptions. This user was under the impression IPA was acceptable, and this is not the case. Organic solvents are to be poured into the appropriate non-halogenated or halogenated solvent waste bottle, and the bottle is to be labeled with the volume of the material added to it. NONE of this organic material is to be poured down the drain, regardless of where the drain is, as this will damage our Birck drain system. Please adhere to these standard Birck solvent waste practices completely and immediately. Ron Reger Birck Engineering

Solvents in Acid Hoods
by Ronald K Reger 21 Jul '25

21 Jul '25

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

No UPW shutdown today. We have modified the work schedule in an attempt to reduce the total number of shutdowns. The next UPW shutdown will most likely be several weeks away.
