1. GUIDE TO OUR BUILDING (C1) - FUNCTIONALITY AND SAFETY Dr. Christian Stadler (stadler@chemie.uni-wuerzburg.de)

2. Getting in… Getting in (and getting out)

3. Online vs. offline

4. Getting in, without getting in trouble Always carry your transponder with you. Some doors will lock automatically behind you! Staircase doors will lock at 7 pm! Update your transponder every morning when you enter the building. It becomes inactive after less than two days of not updating it! Be aware of the different locking modes! They are explained in the information sheet you got when receiving your transponder. Contact Markus Braun (room 00.037) in case of having trouble with doors, and, particularly, in case of loss of your transponder.

5. Getting out! No transponder needed! Just follow the signs!

6. Where to meet

7. Fire! (Please take care…) Escape ways, fire extinguishers, phone numbers, etc. Fire alarm Emergency stop for flammable gases 112 (emergency call) and/or 84444 (service center)

8. Fire! Avoiding contamination… Close open doors in the corridors!

9. Fire! Stopping flammable gases… Usually located at the end of a corridor, close to the stairway. Affects the whole floor!

10. Fire! Just another emergency stop Emergency stop for electricity and for flammable gases. Watch the room number! (Some ‘rooms’ actually are corridors)

11. Fire! Only run or try to fight it? Use an appropriate fire extinguisher! But please don’t risk your life. Powder D CO 2 foam ABC

12. Other legal(!) things in the corridors… streetwear lab coat only bottles

13. What else is new? Lights are switched off automatically in the late evening (at 9 pm?). Automatic lighting in the stairways and the basement (and even some automatic doors for easier transportation). Several rooms‘ temperature is controlled electronically.

14. Do not… …store any flammable materials in the corridors (not even in the lockers)! …park bicycles inside the building! …block doors open! …use the elevator in case of fire! …use multi-outlet power strips without previous permission by Mr. Brunner!

15. Laboratories: everything‘s changed! Dynamic ventilation system according to daytime and usage of fume hoods (with variable air volume flow and supportive flow technology). Automatic sashes and horizontally moveable access openings. Safer vacuum installations. Nitrogen, compressed air and cooling water everywhere. Lots of safety cabinets for flammable liquids. Workplaces at the windows with decent lighting and pretty much space.

16. Fume hoods, from bottom to top Handles and switches for all outlets inside the fume hood Safety cabinets for flammable liquids (maximum size is 10 l!)

17. Fume hoods, do not… …open more than one horizontal window! …block the supportive air stream with large objects or dozens of bottles! …use the fume hood for storage purposes! …use multi-outlet power strips! …leave your experiments unattended for a longer period of time!

18. Fume hoods: Controls green: fully operative; orange: low air flow mute alarm light open/close sash maximum air flow reduced air flow (night mode)

19. Ventilation: day vs. night acoustic alarm green: day mode, air volume okay (active from 7 am to 8 pm, can also be activated manually for 2 hours) air volume too low night mode, reduced air volume (active from 8 pm to 7 am) Please keep doors and windows closed! Otherwise the dynamic ventilation system can‘t operate properly and thus, fume hoods might not retain hazardous substances anymore. With NO warning!

20. Fume hood vs. ventilated cabin any kind of experimentsvery restricted usability (low air flow)

21. Vacuum installation increased safety, temperature controlled, ready for use controls (on/off for both pumps, acoustic alarm, mute alarm)

22. Electricity in the lab green: emergency power supply (no UPS!)fuses and residual-current device (“FI”) Check your installation before turning on again your devices! usually reserved for refrigerators and freezers

23. Night room and solvent distillation Fume hoods and cabins are equipped with argon fire extinction systems. Get out in case of alarm! All joints and tubings must be controlled daily! Heating mantles should be replaced by Heat-On attachments. Usage of AQUAcontroller is mandatory! What is missing here? A floor drain! 

24. Supply: transport routes The corridors on the ground floor MUST NOT be used for any transport of chemicals or any other materials! Use the basement floor for these transports! The doors there open automatically! Use appropriate containers and carts! Block the elevator when transporting hazardous materials or compressed-gas cylinders

25. Supply: How to block the elevator sensor for transponder 1.Activate sensor and call elevator. (Door opens.) 2.Load elevator and choose destination. 3.Activate sensor again. (Door closes and elevator starts moving.) 4.Take the staircase and activate sensor on the destination floor. (Door opens.) 5.Unload elevator and activate sensor again. (Elevator gets unblocked.)

26. Solvent supply and storage Ex zone !!! Use the exhaustion!Keep doors closed!Only 75 kg per base!

27. Gas supply You will never run out of Argon without warning! Alarm! (hydrogen leaking)

28. Waste disposal The rooms DON‘T have a fire extinguishing system! DON’T store flammable solvents outside cabins, fume hoods or cabinets, in order to avoid explosive atmosphere! Solid lab waste has to be disposed into the metallic dustbin! With the lid CLOSED! (Therefore, only small blue barrels can be used.)

29. Please don‘t forget… …to close the taps of the lab washer after each use. …to control all cooling water outlets before leaving the lab for a longer period of time. (It’s a good idea to unplug both cooling water connectors when cooling is not required. But never ever unplug only one of them! And always check if the tap is closed!) …to store safely all flammable liquids before leaving the lab. …that in our business even the smallest mistake can cause terrible damages or injuries. Our building has already seen fire and inundations. The next time it might destroy your working place. Please take care!
