General Guidelines:The chemistry lab was designed to be a safe, clean, easily-maintained research environment accessible to individuals with the appropriate training. Keep this in mind when you are using it. Access to the chemistry lab is limited to M-F 8am-8pm. To gain access for any other times, please contact Tony Nolla (nolla@cs.cmu.edu). 1. Follow the togging in/out procedure for entering and leaving the chem. lab. 2. Be aware of others in the lab. Let others in the lab know when you enter so you don't surprise them later. In general, COMMUNICATE! 3. Lab coats must be worn at all times, except for equipment maintenance. This is to keep the lab clean and protect you from accidental chemical splashes. 4. Use the buddy system when necessary: a. if you are a relatively new and inexperienced user b. if you are working after hours with potentially dangerous equipment, etc. 5. If you observe equipment malfunction or a hazardous condition in the lab please report it to appropriate personnel for that equipment. Each equipment has a superuser assigned to it. 6. After using any of the equipment or using the wet benches for chemistry, make sure you clean up the area and leave it in its original condition. If the previous user left the area unkept, please email the superuser for that specific equipment. 7. Users are to enter the lab only through the togging room door. Do not enter through the utility access door, the doors are alarmed. 8. The supplies in the lab are not for general use outside of the lab. 9. Dispose of all trash in its respective place (broken glass in the glass waste container). If trash cans are full, please put them outside in the hallway. 10. Keep all doors closed while working in the lab. 11. No food or drinks are allowed in the lab. Specific Guidelines for Wet Chemistry Users: 1) Store all chemicals in the acid/solvent cabinet, not on the lab benches. 2) Gloves must be worn at all times. 3) No shorts or open-toed shoes. 4) Wear appropriate head-gear when necessary. 5) All bottles/beakers/jugs containing any form of waste, acid, or solvent must be labeled. Labeling equipment is located in HH1212. 6) In order to keep chemicals in stock, it is the responsibility of the person who finishes a bottle to replace it from the cleanroom stock and to notify George Lopez (glopez@cs.cmu.edu) via email of what has been used. YOU MUST email glopez@cs.cmu.edu so that proper inventory can be kept.
