Always follow these signs. You can knock on the door and, if someone answers, identify yourself and he or she will either tell you when you can come back or will assist you in entering the room. In some cases, you may be shown where you can safely walk in the lab. If that happens, do so only when a researcher is in the lab or specifically follow the researcher's instructions if you are permitted to access the room when it is unoccupied . Most of the lasers in the College are on the D level of Hildebrand, Latimer and Giauque with a few in upper Hildebrand and Latimer.
Autoclaved bags are safe for disposal in the regular trash.
If assisting with a laboratory clean-out, do not throw out any biohazard bags that do not have autoclave tape and show that they have been sterilized. Super conducting magnets are in use in several rooms in the College mostly on the D level of Latimer, Hildebrand and Tan Halls. These magnets are very powerful and, if you get too close, can harm people who wear heart pacemakers or have any metallic implants as well as pull keys or tools out of a person's hands and erase magnetic stripe cards such as bank cards and credit cards. Besides danger to you, any metal you have on you could potentially affect the magnetic field and do immeasurable damage to the research. These magnets have safe areas marked around them by striped tape.
