At the bacteriology laboratory
Mrs. Riemer: Sunny, this is the student lab for various bacteriological examinations. You are going to practice the tests here in this lab. Be careful not to carry the contaminated materials here and there, and it will cause unnecessary contamination through the entire lab.
Throw all the contaminated materials here in the bucket, and you must wash your hands before you leave the room.
