In this microbiology laboratory, visitors would walk in and drop off patient specimens. People would sometimes get burned because they didn't realize there was a hot sterilizer on the counter to the right of the plates (they are outsiders who are unfamiliar with the lab). After not having success with "be careful" signs, a staff member asked maintenance to install the clear plexiglass. This also helps prevent specimens being dropped off in the wrong location (they really want them being dropped off further to the left).
