I teach introductory microbiology at a community college, and have this problem.  I do tell them at the beginning that if culture spills on their device, it will have to be autoclaved, and that most phones don’t even survive a trip through the washing machine—I know from experience.


Since many of them are returning students (it is an evening class), I tell them they are welcome to step outside of the lab to call or text, after removing PPE and washing their hands.  It hasn’t come up with me either, but I’m prepared to tell them that the alternative to autoclaving is that they carry the microorganisms around with them.  There is a large clock with a second hand for anything that requires timing.

It’s becoming increasingly difficult to keep undergraduates from using their electronic devices in the teaching lab.  We disclaim that any damage is not the responsibility of the institution.


Here’s the question:  What if something hazardous is spilled on the device and it can’t be decontaminated?  Does the device become hazardous waste at that point?  What if the owner isn’t willing to give up the device for disposal?


This scenario hasn’t presented itself – yet!
