Really, were going to pick on me for saying HCL instead of HCl. I'm not going to go any further acknowledging inappropriate off topic behavior. However, I am going to continue to stand on my head over student safety. Read the whole message, the whole entire thing. I believe my exact word wa s "outlandish" and how you can insert random disaster at any point. Risk assessment is part of the learning process, true, part of that should be proper PPE which baring certain circumstances should be gloves, glasses and adequate clothing coverage at all times. The student is not ready to make that decision on their own until they can truly appreciate the benefit of PPE, ie. "thank god I wasn't wearing sandles when that flask boiled over".

It could be argued that it is prudent to wear gloves all of the time (just as we mandate splash goggles all of the time) but for me, the arguments above about cost, comfort, lack of need in many lab situations, a nd the possibility of using the wrong glove material all argue for a more tempered, occasional use of gloves.=A0 =A0Of course, one idiosyncratic allergic reaction by one student out of a thousand can lead to universal CYA-motivated use that, in my judgment, could end up doing more damage than good over the long haul for the other 999+ that follow.=A0 Alas.

As the staff of the Chemistry & Biochemistry Teachin g Labs, we have been asked to propose ideas for saving money, as budgets are only getting tighter over the next few years. One idea proposed is that we stop providing gloves ad lib. to students, but have them buy & bring their own. We currently supply eith er nitrile or PVC examination (thin, single-use) gloves in our labs.

Do you provide/require gloves for student labs?
