Personally, I think you’re much better off providin g safety equipment, and reducing costs in other consumables, etc. by requirin g the students to pay for what they use.
At more than a slight risk of sounding like an 80-year-old talking about ‘the good old days’…
When I was a graduate student, we required all undergrads to inventory all of their lab equipment and pay for replacement of any broken/missing stuff. I’m sure you have a lab fee which is mean t to supply certain things. Examine that to ensure it really does cover th e cost of what the average student consumes, but for breakage, loss etc. the individual responsible can be required to pay.
Also, as far as safety goggles & safety glasses ar e concerned (not really wanting to re-open that discussion, folks!!) If your department permits safety glasses, you can have your booksto re stock the el-cheapo face-wide ones (with sideshields, I hasten to point out) and the full-coverage goggles. But your stockroom could have all sorts of neater-looking safety glasses (again, if your policy perm its these) available for a slight premium. This income can be used to off set some of the lab costs (although I have been places where the ACS student affiliates did this as their fundraiser).
Just a couple of suggestions. They may or may not work with your department/university policies.

I'm really sorry if I c ome across a little harsh here, and oddly generally the opposite stance I take; but WERE TALKING ABOUT STUDENTS....KIDS!!! Let me ask you this, first its OK to handle 0.1N HCL fine no real dermal hazard with a quick rinse, but now t he bio department adopts your successful policy. Now the kid gets someth ing on his hand that doesn't sting a bit...but what he really took home was a little ecoli they were working with, which, although harmless, mutates...li ke ecoli likes to do and boom...you got yourself an outbreat. OK, a litt le outlandish....but insert disaster at any point...it could happen and chance s are something bad will happen, what is more likely is little suzy's parents suing you for the little red mark left by the acid and you can use your new ly saved money to settle with them. You can warn them about the hazards of working no glove...but this is America and they will win.

We make gloves available, but I personally encourag e students to wear them only in situations where they are warranted. In my judgment, in many labs the chemicals in use provide no significant skin haz ard, especially when a quick rinse with readily-available tap water is possible even in instances where perhaps some dermal hazard might exist (for extended exposure.) The skin is a pretty good barrier, but there are surely chemicals that can destroy and/or penetrate skin. For some dermal hazards, the gloves that might “be routinely available” in lab may not provide protection, either, so unlike splash goggles that provide virtu ally all-encompassing eye protection, “gloves” might not protect the skin depending upon the chemical and the glove. Wearing t he wrong glove may be worse than wearing no glove. And, this email threa d is about “student labs” where many of the most dangerous der mal hazards would be avoided in the first place. (HF in general chemistry? I think not!)
Also, unlike goggles, gloves are disposable, which incurs the cost that prompted this email thread. I don’t “discourage” glove use, but (I think that) some students use th em more routinely than others, and perhaps more than necessary (perhaps relate d to bouts of chemophobia that may not be warranted). Some students realiz e that gloves become uncomfortable to wear after awhile. Safety overrides comfort (as with some goggles, for some students), to be sure, bu t when there is no need for gloves why endure discomfort? Gloves may or may not hinder manipulations; in principle they shouldn’t, but inexperienced users don’t make what others might consider “good judgment” in many situations.
Finally, I recall reading (about 40 years ago) some human behavior study that indicated that some drivers drove faster when wearing s eat belts (when these were new devices in cars) since they “felt safer 221; wearing the seat belt and therefore “felt safer to drive faster.” (This was hardly the intended effect of wearing seat belts, and I’d guess not a universal response for all personality types.) But, I wonder, if some students won’t feel somewh at less need to be careful about spilling solutions or solvents when they are wearing protective gloves? Just speculation; no data, not even pseudo-data like an anecdote!
It could be argued that it is prudent to wear glove s 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. Of course, one idiosyncrati c 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. Alas.

We provide them in our undergraduate chemistry/biochemistry labs, amid some gnashing of teeth over the cost! We do require students to purchase their own safety goggles. I don’t know what other undergraduate lab classes provide – biolo gy, geology, etc.

to propose ideas for saving money, as budgets are only getting tighter over
next few years. One idea proposed is that we stop providing gloves ad lib.
students, but have them buy & bring their own. We currently supply eith
nitrile or PVC examination (thin, single-use) gloves in our labs.
Do you provide/require gloves for student labs?
