Disposable gloves

I'm wondering whether we should be disposing of disposable gloves every time we use them?

After all, we're not in an infectious diseases unit!

It seems to me that we shouldn't be throwing a pair of disposable gloves in the bin after we've used them, without curing any uncured resin, otherwise we're sending a toxin to the tip. But then, if we cure the resin on the gloves after we use them, then they're non-toxic, so shouldn't we be able to use them again?

I note that the PVC gloves I use become sticky on the inside whilst I'm using them. Its as though the resin is penetrating through the gloves, so maybe PVC gloves are no good?

Disposable gloves

Your thoughts on this are welcome.

It depends on what you are using them for.  Protection against COVID or chemical and they should be replaced after each use.

Thanks for replying Charles

Well, this is chemical, but it seems to me we can re-use disposable gloves used for handling UV cured resins, provided we cure the resin on the disposable gloves.

Agree?

Is there a good reason why not?

In an industrial environment PPE gloves are almost always considered single use.  The intent is to protect your skin from contact with hazardous chemicals or biologicals and resins are usually considered to be hazardous.  I'd check with Prusa or your resin supplier to see if PVC gloves are acceptable for use - nitrile might be a better choice and those are available just about anywhere in the US.

I don't accept the proposition that because everybody else does it that way, that that is the best way to do it. I have worked in corporate environments long enough to know how dysfunctional they are.

A big reason for an industrial environment to specify that PPE gloves shall be single use is for elimination of risk, and I understand that. However, I propose that we engage with risk, not avoid it. We should perform a risk analysis if necessary. So, here I am collecting information. Is there a good reason, not to cure any resin on what would normally be single use gloves, and re-use them?

Yes. Liability. Unless you can guarantee that all irritants are prevented from skin contact and that the glove is intact, no manufacturer is going to say it's OK. That's a very good reason not to recommend the practice.

As an individual, you can do whatever you want. Smoke, drive without a seatbelt, tear tags off mattresses. Just don't expect to see a corporation recommending it. Lots of people reuse single use items. If you feel you can do so safely, go for it.

@mbarr

Have you worked in an industrial or research environment?  Not many, aside from janitorial folks, need much use of PPE in corporate environments.

I've worked in both industrial and research environments with exposure to biological organisms and hazardous chemicals and have learned that there is often a very good reason for PPE, sometimes the hard way.

The cost of gloves is low enough that it seems silly to try and re-use them, but if you feel differently, no one will try to prevent you from doing whatever you want.  Good luck with it.
