And they do have a chart as I mentioned. But they also clearly say in their brochure that those gloves should be removed and replaced if a chemical even splashes on them. Monona

Jessica,As per the replies to your request, the consensus is that you should work with the data as "manufacturer specific" and not "generic."Here are two helpful information sheets from W. W. Grainger, Quick Tips #166 & #191 on chemical resistant gloves.Also, you may want to speak to someone at the Technical Service Department of any one of the following manufacturers and Grainger for help.
- Ansell
- Grainger (distributor)
- Magid Glove & Safety (manufacturer/distributor)
- MAPA
- North by Honeywell
- SHOWA
Good Luck!Be Safe and Stay Healthy!All My Best,John B. Callen, Ph.D.3M Personal Safety Division - RetiredACS/DCHAS Founding Member(312) 632-0195

you also have to take into account the glove thickness, which could vary by brand. Some nitrile gloves are 4 mm, others 8 mm...I don't think I would want a generic chart, so much depends on the mfg. And they have quite a bit of incentive to get it right...$$$$$My two cents...

If you do a Google search, you'll end up with generic information that will be unreliable - depending upon which glove has been specified.Suppliers and Google will provide generic "data" but nothing I would rely upon when you really need to confirm adequate protection.It's late and I can't remember the name of the organic chemist who started the testing work at Ansell. He developed the first spreadsheet, which later turned into their database. When I ran into a new molecule that was going to be tested for toxicity as an investigational new drug, if he could not refer to a very close analog to provide protection, I could send him a sample and he would test to provide a recommendation. It depends upon what you are trying to protect against. Is a generic, possibly diluted level of protection adequate or are you trying to protect from a true hazard?
