My advice about the thin medical-use Nitrile examining gloves is: "get thee to the manufacturer!" And the bigger the manufacture, the better the studies they usually have. In training I cite Kimberly Clark's permeation data and show them the statement in KC's own brochure that says clearly the gloves are not to be used for protection against chemicals. They are examining gloves. The brochure states that these gloves are only good for incidental chemical splash protection and as soon as a chemical splashes on to the glove they should be removed immediately.
They have a permeation chart that shows resistance for a few things, but they still don't recommend them. Many chemicals will go through in a minute or so. And this is true of all of the thin mil examining gloves. Watch out for suppliers of gloves who do not actually manufacture the gloves. They may make claims that are not supported. Watch out for gloves marketed for a specific purpose (e.g., tattoo gloves). Unless you are doing tattoos in the lab, these are a no, no. It is necessary to go to the heavier nitrile and other polymer-types of gloves that are designed for chemical handling. And even then, consult the manufacturer's ASTM methods permeation data chart. Nitrile is wonderful stuff, but there are some chemicals that go through nitrile without changing the glove's appearance. You need a selection of gloves specifically known to be a barrier for the various chemicals you use. The only people who know what their gloves can be used for safely are the people to made them and tested them. So your research has been done for you. You only need to download it from each major manufacturer. And the charts have a technical number on them somewhere that you can call if you have questions. ------------------------------ Monona Rossol Arts, Crafts, & Theater Safety New York NY (212) 777-0062 ------------------------------ ------------------------------------------- Original Message: Sent: 10-17-2019 12:19 From: Ana Silva Subject: Nitrile gloves We are currently re-assessing the type of nitrile gloves we use daily in handling of collections, and I would like to open up a up-to-date discussion about the types and choices taken in the community. This re-assessment was prompted by a concern related certain components in the gloves affecting the metal surfaces (halides or sulphur accelerants). Does anyone knows of studies concerning the effects of certain nitrile gloves in object handling? I have recently looked into the N-Dex brand from Showa, but it seems they are no longer using the specific N-Dex reference anymore. I am also curious about the performance of their new biodegradable gloves. Thoughts on the new types of gloves they offer? How do the usual medical-, food- or industrial-grade nitrile gloves brands such as Kimberly-Clark perform? ------------------------------ Ana Silva National Music Museum Vermillion SD ------------------------------ Reply to Sender : https://community.culturalheritage.org/eGroups/PostReply/?GroupId=481&SenderKey=6ea82495-27fc-43b2-804c-b5004e98b727&MID=9173&MDATE=756%253e46546%253d&UserKey=d16eaa87-0f69-494b-9f2f-303dbc1222e1&sKey=fab9aa4f27a04c5d876e Reply to Discussion : https://community.culturalheritage.org/eGroups/PostReply/?GroupId=481&MID=9173&MDATE=756%253e46546%253d&UserKey=d16eaa87-0f69-494b-9f2f-303dbc1222e1&sKey=fab9aa4f27a04c5d876e You are subscribed to "Global Conservation Forum (ConsDistList)" as [email protected].
