Chemical Compatibility is the “Fourth C” in evaluating cleanroom gloves. This video discusses the compatibility of each substrate when faced with chemical exposure, and sheds light on safety practices along with the critical difference between light chemical splash exposure and full chemical immersion.

The Fourth “C” when selecting the most appropriate glove is the Chemical Compatibility. And there are basically two types of chemical families. There are acids and there are solvents. A PVC glove is really good with neither. A latex glove is good with mild acids, but it's not good with solvents at all.
A nitrile glove is most chemical compatible with acids and solvents. But just a little contact about what we mean when we say chemical compatibility. When we say chemical compatibility, we mean light splash exposure. We mean touching something.
We do not mean immersion, OK? There are some chemical processes that require the operator to immerse their tool, to immerse their hand, into a chemical process. And so you want to make sure that you clarify with an operator that thin walled gloves are chemical compatible just for splash or for casual chemical exposure, not for immersion.
If the operator needs to immerse their hands into a chemical bath or they have prolonged direct chemical exposure, they still should be wearing the appropriate cleanroom glove underneath. And then when they go to those chemical stations, they'll have a very thick walled chemical glove that they'll put on.
So think of it like when you're cleaning your dishes at your sink. When you're doing just a normal cleaning, you'll probably not even wear a pair of gloves. You'll just be with the sponge. But if you have something that is corrosive or you've got a clean Brillo pad, you're going to wear a thick glove, right?
You're going to wear a thick glove to protect your hands for the chemical exposure. Same thing in a cleanroom. So you always need to qualify chemical compatibility. These gloves are primarily designed to protect the product and the product.
They're only for limited chemical exposure. And if anyone asks about chemical compatibility and they're serious about it, they should really be in just one material. They should be in nitrile. And then you always want to make sure that they have that chemical handling glove
that's a very expensive glove that stays at the chemical handling station. Operators don't like to wear them because they don't get good tactile sense, right? But those very thick gloves provide the kind of chemical compatibility you need for immersion.
Thank you.
