Nomex is not chemical resistant!
I had a driver delivering sulfuric acid to a refinery in Phila. He was wearing his full PVC chem suit while the receiver wore a PVC Jacket and hard hat w/ face shield.
When the hose broke, the acid struck the receiver in the side of his head blowing his helmet and face shield off. This was an older refinery and this spot had a 'horse trough' full of water instead of a safety shower. The receiver jumpped into the tub without stripping off.
Adding water to acid makes a huge heat reaction, the shipper estimated the acid inside his chem jacket reached over 400 degrees when the water hit it. [my driver said he did not yell until he hit the water!] and he ended up needing skin grafts on his neck AND on his butt where the acid ran down the chem jacket and ate thru his nomex and clothing...
Heat & sweat IS part of using PPE but consider the alternmatives...
They do sell a vest full of pockets for ice packs to be used in total encapsulating suits [yup, keeps the farts in!] since they take so long to don and remove...
I know alot fo my acid drivers used to 'test' the shower leaving it run on hot days until the water temp got cold enough to cool them off.

Just to double check, I'm talking about TWO sets of clothing, a set of OVERALLs and a CHEMICAL suit worn in conjunction with each other. -
Hell I haul water on a temp. basis doing weekend work (may go full time soon) and I just wear jeans and a t-shirt (hardhat of course). When I delivered Frac equipment on a step deck I still wore the same. I've yet to have ANYONE say a word to me as to needing anything else on.

i drove for the oilfields,
Nomax are hot, they don't breath much
Respirators are for when you come in contact with H2S gas. I can kill you fast. you will wear a monitor on your shirt that detects it. And only have to wear the mask when you come in contact with the gas. -
I go into refineries a lot and have to wear either nomex coveralls or long sleeve shirt and pants that are nomex. I only pick up spent catalyst but would rather have it than not. I wear the carhart brand and its good but yes you will still sweat. Its a must for anybody in a refinery and although i dont like it, would rather have it on. Any flatbedder can tell you that we are usually stuck wearing a hard hat, safety glasses, jeans, boots, ear plugs, safety vests and of course nomex coveralls. This is because we are always on a job site somewhere.

Currently around the rigs we are required to wear level 3 FRC which is cotton or canvas that has been treated with FRC chemical. They do not require us to wear a respirator, Hardhat, safety Glasses, Steel toe boots, either a jump suit or pants and shirt. I currently unload in Occidental and Exxox at the rigs daily, at least for now. I also have to have a H2S dector affexed to my hardhat. Alarms mean evac to a designated safe area till the all clear or you get futher direction.
The Ruffnecks may have respirators I do not know, but none of us drivers carry them. -
