Hello All,
I have a question that I cant get answered anywhere, I unload and load bulk corrosive chemicals Nitric 70%, Sulfuric 93%, Hydrofluoric 49% and Caustic 30%,50%.
What reusable suit material would be the best to use for each chemical? Neoprene or PVC? Different web sites gave conflicting answers, I did check all the SDS's and they state use "impervious" PPE?
Thanks
