Good afternoon DCHAS,
It came to my attention recently that hydrofluoric acid isn’t the only chemical requiring treatment with calcium gluconate gel and segregation from glass. A brief conversation with a cleanroom friend confirmed a few I found online, but
does anyone else have any chemicals, mixtures, or resources for identifying chemicals with comparable hazards as hydrofluoric acid?
Below I’ve listed the names of the chemicals with SDS references to HF burns, use of calcium gluconate gel, and/or that they react with glass. Any additional insight, input, or suggestions would be greatly appreciated.
