--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.orgGood 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.
Sulfur Hexafluoride
Ammonium Bifluoride
Ammonium Fluoride
Boron Trifluoride
Buffered oxide etchant (BOE)
Diethlyamino sulfur trifluoride (DAST)
HF-Pyridine Complex
Hydrofluoric Acid (HF)
Knolls Reagent
Lithium hexafluorophosphate
Sodium Fluoride
Sulfur tetrafluoride
Tetrafluoroboronic Acid
Xenon Difluoride
(My first request to DCHAS)
Best,
-P
