We use HF is many of our labs and I recommend that you purchase ready made HF spill kits, we get ours from New Pig which supplies all kinds of spill response equipment. One of the nice features is the liquid for decon changes color when
neutralization has occurred. Not sure about the concentration but I’m not a big fan of preparing these kinds of spill response materials in house.

Subject: [DCHAS-L] HF working surface decontamination solution - recommended concentration or alternate?
Hello,
Does anyone know what percent solution of calcium hydroxide would be appropriate for decontamination of working surfaces where HF has been used, or small spill of HF known?
Or is there a better solution anyone can recommend?
Thanks,
Rachel
