I wonder if your bottles come from the same supplier, look the same, and have chemical name buried into huge DANGER, HAZARD, WARNING symbols. I definitely had some bottles (not pointing fingers, but I have some specific companies in mind) where finding chemical
name required literally 2-3 minutes of reading. Can you share bottle pictures to see if that is the issue?

possibly with different color markers. Switching one of chemicals to a different brand so bottle has different shape and label style...

Hi!</div>

We recently had a couple of occasions where users had mistakenly used Hydrofluoric acid in place of Hydrochloric acid during RCA cleaning. To avoid this, one of the suggestions we have received from our OLSEH is to store HF in a different coloured bottle (currently
all acids are stored in white translucent polypropylene bottles which are properly labelled). Accordingly, we had considered storing HF in opaque, brown colour HDPE bottles. However, that was not deemed acceptable by a section of users saying bottles should
be translucent so that acid level inside can be judged.</div>

Could you please let me know how small quantities of HF are stored in your respective fabs. Is there any regulation governing storage of HF, so that we could implement the same.</div>
