<p class="MsoNormal">We have had this problem in the past due to a lot of the chemical bottles look so similar, and the labeling of the product can be very small.<o:p></o:p></p>
<p class="MsoNormal">As a “best practice” we label all manufacturer bottles of anything containing HF with a “Need A Buddy” sticker as soon as it arrives to our facility.
<o:p></o:p></p>
<p class="MsoNormal">We also have a “need a buddy” rule when you pour HF, the label also acts as a reminder.
<o:p></o:p></p>
<p class="MsoNormal">Hope this helps.<o:p></o:p></p>

<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;color:black">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.<o:p></o:p></span></p>
