<p>Hi all,</p>
<p>For those of you who allow hot phosphoric acid etching in your
facilities, I would appreciate any safety or operational tips you
have. For us it would need to be a hot-plate process, and I want
to make sure we are taking a cautious approach before allowing
heating of phosphoric up to 160°C. I did some quick searching of
the lab network forum and it looks like we should at least be
cautious of the acid apron material due to the temperatures
involved.</p>
<p>Please feel free to email me directly or reply to the thread with
any advice you have to offer (even if it's 'don't do it!').</p>
<p>Thanks,<br>
Nathanael</p>
