<div>Hi Nava,</div>
<div><br>
</div>
<div>We have yet to come up with a formal standard operating procedure for our dedicated piranha hood. I suspect we will very likely proceed in a manner that is identical with John's description after letting the solution cool down for some minimum amount of
time. The hood is equipped with a proper aspirator and the facility is served by an acid waste neutralizing system. </div>
<div><br>
</div>
<div>Best regards,</div>
<div>Vito</div>

<p class="MsoNormal"><span style="color:#1F497D">I’m in favor of aspirating it from the bath into a significant stream of running water. That would, of course, go to an acid-neutralization system.

<p class="MsoNormal"><span style="color:#1F497D">The big advantage of this approach, of course, is the cooling as well as diluting effect of the water stream. It is important to be sure the aspirator and associated tubing will withstand the heat and oxidizing
