<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">A few months ago during the height of the pandemic one of our lab users who also works in another cleanroom in our local area had mentioned that they had disabled the air shower from the gowning
room to the main cleanroom as a covid precaution. Following that, we did the same at Caltech.

<p class="MsoNormal"><span style="font-size:11.0pt;color:black">If your cleanroom has an air shower between the gowning area and main cleanroom, I would like to ask a few questions.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">Did you turn your air shower off at any point as a covid precaution?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">If so, have you resumed using the air shower?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">Did you ever get any direction from your safety department on whether to use it or not?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">Have you found a noticeable difference in how clean the lab is when it is in use vs disabled?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;color:black">As we are ramping our research activities back up on campus, we are looking for guidelines from other labs on best practices, and this is an area of interest.</span><span style="font-size:11.0pt"><o:p></o:p></span></p>
