<p class="MsoNormal">Early this summer, when the university began allowing folks back on campus, face masks were required. In fact, the university even provided a multi-layer cloth mask to ALL students, faculty, and staff. Most people use that mask, while
some have found other styles. I did not want anyone removing or replacing that mask to enter the cleanroom, so they continue to wear their own mask for the cleanroom. Frankly, I recognized that any user-provided mask (cloth or paper) may not be very effective
at particle filtering, but there are worse regular practices that compromise the cleanroom. We only double-mask (add a standard cleanroom snood) when the user’s mask does not cover all facial hair. I have no data to support our approach, but it seemed to
be a reasonable compromise to the current situation. The biggest problem has been the increased fogging of safety glasses. Social/physical distancing is still promoted, but poorly practiced.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I may be naïve, but I believe standard cleanroom protocols, frequent wipe downs of workstations, occupancy limits, and the high air exchange rate significantly reduce the risk of spread even when social distancing is problematic. Our cleanroom
reopened for limited use in May, including several lab courses during Fall Semester. To date, I am unaware of any lab member infected while using the cleanroom – although a few have been elsewhere.<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-CA">Now that N95s are starting to become a bit more accessible, there has been some recent discussion within our labs about whether to adopt an N95 mask policy for new users and when distancing is a challenge.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">So far we have just been wearing the standard cleanroom style masks.<o:p></o:p></span></p>
