<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">When we returned to work after the first lock-down, we asked ourselves what to do regarding masks/face covers.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Then I did a very simple experiment to check by myself how effective is a face-cover to contain the particles we generate during normal respiration or talking. See attached summary.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Today our policy is: every user comes with his/her own mask and must put the face cover over it. This “two layers” solution is more than enough inside the clean room (plus as much distancing is possible).<o:p></o:p></span></p>
