During staff hours, a buddy is not required. Fortunately, all of the low/high pH work is confined to one bay in our fab and, with HD cameras, enforcing the buddy system is relatively straightforward.</div><div><br></div><div>The requirement for a buddy is simply that they're a trained user who must be in the fab at all times while work is in process. We do not require that they shadow the person conducting work. Staff hours are posted during orientation and holiday/buddy reminders are broadcast through email and on a flat screen in the gowning area. So, our users are hopefully respecting and aware of when a buddy is required.</div><div><br></div><div>Best,</div><div>Noah<br><br><div>Noah Clay<div>Director, Quattrone Nanofabrication Facility</div><div>University of Pennsylvania </div></div></div><div><br>On Sep 29, 2016, at 15:30, Michael Hume <<a href="mailto:michael.hume@ualberta.ca">michael.hume@ualberta.ca</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">Dear Colleagues, <div><br></div><div>We are in the process of re-evaluating our after-hours policies, specifically in regards to wet chemical processing (eg. HF/BOE/KOH/TMAH/Piranha cleaning). Historically, we have not allowed these processes after hours, primarily due to safety concerns.
