<div dir="ltr"><p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:Aptos,sans-serif">Dear Labnetwork Community,</p>

<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:Aptos,sans-serif">I am writing to share a new safety initiative following our
recent short presentation at the UGIM conference at Stanford. We have launched the <b>OneNano
TMAH Taskforce</b> and would like to invite members of this community to
connect and share their experience with us.</p>

<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:Aptos,sans-serif">The goal of this taskforce is to develop evidence-informed,
collective guidance for the safe use of Tetramethylammonium Hydroxide (TMAH)
and TMAH-containing solutions in academic and R&D laboratories. Our primary
focus areas include hazard awareness, exposure prevention, and emergency
response.</p>

<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:Aptos,sans-serif">As managers, directors, and operators of university
microfabrication and cleanroom facilities, you have valuable experience and
perspectives that can help inform this shared safety effort. We hope to bring
together professionals working with TMAH to exchange knowledge and experiences,
helping to promote safer practices across our community.</p>

<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:115%;font-size:12pt;font-family:Aptos,sans-serif">Participation is entirely voluntary, and contributors are
welcome to engage at any level that fits their availability. If you or members
of your team are interested in contributing, you can join the taskforce by
filling out this short TMAH Taskforce Registration Form: <a href="https://docs.google.com/forms/d/e/1FAIpQLSfT4nsJZasVJCLn3Iogu8IZdYvqO4ctUJuRxcZEdPvrFp4L1A/viewform" style="color:rgb(70,120,134)">https://docs.google.com/forms/d/e/1FAIpQLSfT4nsJZasVJCLn3Iogu8IZdYvqO4ctUJuRxcZEdPvrFp4L1A/viewform</a>
