<div text="#000000" bgcolor="#FFFFFF" class=""><p class="">Hi all,</p><p class="">I'm curious how the different labs out there deal with
photoresist safety. I know that the fumes can be toxic, but it is
difficult to deal with completely. We have all of our spin
coaters under a canopy exhaust that captures a lot of the fumes,
but you can still smell it. Do others put the coaters in a fume
hood? Perhaps use respirators? Or is it not that big of a
concern if you capture most of it?</p><p class="">Thanks,</p><p class="">Nathanael<br class="">
