<p class="MsoNormal">I echo previous comments. I know of no cleanroom clothing or lab coats that are appropriate for chemical protection. In most cases, cleanroom clothing is seldom considered as PPE (exception: flame resistant fabric). It is not to protect
people, rather protect the cleanroom<b> <i>from</i></b> people.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We use standard cleanroom bunnysuits, a polyester blend with 1-2% carbon, which provides some minor ESD protection. The material is also used for cleanroom frocks/lab coats. For those parts of our lab that are not in the cleanroom, our
EHS department suggests flame resistant lab coats, but I haven’t done so, yet.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For chemical protection, we use Tychem-SL full-sleeve aprons (now branded as Tychem 4000). They are polypropylene coated Tyvek. They are re-usable, but disposable. I insist on full-sleeve aprons. Surprisingly, there aren’t many options
available. These actually offer better protection than vinyl and are lighter and much more tolerable when wearing for extended periods of time. The wrist elastic isn’t really great for the cleanroom, but I accept it anyway.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also have Tyvek bunnysuits on hand as a backup – especially for contractors and personnel involved with tasks that are likely to damage garments. And, I have some Tyvek lab coats, used occasionally for large tour groups.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">BTW, I know some industry facilities require flame resistant Nomex cleanroom bunnysuits for maintenance staff – I used to work for one.<o:p></o:p></p>

<p class="MsoNormal">Hi Everyone, I know that this had probably been discussed before, but can you tell me what material/vendor you have for your lab coats? It looks like what we’re currently using are more suited for ESD protection for the parts and not necessary
the best for protecting users from chemical. The chemical lab coats we have here would seem to shed and not be compatible with cleanroom. Is there some sort of hybrid that you use? Or maybe just something that protects the users a bit more and still suitable
for cleanroom? Thanks!<o:p></o:p></p>
