<div dir="ltr">Hi Laura!<div><br></div><div>I agree with Andy - I've seen some NPS sites that placed their study skins in the polyethylene tubes. They've been in controlled museum storage for several years now and although I've never performed a specific survey, I haven't noticed anything out of the ordinary. Not sure the thickness, though. </div><div><br></div><div>As an aside, these were placed in bags also with the intention to protect staff, but this is not necessary if you're wearing PPE and practicing good hygiene. For anyone handling these collections, wear nitrile or latex gloves and wash your hands immediately after removing gloves (after you're done working). Vacuum work areas with HEPA vacuums. I understand why you're needing to place them in the tubes, I just don't want folks worried that it must be done across collections. </div><div><br></div><div>And now, taking this chance to plug an upcoming panel at the next meeting of the American Institute for Conservation in May. The panel is Arsenic in Collections and will feature case studies from institutions who are successfully managing/working with collections that have arsenic as an intrinsic component. Friday, May 24th at 10:30. </div><div><br></div><div>Best,</div><div>Fran</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 7, 2024 at 7:32 PM Abraczinskas, Laura <<a href="mailto:abraczi1@msu.edu">abraczi1@msu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg42340786901375021">

<p class="MsoNormal">Not sure that 2ml or 4ml would make much difference in that regard. 4ml may be a little more durable to puncture by spiny or rough objects so may be worth the investment. We use the same material we use for packing loans so that we only
have to order one kind and have a large stock of it. We use the 4ml.<u></u><u></u></p>

<p class="MsoNormal">Dear NHColl list members,<u></u><u></u></p>
<p class="MsoNormal">I am seeking advice about sealing specimens within polyethylene bag “tubing” for temporary storage during a collections move. This is an example of the “tubing”, which is a roll of open-ended polyethylene bags that contents are sealed
within by use of a heat sealing machine. (We have a tabletop impulse sealer).<u></u><u></u></p>
<p class="MsoNormal"><a href="https://urldefense.com/v3/__https:/www.uline.com/BL_200/Cleanroom-Poly-Tubing__;!!HXCxUKc!ymc0MDXRapx2VPSVPiw6BGJ90-vZ8WpkGYIMNJceBoheXyiFf1pKrMMTpCWM380kKGUzsfCzs0OS3XXVJw$" target="_blank">https://www.uline.com/BL_200/Cleanroom-Poly-Tubing</a><u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">The Michigan State University Museum is preparing for a temporary move of the dry vertebrate collections before a building-wide HVAC renovation project begins! Specimens will be temporarily stored off site for about 18 months. Specimens
will not be stored in their usual cabinets but packed into boxes or other containers and secured at an art storage facility with climate control.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">We are wondering about use of this product for bird and mammal skins or taxidermy mounts, or other dry specimens. The vendor has asked that we bag and seal anything that may contain arsenic before it is housed at their facility.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">We are thinking this might be good for pest management too, during the temporary storage.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Does anyone have thoughts about this idea? If a go, would 4 mil polyethylene be recommended, rather than 2 mil?<u></u><u></u></p>
<p class="MsoNormal">If the Uline product is not appropriate, is there another recommended source?<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
