<p class="MsoNormal"><span style="color:#1F497D">Majken,</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">I certainly look forward to visiting your new facility when it is completed. Who knows, may be you’ll be hosting a SPNHC Annual Meeting to show it off. Hint! Hint!</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">As far as dealing with the proper preservation of specimens and the protection of users when handling these specimens, my first approach/response would be
<u>procedures</u>.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">Certainly, in both situations (contaminated study skins and formaldehyde-preserved samples) appropriate personal protective equipment (PPE) is a must. Working with this type of material under fume hoods would
also be important, especially for the formalin stuff. It is not always convenient but if your facility is designed with these requirements in mind, then you can make it work fairly well.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">As far as transferring samples from formaldehyde into ethanol, you will need a lab with lots of air exchange and a good fume hood. Unfortunately, not all material preserved in formaldehyde should be transferred
in ethanol. Groups like some planktonic cnidarians may disappear (dissolve) in ethanol while others like copepods and chaetognaths will become opaque, presenting observation of internal structures necessary for species and live stage determination. Therefore,
if you decide to keep these in formaldehyde, the only good procedure for users is to work with the whole sample under a fume hood (with appropriate PPE) and with air-extracting trunks for microscope sorting and observations.
</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">I am sure others will have good recommendations to suggest.</span></p>
<p class="MsoNormal"><span style="color:#1F497D"> </span></p>
<p class="MsoNormal"><span style="color:#1F497D">Keep us informed and best success in your planning and preparation.</span></p>

<p class="MsoNormal"><span lang="EN-US">First question </span><span lang="EN-US" style="font-family:Wingdings">J</span><span lang="EN-US"></span></p>
<p class="MsoNormal"><span lang="EN-US">The Copenhagen collections are old and therefore a great deal of the bird- and mammal skins is treated with arsenic. Furthermore we still have smaller parts of the wet collections still stored in a formalin solution (the
latter is to be transferred to alcohol, when finding the resources).</span></p>
<p class="MsoNormal"><span lang="EN-US">On one hand, we wish to keep the collections active, e.g. having scientist and students studying the collections, sending out (and receiving) loans etc. - on the other hand we wish to protect the people handling the specimens.</span></p>
<p class="MsoNormal"><span lang="EN-US">How do you deal with that dilemma in your institution?</span></p>
