[Nhcoll-l] risks to study skins from thermal change, and time spent out of cabinetry

[Haff, Tonya (NCMI, Crace)]

Hello everyone,

I have a few questions regarding handling specimens for digitisation. We are currently planning a new building (sorry I know I've said that a few times now!), and are planning to have the skin and insect vaults kept at 16C (to reduce pest risk). Specimens will be kept in museum grade cabinetry inside the vaults. The curation spaces will be at about 22C.

I have heard vague concerns that the temperature differential between the vaults and the curation space could lead to condensation on the specimens. I was wondering if any of you could speak to whether or not this is something we should worry about? Please note we are in a very dry climate.

In part because of the concern about temperature differentials, and in part to reduce the work of putting specimens away at the end of each day while they are being digitised, it has been asked if specimens could be left out  in the digitisation space, overnight or for a few days. This is a 'clean' zone (no food, high building hygiene standards, no specimens  that have not been preventatively frozen for pests). One option would be to keep specimens out of the vaults, but in sealed cabinetry overnight, and another would simply to be leave them in a secured room on the digitisation benches.

I do have thoughts about this, but am trying to be neutral, and I would love to hear if any of you have opinions or experience these topics.  If you have other thoughts as to how to increase the digitisation team's efficiency while reducing risk to specimens I would also love to hear it.

Thanks so much!

Cheers,

Tonya
