[Nhcoll-l] [EXTERN] The rate of exchange of air volumes in fluid specimen room

[Dirk Neumann]

Hi Joosep,

please have a look at the article of Peter Bartsch regarding the new fluid collections for the reconstructed east wing at the MfN in Berlin; please also have a look how the ASHRAE corridors are interpreted by different authors, especially from the Mediterranean.

We have to assume we have to deal with an increase of hot and humid days. By no means indoor climates be handled via HVAC systems. Instead, HVAC systems will start to oscillate fast and pulsed around set points and thus can cause frequent micro-damage, especially to (historic) jars

The Website of Tim Padfield also is a immensely valuable resource: https://www.padfield.org/tim/cfys/index.html

For emergencies (spillage, accidents), you need to consider ethanol fume detectors near the floor to detect potentially combustible ethanol atmospheres soon after they emerge. This should be combined with stringent avoidance of any potential ignition sources within the storage room (power plugs), no working spaces, etc.

There is guidance and reference in our book, which has an own section on fire prevention and detection (5.4): https://archetype.co.uk/our-titles/preservation-and-management-of-fluid-preserved-biological-collections/?id=440

Hope this helps
Dirk

Dear all,
We are building a new fluid specimen room in our new museum and would like to make it as safe as possible (according to latest knowledge). Project managers would like to know then what should be the rate of exchange of air volumes in fluid specimen room? In the normal situation and then in the accident situation?

Sincerely,
Joosep Sarapuu
