[Nhcoll-l] Shelf depth for EtOH jar collections

Wed Feb 15 13:51:38 EST 2023

I believe that one of Paul's messages inadvertently did not go to nhcoll-l,
so I have reposted it below, along with my response.

The reason that we did not include a tray option in *Best Practices in the
Preservation and Management of Fluid-Preserved Biological Collections *is
because the use of trays on shelving is so rarely allowed. As Andy pointed
out, trays impede the flow of water from overhead sprinkler systems.

It is important to keep in mind that international fire codes do not
address the storage of fluid-preserved specimens. Code regulations are
focussed on the storage of bulk alcohol (usually full-strength and in large
containers) and the storage of retail liquor (which is rarely more than 40%
ETOH). No matter what fire code your local official use, there will be
interpretations made to accommodate fluid-preserved specimens. The
interpretations vary widely. For example, when the fluid collection
facility was built at the University of Kansas, we were not allowed to
store alcohol below grade (below ground level) because alcohol vapors are
heavier than air and would accumulate below ground. However, below grade
storage has been allowed in other places in the US, using the same fire
code, interpreted by different officials. In the case of KU, we were
fortunate that one of the architects became very interested in the project
and helped us negotiate many of the objections made by our local fire
marshall (although not all--we were still forced to go with 100% air
make-up which was both overkill and a huge maintenance headache). So, the
fact that one place allows trays does not mean others will, and we could
find very few collections anywhere in the world that were allowed to use
them (there are collections using metal, wood, or cardboard trays that
have thus
far escaped close inspection by fire officials). It is not that we did not
like Paul's idea, it is that it is not practical in most places. But if you
can talk your local fire marshall into allowing it, the trays are very
useful.

*Here is Paul's earlier post:*

To John’s first point – a metal tray system solves all the problems of
shelf depth. You don’t reach in to pull up and look at containers behind
the first row, you pull the tray out instead. As long as you only have a
maximum of two rows of containers, you can eyeball everything instantly for
condition, fully addressing the point he makes about planning for
maintenance cycles.

Sadly, the recent Fluid-preserved Biological Collections book did not
mention these systems at all, despite our design and its advantages having
been published by SPNHC.

As for collection density, fire-rated space in existing buildings is
expensive to create and rarely possible to expand. Like it or not, to stay
in code you often have to find ways to fit more into an existing space. We
did that, in the form of a cheap and practicable upgrade to existing
shelving of any kind.
