The issue with digital storage is the duration of the digital copies.
Even laser discs decay over time, magnetic images decay faster. Tape
images done in the 60s are being retranscribed with serious errors
because of decay of the magnetic poles...

In the Navy we had very large Halon system to combat fires in the main

person sized breathing device that would last you long enough to get
out of that space if Halon was activated. And you can bet we had a lot
of training about it, the alarms, the time you had to get out after
the alarm sounded before it was deployed etc.
In conjunction with the idea of losing documents, we should as a
society get better at scanning these things. It is so much easier to
have multiple diverse digital copies of these than the physical paper.
Hell the banking industry got out of the paper check stuff 20 years
ago. Have you looked at old documents scanned from original from
places like Ancestry.com or Family.searc.org? They have links to a lot
of governmental document sources, for instance I could see scans of
the military muster reports for family members in the revolutionary
war or from the state records of pension payments to civil war
veterans. Mind boggling that we can now see scans of those original
documents.
Thank you,

I visited one of those once. Before going in we had to have a
training session about the alarms and the controls. Not sure if we
were supposed to do something other than leave if the alarm went off.
Maybe there was a delay to allow us to exit before releasing the gas.
It was a serious deal.

In my former years, data centers often had halon systems which would
displace air in the entire data center. They were phased out because
no air is just as bad for humans as it is for fires.

Wow, I am sure there are lots of irreplaceable documents. So
if you were to

I guess structural engineering needs to presume all the racks
are full of
water.

Here in the Chicago suburbs, a 250k sqft document storage
warehouse just
burned down. It took them a week to put out the fire. 30' Racks
stacked with banker boxes, when the building sprinklers hit
it, the
paper got waterlogged and got too heavy for the racks to
support and
came down, taking roof supports and building sprinkler system
down with
them. Once the roof was opened up, the fire got lots of air,
and just
started raging. With the roof gone, nothing was holding up
the precast
walls, etc.etc. Basically there's no more building left.
So what kind of paper documents are stored in warehouses like
this? Bank
Documents? Law office contracts? The Panama Papers? I'm
just curious
what the market is for industrial scale paper storage like
this. I see
a lot of storage places like this around the suburbs. Iron
Mountain has
a couple big facilities. I'm guessing you are responsible for
your own
redundant copies at multiple storage warehouses? Also seems
like if
there are just boxes of papers stacked on a shelf, there's
really no
security.
