Mass digitisation of degrading cellulose acetate collections

The State Library of NSW is undertaking a mass digitisation program
and one of the collections to be digitised contains a large number
(over 200,000) of cellulose acetate negatives, many with mild to
medium vinegar syndrome.  The collection is now in frozen storage.
I would like to hear from others with experience in digitising
degrading cellulose acetate material, in particular about what
equipment you chose for digitisation, methods to overcome health
concerns from the off-gassing negatives, whether the digitisation
was done in-house or through external vendors, and any other advice
would be appreciated.
