The recommendation for Acetate film with VS is to keep it well ventilated or to use the special "Sieves" to keep it away from the gas. Nitrate has so many other requirments listed that is it easy to miss the ventilation requirements.

Unexposed film is shipped in sealed containers to protect the emulsion from contamination. Sealed World war II film has been sealed and soaking in its own out-gassing for sixty Five years (at Least) so if there has been any decomposition it is probably already in the sweating dynamite stage of its life (http://en.wikipedia.org/wiki/Dynamite)
