Acetate may damage nearby materials if in an advanced state of deterioration; film displaying signs of deterioration should be separated from other collections and evaluated for conservation, digitization, or discard.

Role of spiro-OMeTAD in performance deterioration of perovskite solar cells at high temperature and reuse of the perovskite films to avoid Pb-waste†. This is a problem because the high fire risk from cellulose nitrate film increases as it ages. The following signs of deterioration may be present: amber, brown An increase in the microbial population and in the pH was observed over the storage period as result of pork deterioration.
As acetate film decays, it shrinks, loses flexibility, curls, and wraps. Safety motion picture film (so called because it is not flammable like nitrate base film) was almost always made of cellulose acetate plastic. A key issue in preserving this type of film is controlling the form of decay known as "vinegar syndrome."

Acetate: Cellulose acetate film is susceptible to vinegar syndrome, which causes the film base to shrink and the gelatin emulsion to pull up in folds. A strong vinegar odor is a telltale symptom in later stages of deterioration.
In the cross-section of the films, the grains are surrounded by several microholes and cracks, which can act as “channels” to allow the moisture and oxygen to pass through and lead to deterioration of the films. all 3/joey eppard/the dear hunter/weerd science videos are uploaded with permission; if you enjoy them please support the bands and their forward thinking Acetate film is at a moderately high risk level and should be monitored closely for signs of deterioration.
