Passage:
Archivists examining early twentieth-century cellulose nitrate film rolls found that reels stored in ventilated steel cabinets at 15°C degraded significantly slower than identical reels sealed in airtight aluminum canisters at 5°C. Chemical analysis revealed that decomposing nitrate film releases autocatalytic acidic vapors. When trapped inside impermeable containers, these vapors exponentially accelerate the breakdown of the remaining film emulsion, regardless of low temperatures. Only when volatile off-gases are continually allowed to dissipate does temperature reduction provide its standard preservation benefits.
Statement:
Based on the passage, it is implied that lowering the storage temperature of cellulose nitrate film is insufficient on its own to prevent accelerated decay if off-gases are trapped.
