Cellulose nitrate film is extremely dangerous. It catches fire very easily and once alight is difficult to put out. Fires involving cellulose nitrate burn extremely quickly with a hot, intense flame and the smoke is particularly toxic, containing large quantities of poisonous gases.
Does nitrate film burn faster than paper?
The Narrator explains how dangerous the film nitrate is; he mentions it burns three times faster than paper. It was so dangerous, you couldn’t even bring a film roll on a bus.
How flammable are nitrates?
Nitrate can be very dangerous, mainly because it is highly flammable. Nitrate film burns at a higher temperature than even gasoline. Once ignited a nitrate fire cannot be extinguished, because the combustion process generates its own oxygen. A nitrate fire also generates nitric acid fumes.
How do you extinguish a nitrate film fire?
Nitrate film Nitrate fires burn rapidly and cannot be extinguished, as they are capable of burning even under water. Nitrocellulose is also subject to thermal decomposition and hydrolysis, breaking down over time in the presence of high temperatures and moisture.
How do you handle nitrate film?
Dealing with Nitrate Film
- Keep the ambient temperature as cool as possible and always below 70 degrees F; freezing is recommended.
- Keep the relative humidity between 30-40%
- Do not expose film to sources of heat.
When did they stop using nitrate film?
But there’s physical danger involved in nitrate film. It’s unstable, combustible, and contains a substance that was also used in explosives. Kodak stopped making it in the early 1950s, when it was replaced by more stable film stock.
When was nitrate film banned?
Is 35mm film flammable?
What is nitrate film? Cellulose nitrate was first used as a base for photographic roll film by George Eastman in 1889; it was used for photographic and professional 35mm motion picture film until the 1950s. It is highly flammable and also decomposes with age, becoming toxic.

Why does Old film smell like vinegar?
Vinegar syndrome, officially named acetate film base degradation, is a condition that results from the deterioration of cellulose acetate over the lifespan of a film. As vinegar syndrome progresses, it causes the film to become brittle, shrink, and take on an acidic odor, which smells like vinegar.
What came after nitrate film?
Beginning in the mid-1920s, highly flammable nitrate film was slowly replaced with cellulose acetate film base (cellulose diacetate, cellulose acetate propiarate, cellulose acetate butyrate and cellulose triacetate). It became known as “Safety” film.
