Safe Handling, Storage, and Destruction
of Nitrate-Based Motion Picture Films
This publication will
help you understand
the requirements
to safely handle,
store, transport,
and destroy
Photographic films on cellulose nitrate
base (nitrocellulose) were introduced
by Eastman Kodak Company in 1889.
This film base had excellent physical
properties, but it suffered from poor
chemical stability and high
flammability. In 1948, cellulose
triacetate support was introduced; it
met the performance requirements of
motion picture films and provided
added safety. After 1951, no cellulose
nitrate motion picture film was
manufactured by Kodak.
Association (NFPA), Standard for the
Storage and Handling of Cellulose
Nitrate Motion Picture Film, 1994
Edition (NFPA 40). The NFPA
standards are not laws; however, states
or local authorities, such as a
government agency, local fire
department, or a building/ electrical
inspector may require compliance with
the NFPA standard.
cellulose nitrate-based
films.
IDENTIFICATION
Actual use of cellulose nitrate films
in theaters has virtually ceased.
However, large quantities of cellulose
nitrate film for archival or other
purposes still exist in storage. These
films are typically kept in vaults and
removed for limited projection,
reprinting and restoration on safety
films, or destruction.
Depending on the age of cellulose
nitrate films, the edge of the film may
be marked as nitrate film (“NITRATE
FILM” or “ N ”).
The words “SAFETY FILM” may
appear in the non-image area of a
motion picture film. This usually
indicates that the base is made of a
material, such as cellulose triacetate,
that passes the ISO 435 test for burning
and ignition. However, early motion
picture films marked “SAFETY
FILM” may have been printed on
cellulose nitrate film, which would also
carry the “SAFETY FILM” markings
from print through. If a film cannot be
clearly identified by markings, testing
may be required to determine the
composition of the film base.
This publication will help you
recognize and avoid the hazards
associated with cellulose nitrate motion
picture films. To safely handle, store,
transport, and destroy these films, you
must understand these hazards. The
information in this publication is based
on requirements in the United States;
requirements may differ in other
countries.
The storage and handling
requirements presented are primarily
from the National Fire Protection

Exposure to temperatures in excess of
185°F accelerates decomposition of
these films. While they deteriorate,
nitrate-based films can develop pressure
and heat in the film can, especially when
the can is taped closed. Contained gases
and heat can lead to spontaneous
STORAGE
PROJECTION
Choosing a storage facility for cellulose
nitrate films depends on the amount of
film to be stored.
You need to exercise care when
attempting to project cellulose nitrate
films. Cellulose nitrate motion picture
films may be brittle and shrunken. Do
not attempt to unroll or project a
cellulose nitrate film unless you are
thoroughly familiar with its physical
characteristics. Improper projection can
damage or destroy the film.
Because of the potential fire hazards,
the projection of cellulose nitrate films
is not a common practice. You should
project cellulose nitrate films only in
specially designed enclosures using
projectors with air cooling systems.
(Refer to design specifications in NFPA
40, Chapter 6.) Projection booths in
older theaters were typically constructed
with thick concrete walls, large steel
doors mounted on rolling tracks, and
explosion relief panels. Specialized
projectors with fire prevention rollers
were also used.
Since decomposition is accelerated
with high temperatures, projecting
cellulose nitrate film without air cooling
systems will advance the decomposition
stage. Therefore, do not return film that
was exposed to high temperatures to
your storage vault for long-term storage.
You can reprint your film onto safety
film and then send the cellulose nitrate
film to an authorized facility to be
destroyed.
For short-term storage, you can use
approved film cabinets for storing up to
750 pounds of film (equal to 150 1000-
foot rolls). Use vaults for longer-term
storage of amounts up to 750 pounds.
Always store amounts over 750 pounds
in vaults. Be sure to segregate cellulose
nitrate films from other film storage
areas.
combustion. Therefore, it is
recommended that you store cellulose
nitrate films in painted or tin-plated
metal cans with loose lids. Do not tape
the lids or use tight-fitting lids unless
you are using Molecular Sieves.
Decomposition gases (powerful
oxidizing agents) can also react with
nearby acetate and polyester base films,
so you will need to store cellulose nitrate
films in a separate area. The
decomposition gases can also promote
decomposition of nearby cellulose
nitrate films. If your cellulose nitrate
films need to be stored, but have started
to deteriorate, you must store them in an
area that is separate from other cellulose
nitrate film storage areas.
Store cellulose nitrate films in vaults
in single or double roll containers or in
approved shipping containers. You will
need to examine the entire length of
nitrate films prior to vault storage. If
they are stored with temperature and
humidity controls, you should inspect
nitrate films on a hand rewind machine
annually. Where storage conditions are
not controlled, you should examine
films every six months, or more
frequently in warm climates. Any nitrate
films you find in good condition can be
returned to the storage vault. Any films
that have progressed to the third stage of
decomposition need to be destroyed at
an approved facility.
For extended-term storage (for
preservation of material having
permanent value), store in archival
cabinets or vaults that contain individual
compartments and allow for
decomposition gas venting.
Do not exceed 70°F inside the storage
vault, and maintain the relative humidity
below 50 percent. For long-term storage
requirements, store the film at 35°F at
20- to 30-percent relative humidity.
Refer to the design specifications for
film cabinets and vaults, including
materials of construction, maximum
capacity, venting, and sprinkler
requirements found in NFPA 40,
Chapter 4. You should also check your
local fire code for additional film
storage requirements.
In addition to cool and dry storage,
Molecular Sieves are recommended for
storage of all cellulose nitrate films. You
can promote extended keeping and
preservation of cellulose nitrate films
with the placement of Molecular Sieves
inside the film storage container. These
sieves scavenge and catalytically
decompose the gases that are generated
during the storage of cellulose nitrate
films and retard the degradation
reactions. Molecular Sieves are
available from FPC,

Safe Handling, Storage, and Destruction of Nitrate-Based Motion Picture Films • H-182 (ENG)
following EPA Waste Codes may apply
to cellulose nitrate film:
HAZARDOUS WASTE
STORAGE
WASTE MANAGEMENT
AND DESTRUCTION
Stable cellulose nitrate films
designated for destruction or those that
are in one of the first two stages of
decomposition should be classified as a
hazardous waste using EPA Hazardous
Waste Codes D001 and D003. Cellulose
nitrate films that are in one of the last
three stages of decomposition should be
classified as a hazardous waste using
EPA Hazardous Waste Codes D001,
D003, and D011.
All cellulose nitrate films that are
marked for destruction need to be stored
and transported under water.
Cellulose nitrate films that have reached
the third stage of decomposition, or have
no historical value, need to be destroyed
properly. Since these films decompose
rapidly under certain conditions and are
flammable, it is important that you store
and transport these materials safely.
You will need to place them in a steel
or plastic drum that meets US DOT
specifications, and cover the films with
water. The water must be more than 25
percent by weight of the total weight of
the films. (Water weighs about 8 pounds
per gallon.) Be sure to take into account
the weight of any film reels.
When a cellulose nitrate-based film is
designated for destruction, and is,
therefore, a hazardous waste, RCRA
requirements may apply to your storage
facility. Long-term storage may require a
RCRA permit. When a cellulose nitrate-
based film is determined to be a
WASTE CLASSIFICATION
Once it is determined that a cellulose
nitrate film needs to be destroyed, it is
considered a waste. Under the Resource
Conservation and Recovery Act
(RCRA), all waste cellulose nitrate
films should be classified as hazardous
wastes. Cellulose nitrate film that is
designated for destruction must be
identified as a hazardous waste using all
applicable Environmental Protection
Agency (EPA) Waste Codes. The
hazardous waste, you should send it to an
authorized waste-treatment facility for
proper destruction as soon as possible.
EPA Waste Code
Definition
D001
A material is defined as an ignitable hazardous waste if it
is an oxidizer as defined under USDOT regulations. Nitrate
containing materials are specifically defined as oxidizers
under those provisions.
D003
A material is defined as a reactive hazardous waste if it is
capable of detonation or explosive reaction when subjected
to a strong initiating source or heated under confinement.
Cellulose nitrate films meet this criteria; they will spontane-
ously ignite under elevated temperatures. The rate of
combustion of nitrate films is about fifteen times that of
wood, and the resulting intense fire is virtually impossible to
control or easily extinguish.
D011
A material is defined as a hazardous waste possessing the
characteristic of leachable toxicity for silver if, when
exposed to the Toxicity Characteristic Leaching Procedure
(TCLP), the material leaches > 5 mg/l (ppm) of silver.
Typically photographic films do not leach > 5 mg/l of silver
when subjected to the TCLP. However, during decomposi-
tion, it is likely that more silver may be present during
leaching once the film has reached the third stage of
decomposition. The TCLP can also be performed on a
representative sample of a film to define its characteristics.
