EPA Waste Code
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.
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.
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.
