STORAGE/DISPOSAL > Details
Most colleges and universities do not themselves transport hazardous
waste, treat hazardous waste, or operate a hazardous waste disposal
facility. Accordingly, the aspects of the regulations governing these
activities are not addressed in the EVC. More typically, your facility
generates, stores and sends off site for disposal one or more of the
following hazardous wastes:
- Developers (hydroquinone and sodium sulfite)
- Stop baths (acetic acid or similar)
- Fixers (sodium thiosulfate, sodium sulfite, sodium bisulfite,
potassium aluminum, boric acid)
- Hypo eliminators (ammonia and iodine)
- Intensifiers (mercuric chloride, mercuric iodide, potassium
cyanide)
- Reducers (alkali cyanide salts and carbon tetrachloride)
- Toners (gold, selenium, uranium, lead or similar metal)
Often "spent fixer" contains silver at concentrations
that would make the material meet the definition of a hazardous
Waste. Also, unused photochemicals may have to be treated as hazardous
waste due to heavy metal content or the corrosive nature of the
chemicals. Spent fixer can be processed through a silver recovery
unit to allow for this material to be managed as non-hazardous.
Some schools have these units right at the darkroom or photo lab,
while others have the silver recovery units centrally located. Employees
and students shouldn't assume that photochemicals and waste products
can be placed in the waste or poured down the drain without asking
supervisors or environmental, health and safety (EH&S) staff
about their hazardous waste status.
Spent Photographic Chemicals are defined in the new European Waste
Catalogue 2002, classified as:
0901 Wastes from the Photographic Industry
Details of the new European Waste Catalogue 2002 can be seen here.
Hazardous wastes are identified in the EWC with an asterisk (*).
This mean that producers such as Arts/Theatres have a 'Duty of
Care' to identify this waste correctly and dispose of according
to legilsation
Details of the new Hazardous Waste Regulations and general requirements
of waste disposal - Duty of Care - can be viewed here:
