Ventilation-In a chemical mixing area, exhaust

ventilation must be provided The exhaust vent must
draw vapors away from the person mixing the chemicals
and provide a complete air change once every 3 minutes
(20 changes per hour).

Mixing and diluting-Strong acids and strong

oxidizing agents may react violently or produce
explosive products. Toxic gases may be created when

acid is mixed with such chemicals as sulfides, cyanides,
nitrates, and nitrites. Diluting acids with water can
generate considerable heat; acid should always be added
to water, not water to acid. The addition should be done
slowly with constant stirring.

Never smell a chemical directly from the bottle;

instead, hold the bottle at a distance from your nose and
sniff its contents cautiously rather than inhale directly.

Never taste a chemical.

Handle all chemicals cautiously; many can

produce burns or skin irritation.

MATERIAL SAFETY DATA SHEETS
(MSDS)

In addition to the precautions listed previously,

every person in your imaging facility must be
completely familiar with the Material Safety Data
Sheets (MSDS) for each chemical solution used in your
photographic production. The MSDS are provided by

all the manufacturers of hazardous materials. You are
required to have the MSDS for each solution. The
Occupational Safety and Health Administration
(OSHA), as well as your safety officer, performs

periodic safety inspections of your imaging facility.
Every person is responsible for the location and
information contained in the MSDS. MSDS are
generally broken down into 12 sections as follows:

1. Product Information

2. Component Information

3. Precautionary Label Statements

4. Physical Data

5. Fire and Explosion Hazard

6. Reactivity Data

7. Toxicological Properties

8. Protection and Preventive Measures

9. Storage and Disposal

10. First Aid

11. Transportation

12. Preparation Information

It should be noted that separate MSDS may apply

to working solutions and stock solutions or
concentrates. Be certain that the MSDS apply to the
chemical you are in contact with.

ENVIRONMENTAL ISSUES

The Environmental Protection Agency (EPA) has

tightened regulations drastically and they have a

substantial impact on the way imaging facilities conduct
business. All Hazardous Materials (HAZMAT) must be

handled in complete compliance with EPA regulations.
The regulations and tolerances differ from state to state
and base to base. It is important that you comply with
the regulations in your local area

DISPOSING OF HAZARDOUS
MATERIALS

Before you pour photographic chemicals down the

drain or throw material in the dumpster or over the side,

you must be certain that you are not violating any

hazardous material handling or disposal procedures.
You should be completely familiar with the
environmental protection standards and the Ship's
Hazardous Material List for all items that apply to your
command. EPA regulations state that anyone violating
environmental protection regulations can be personally

accountable and fined. When you have ANY doubt, ask
your supervisor before disposing of the material(s).

The MSDS provide information on how to

neutralize and clean up spill containment of
photographic chemicals. When handling and cleaning
up chemical spills, be sure you follow all safety

precautions mentioned previously. It is important that

any chemical spill be cleaned up immediately because
many chemicals are extremely corrosive. These
chemicals may damage or stain the surfaces with which

they come into contact. Consult your local directives on
disposing of materials used to clean up chemical spills

as well as the chemicals themselves.

SILVER RECOVERY

Silver contained in photographic emulsions and

used fixers and bleaches are considered hazardous
