INTRODUCTION
The Occupational Safety and
Health Administration (OSHA)
presents a framework of federal
regulations that set chemical
exposure standards for the
workplace environment. These
standards outline allowable limits
that employees may be safely
exposed to during the work day.
Effective ventilation systems are an
important tool that will help
minimize employee exposure to

temperature and atmospheric
pressure (STP, 22.5°C, and 760 mm
Hg). A gas is in the gaseous state at
STP (examples: nitrogen, carbon
dioxide, sulfur dioxide). A vapor is a
gas from a substance that at STP is a
liquid (example, acetic acid).
Particulates: There are several
forms of particulate matter that can
be airborne. These include:
In a work environment where
chemicals are used, an individual
may potentially be exposed in three
ways:
Dose Response: All chemicals are
toxic if taken into the body by the
right route of exposure and at a high
enough dose. As the dose increases,
there is a corresponding effect or
response.
Chemicals that requirelarge doses
or exposure concentrations to
produce an adverse effect have a
low toxicity, while chemicals that
require smaller doses to produce an
adverse effect are considered more
toxic. For example, acetic acid is
irritating to the eyes and upper
respiratory system at low
concentrations, about 10 ppm.
Isopropyl alcohol is not irritating to
the eyes until concentrations reach
over 400 ppm. Based on this
comparison, acetic acid causes an
irritation at much lower
• inhalation
• skin and eye contact
• ingestion
Inhalation is the most common
route of exposure for airborne
particulates, gases, and vapors.
Inhalation exposures are important
because many chemicals that enter
the lungs can pass directly into the
blood stream and be transported to
other areas of the body.
• dust
• fumes
• smoke
• mists
Dust results from the application
of energy to matter, by grinding,
sifting pouring solids, paper cutting,
etc. Dust particles have to be small
enough and light enough to be
airborne.
Fumes are generated by the
condensation of particles in the
vapor state from heated metals.
Fumes are typically smaller than
dust, more soluble, and are more
physiologically active. Fumes are
not generated during normal
photographic processing
Skin contact can also be a
significant source of exposure which
can lead to adverse health effects.
Some chemicals can be absorbed
into the body through the skin while
others may cause irritation or rashes
(dermatitis). In addition, some
chemicals are potential eye irritants.
Ingestion is not considered to be a
significant problem in the
workplace. Inadvertent ingestion of
chemicals may occur if food or
beverages are consumed in chemical
handling areas or if good personal
hygiene practices are not followed,
i.e., washing hands before eating,
drinking, smoking, etc.

operations.
Smoke results from incomplete
combustion and is made up of
extremely fine particles, even
smaller than fumes. Smoke is
extremely complex chemically,
containing thousands of chemical
substances. Unless something is
burning, smoke is not generated
during photographic processing
operations.
Mists result from the dispersion
of fine droplets by aerosolization of
any liquid (spray cans, nitrogen
agitation of tanks, electroplating).
Mists can be formed during the
mixing, recirculation or pouring of
liquids. Mist can also be generated
from foam on the surface of a liquid.
The air within buildings usually
contains a variety of air
contaminants. These contaminants
can originate from outside sources
(car/truck exhaust) or emissions
from inside sources (office
equipment, furnishings, carpet,
people, kitchens, janitorial
activities).
Air contaminants: are chemicals
that may be present in the air that
could be inhaled and may produce
adverse effects. These effects can be
divided into two classes:

of the liquid are released into the air.
The composition of a mist is usually
the same as the liquid from which it

concentration that is representative
of a worker’s exposure that should
not be exceeded.
Action Level (AL): For the
comprehensive standards
established by OSHA, an Action

the concentration at which you may
have to address certain compliance
requirements such as employee
monitoring, training, or medical
surveillance.

conditions of the equipment. Some
photographic processing solutions
release small amounts of vapors
such as acetic acid and benzyl
alcohol or gases such as ammonia, or
sulfur dioxide. High-temperature
processing and nitrogen-burst
agitation of tank solutions may
increase the release of chemicals
into the air and generate mists from
the photographic processing
solutions. Depending on the
concentration in the air, these
chemicals could be irritating to the
eyes and respiratory tract, or create
odors. Although odor does not
always indicate safe versus unsafe
conditions, strong odors or the
presence of eye and/or respiratory
irritation can indicate that there is
not sufficient general dilution
ventilation or that the local exhaust
systems may not be capturing the air
contaminants effectively at their

New canister samplers allow for the
sample to be drawn in over a much
longer period of time, if desired.
This technique is most useful for
volatile organic hydrocarbons.
Engineering controls that have
proven to be effective in minimizing
airborne levels of photographic
processing chemicals include:
• Good design and layout for
process flow and ergonomic
considerations
Many different direct reading
instruments are available for air
sampling measurements. Some of
these can be very specific to a
chemical (e.g., sulfur dioxide
analyzers) while others are

analyzer with photoionization [PID]
or flame ionization [FID] detectors).
Calibrate all instruments before and
after making any measurements.
• Using dilution and local exhaust
ventilation
• Providing covers for processing
equipment tanks and chemical
storage tanks
Proper ventilation is important to
assure a safe and comfortable indoor
environment for photographic
processing areas. Several common
potential indoor air contaminants
can be associated with photographic
processing. These include: acetic
acid, sulfur dioxide, and ammonia.
These chemicals may be eye and
respiratory tract irritants depending
on their airborne concentrations.
Exposure guidelines and standards
for these chemicals have been
established to prevent significant
eye or respiratory tract irritation in
most workers. Significant eye or
respiratory tract irritation during
normal photographic processing or
maintenance operations may
indicate elevated levels of these
materials and the need for better
control.
Samples with Subsequent
Laboratory Analysis
There are many air sampling
techniques that rely on collecting a
known volume of air followed by
laboratory analysis.
GOOD FACILITY DESIGN
The proper location and layout of
photographic processing operations
is an important element in designing
a safe and healthy workplace.
General ventilation systems have
the potential to recirculate a
significant percentage of the air
returning from the photographic
processing areas. If the general
ventilation system also supplies
non-photographic processing work
areas, it is possible that the
photographic processing odors may
also impact these areas.
VENTILATION
Passive diffusion badges are easy
to use and excellent for measuring
many volatile organic compounds.
This method is most useful for
measuring (quantifying) known
airborne contaminants. Although
passive badges are commonly
employed for measuring full shift
average exposures, they also can be
useful for short-term exposure
measurements.

exposure during automated

When using dilution ventilation,
airborne contaminants are not
captured at the source. Instead, the
contaminated air is turned over and
replaced quickly enough to
levels but is not considered local
exhaust ventilation. A local exhaust
system may be more expensive to
install than a general dilution
ventilation system, but requires less
air (and energy) to effectively
control the airborne contaminants.
When designing local exhaust
systems, the objective is to capture
contaminants close to the source and
draw the contaminated air stream
away from the air you breathe.
Avoid placing workstations
DILUTION VENTILATION
Dilution or general ventilation is
simply bringing in and distributing
enough fresh, uncontaminated air
(preferably outdoor air) to dilute the
indoor air contaminants to an
acceptable level.
Minimum recommendations for
general ventilation for buildings and
processes are provided by the
American Society of Heating,
Refrigeration and Air Conditioning
Engineers (ASHRAE).

related odors. To be most effective,
make sure you properly position the
supply air inlets and return air
outlets for good mixing/dilution of
the room air. Their placement must
minimize the potential for “short-
circuiting” or direct flow of supply
air to return with minimum room air
mixing (Figure 2). For a large room,
you may need supply air inlets and
return air outlets throughout the
room. Do not position the inlet and
outlets too close together.

photographic processing operations
are a combination of both local
exhaust and dilution ventilation
(Figure 3). Fresh dilution air1 should
be supplied to the darkroom at a rate
of 150 cfm per machine. If a machine
extends through a barrier into
another room, supply fresh dilution
air to both rooms. Depending on the
process chemistry, you may need
local exhaust at uncovered stabilizer
tanks or at the bleach fix tanks at a
rate of 170 cfm per machine
If solution tanks are enclosed or covered, the fresh air supply rate may be
reduced to 90 cfm and the exhaust rate to 100 cfm per machine (Figure 5).
(Figure 4). In many cases, exhaust is
also provided at the dryer section to
help control heat and humidity in
the room. An exhaust rate slightly
greater than the supply rate results
in a negative room air pressure
which reduces the potential for air
contaminants and odors for
escaping from the photographic
processing area to any adjacent
areas.

Covers on photographic processing
equipment and chemical storage
tanks can effectively minimize the
amount of gases, vapors or mists
that may enter the work area. In
addition, covers also reduce the
potential for contamination of the
processing solutions. Covers should
be fabricated from durable, non-
reactive materials and should cover
as much of the open surface of the
tank as possible. In many cases,
effective tank covers combined with
good general room ventilation, and
proper operation and maintenance
may be all that is needed to control
odors and airborne exposure to
photographic processing chemicals.
In situations where local exhaust is
needed for a covered tank, 25 - 30
cubic feet per minute (cfm) per
square foot of tank area is adequate.
The level of airborne contamination
generated from photographic
processing solutions can be affected
by how the processing equipment is
operated. It is important to follow
the manufacturer’s recommended
operating procedures for operating
temperature, the agitation of
processing solutions, and
processing speeds.
In addition, draining and flushing
processing equipment tanks with
cold water prior to rack removal or
maintenance operations can also be
effective at controlling short-term
exposures to processing solutions.
The health, comfort, and
efficiency of personnel, as well as the
proper conditions for processing,

photographic materials depends on
a suitable indoor air environment.
