humans. There may be no safe level of exposure to a
carcinogen, so all contact should be reduced to the lowest
possible level.
WAYS OF REDUCING EXPOSURE
* Where possible, enclose operations and use local exhaust
ventilation at the site of chemical release. If local exhaust
ventilation or enclosure is not used, respirators should be
worn.
* A regulated, marked area should be established where 1-Amino-
2-methylanthraquinone is handled, used, or stored.
* Wear protective work clothing.
* Wash thoroughly immediately after exposure to 1-Amino-2-
methylanthraquinone and at the end of the workshift.
* Post hazard and warning information in the work area. In
addition, as part of an ongoing education and training effort,
communicate all information on the health and safety hazards
of 1-Amino-2-methylanthraquinone to potentially exposed
workers.
This Fact Sheet is a summary source of information of all potential
and most severe health hazards that may result from exposure.
Duration of exposure, concentration of the substance and other
factors will affect your susceptibility to any of the potential
effects described below.
------------------------------------------
HEALTH HAZARD INFORMATION
Acute Health Effects
The following acute (short term) health effects may occur
immediately or shortly after exposure to 1-Amino-2-
methylanthraquinone:
* Contact may irritate the eyes and skin.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to 1-Amino-2-methylanthraquinone and can last
for months or years:
Cancer Hazard
* 1-Amino-2-methylanthraquinone is a PROBABLE CARCINOGEN in
humans. There is some evidence that it causes liver and kidney
cancer in animals.
* Many scientists believe there is no safe level of exposure to
a carcinogen. Such substances may also have the potential for
causing reproductive damage in humans.
Reproductive Hazard
* According to the information presently available to the New
Jersey Department of Health, 1-Amino-2-methylanthraquinone has
not been tested for its ability to adversely affect
reproduction.
Other Long Term Effects
* 1-Amino-2-methylanthraquinone has not been tested for other
chronic (long term) health effects.
MEDICAL TESTING
There is no special test for this chemical. However, if illness
occurs or over exposure is suspected, medical attention is
recommended.
Any evaluation should include a careful history of past and present
symptoms with an exam. Medical tests that look for damage already
done are not a substitute for controlling exposure.
Request copies of your medical testing. You have a legal right to
this information under OSHA 1910.20.
WORKPLACE CONTROLS AND PRACTICES
Unless a less toxic chemical can be substituted for a hazardous
substance, ENGINEERING CONTROLS are the most effective way of
reducing exposure. The best protection is to enclose operations
and/or provide local exhaust ventilation at the site of chemical
release. Isolating operations can also reduce exposure. Using
respirators or protective equipment is less effective than the
controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider: (1)
how hazardous the substance is, (2) how much of the substance is
released into the workplace and (3) whether harmful skin or eye
contact could occur. Special controls should be in place for highly
toxic chemicals or when significant skin, eye, or breathing
exposures are possible.
In addition, the following control is recommended:
* Where possible, transfer 1-Amino-2-methylanthraquinone from
drums or other storage containers to process containers.
Good WORK PRACTICES can help to reduce hazardous exposures. The
following work practices are recommended:
* Workers whose clothing has been contaminated by 1-Amino-2-
methylanthraquinone should change into clean clothing
promptly.
* Do not take contaminated work clothes home. Family members
could be exposed.
* Contaminated work clothes should be laundered by individuals
who have been informed of the hazards of exposure to 1-Amino-
2-methylanthraquinone.
* On skin contact with 1-Amino-2-methylanthraquinone,
immediately wash or shower to remove the chemical. At the end
of the workshift, wash any areas of the body that may have
contacted 1-Amino-2-methylanthraquinone, whether or not known
skin contact has occurred.
* Do not eat, smoke, or drink where 1-Amino-2-
methylanthraquinone is handled, processed, or stored, since
the chemical can be swallowed. Wash hands carefully before
eating or smoking.
* Use a vacuum or a wet method to reduce dust during clean up.
DO NOT DRY SWEEP.
* When vacuuming, a high efficiency particulate absolute (HEPA)
filter should be used, not a standard shop vacuum.
PERSONAL PROTECTIVE EQUIPMENT
WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT.
However, for some jobs (such as outside work, confined space entry,
jobs done only once in a while, or jobs done while workplace
controls are being installed), personal protective equipment may be
appropriate.
The following recommendations are only guidelines and may not apply
to every situation.
Clothing
* Avoid skin contact with 1-Amino-2-methylanthraquinone. Wear
protective gloves and clothing. Safety equipment
suppliers/manufacturers can provide recommendations on the
most protective glove/clothing material for your operation.
* All protective clothing (suits, gloves, footwear, headgear)
should be clean, available each day, and put on before work.
Eye Protection
* Eye protection is included in the recommended respiratory
protection.
Respiratory Protection
IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should
only be used if the employer has a written program that takes into
account workplace conditions, requirements for worker training,
respirator fit testing and medical exams, as described in OSHA
1910.134.
* Engineering controls must be effective to ensure that exposure
to 1-Amino-2-methylanthraquinone does not occur.
* At any exposure level, use a MSHA/NIOSH approved supplied air
respirator with a full facepiece operated in the positive
pressure mode or with a full facepiece, hood, or helmet in the
continuous flow mode, or use a MSHA/NIOSH approved self
contained breathing apparatus with a full facepiece operated
in pressure demand or other positive pressure mode.

ECOLOGICAL INFORMATION
1-Amino-2-methylanthraquinone is a solid chemical used as an
intermediate in the production of anthraquinone vat dyes. It may
enter the environment from industrial discharges or spills.
ACUTE (SHORT-TERM) ECOLOGICAL EFFECTS
Acute toxic effects may include the death of animals, birds, or
fish, and death or low growth rate in plants. Acute effects are
seen two to four days after animals or plants come in contact with
a toxic chemical substance.
1-Amino-2-methylanthraquinone has moderate acute toxicity to
aquatic life and high acute toxicity to birds. Insufficient data
are available to evaluate or predict the short-term effects of
1-amino-2-methylanthraquinone to plants or land animals.
CHRONIC (LONG-TERM) ECOLOGICAL EFFECTS
Chronic toxic effects may include shortened lifespan, reproductive
problems, lower fertility, and changes in appearance or behavior.
Chronic effects can be seen long after first exposure(s) to a toxic
chemical.
1-Amino-2-methylanthraquinone has moderate chronic toxicity to
aquatic life. Insufficient data are available to evaluate or
predict the long-term effects of 1-amino-2-methylanthraquinone to
plants, birds, or land animals.
WATER SOLUBILITY
1-Amino-2-methylanthraquinone is moderately soluble in water.
Concentrations of between 1 to 1,000 milligrams will mix with a
liter of water.
DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT
1-Amino-2-methylanthraquinone is highly persistent in water, with
a half-life greater than 200 days. The half-life of a pollutant is
the amount of time it takes for one-half of the chemical to be
degraded. About 91% of 1-amino-2-methyl-anthraquinone will
eventually end up in water; the rest will be divided about equally
between terrestrial soils and aquatic sediments.
BIOACCUMULATION IN AQUATIC ORGANISMS
Some substances increase in concentration, or bioaccumulate, in
living organisms as they breathe contaminated air, drink
contaminated water, or eat contaminated food. These chemicals can
become concentrated in the tissues and internal organs of animals
and humans.
The concentration of 1-amino-2-methylanthraquinone found in fish
tissues is expected to be somewhat higher than the average
concentration of 1-amino-2-methylanthraquinone in the water from
which the fish was taken.
