Common Name: 2,4-Diaminoanisole
CAS Number: 615-05-4
DOT Number: None
Date: May, 1989
-----------------------------------------
HAZARD SUMMARY
* 2,4-Diaminoanisole can affect you when breathed in and by
passing through your skin.
* 2,4-Diaminoanisole should be handled as a CARCINOGEN WITH
EXTREME CAUTION.
* Repeated exposure may damage the liver and thyroid. Goiter may
develop with higher doses.
* Skin or eye contact can cause irritation.
* High exposures can cause tremors (a nervous system effect),
weakness, difficulty breathing, and diarrhea.
* Closely related chemicals (Phenylenediamines) can cause skin
and lung allergy. It is not known if 2,4-Diaminoanisole has
these effects.
IDENTIFICATION
2,4-Diaminoanisole is a colorless, needle shaped substance. It is
used in hair and fur dye formulations.
REASON FOR CITATION
* 2,4-Diaminoanisole is on the Hazardous Substance List because
it is cited by DEP, NIOSH and EPA.
* Definitions are attached.
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
* Exposure to hazardous substances should be routinely
evaluated. This may include collecting personal and area air
samples. You can obtain copies of sampling results from your
employer. You have a legal right to this information under
OSHA 1910.20.
* If you think you are experiencing any work related health
problems, see a doctor trained to recognize occupational
diseases. Take this Fact Sheet with you.
WORKPLACE EXPOSURE LIMITS
No occupational exposure limits have been established for 2,4-
Diaminoanisole. This does not mean that this substance is not
harmful. Safe work practices should always be followed.
* It should be recognized that 2,4-Diaminoanisole can be
absorbed through your skin, thereby increasing your exposure.
* NIOSH recommends that 2,4-Diaminoanisole be handled as if it
was a human carcinogen. Exposure should be reduced to the
lowest feasible level.
* 2,4-Diaminoanisole may be a CARCINOGEN in 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.
* Wear protective work clothing.
* Wash thoroughly immediately after exposure to 2,4-
Diaminoanisole 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 2,4-Diaminoanisole 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 2,4-Diaminoanisole:
* High exposures can cause weakness, tremors (a nervous system
effect), increased saliva, breathing difficulty, and diarrhea.
* Skin or eye contact can cause irritation.
* Some related chemicals interfere with the ability of red blood
cells to carry oxygen to body organs (methemoglobinemia). If
severe, blue lips and skin may occur. The extent of this
effect with 2,4-Diaminoanisole is unknown.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to 2,4-Diaminoanisole and can last for months
or years:
Cancer Hazard
* While 2,4-Diaminoanisole has not yet been identified as a
carcinogen, it should be HANDLED WITH CAUTION since a related
chemical, 2,4-Diaminoanisole Sulfate, is a carcinogen in
animals.
Reproductive Hazard
* While 2,4-Diaminoanisole has not been identified as a
reproductive hazard, it should be HANDLED WITH CAUTION since
there is limited evidence that 2,4-Diaminoanisole Sulfate, a
related chemical, is a teratogen.
Other Long Term Effects
* Repeated exposures may affect the liver, thyroid and thyroid
function of the pituitary gland. Goiter may develop in some
cases with higher doses.
* Some related chemicals (Phenylenediamines) can cause skin and
lung allergy. Once allergy develops, even low future exposure
can trigger symptoms of redness, itching (skin) or cough,
wheezing (lung). It is unknown if 2,4-Diaminoanisole also has
these effects.
MEDICAL
Medical Testing
If symptoms develop or overexposure is suspected, the following may
be useful:
* Thyroid exam; test of thyroid function.
* Evaluation by a qualified allergist, including careful
exposure history and special testing, may help diagnose skin
allergy.
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, automatically transfer 2,4-Diaminoanisole 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 2,4-
Diaminoanisole 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 2,4-
Diaminoanisole.
* On skin contact with 2,4-Diaminoanisole, immediately wash or
shower to remove the chemical. At the end of the workshift,
wash any areas of the body that may have contacted 2,4-
Diaminoanisole, whether or not known skin contact has
occurred.
* Do not eat, smoke, or drink where 2,4-Diaminoanisole 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 2,4-Diaminoanisole. 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 2,4-Diaminoanisole 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
2,4-Diaminoanisole is a solid chemical, which is the methyl ether
of compounds used in photographic developers and dyes. It may
enter the environment from industrial or municipal 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.
2,4-Diaminoanisole has slight acute toxicity to aquatic life.
Insufficient data are available to evaluate or predict the short-
term effects of 2,4-Diaminoanisole to plants, birds, 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.
2,4-Diaminoanisole has slight chronic toxicity to aquatic life.
Insufficient data are available to evaluate or predict the long-
term effects of 2,4-Diaminoanisole to plants, birds, or land
animals.
WATER SOLUBILITY
2,4-Diaminoanisole is highly soluble in water. Concentrations of
1,000 milligrams and more will mix with a liter of water.
DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT
2,4-Diaminoanisole is moderately persistent in water, with a half-
life of between 20 to 200 days. The half-life of a pollutant is
the amount of time it takes for one-half of the chemical to be
degraded. Virtually 100% of 2,4-diaminoanisole will end up in the
water.
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 2,4-Diaminoanisole found in fish tissues is
expected to be about the same as the average concentration of 2,4-
Diaminoanisole in the water from which the fish was taken.
