Common Name: Aldrin
CAS Number: 309-00-2
DOT Number: NA 2761
Date: November, 1988
-----------------------------------------
HAZARD SUMMARY
* Aldrin can affect you when breathed in and by passing through
your skin.
* Aldrin should be handled as a CARCINOGEN and a teratogen
HANDLE WITH EXTREME CAUTION. It may also decrease fertility in
males and females.
* High exposures may cause headaches, dizziness, nausea and
vomiting, muscle jerks, severe seizures, and death.
* Aldrin may also cause a skin allergy.
* Exposure may damage the liver.
IDENTIFICATION
Aldrin is a colorless, white, or tan to dark brown, crystalline
(sand like) material, with a mild, chemical odor. It is an
organochlorine insecticide.
REASON FOR CITATION
* Aldrin is on the Hazardous Substance List because it is
regulated by OSHA and cited by ACGIH, NIOSH, DEP, DOT and EPA.
* This chemical is on the Special Health Hazard Substance List
because it is a CARCINOGEN.
* 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
OSHA: The legal airborne permissible exposure limit (PEL) is
0.25 mg/m3 averaged over an 8 hour workshift.
NIOSH: Recommends the lowest reliably detectable level (0.15
mg/m3 averaged over an 8 hour workshift by NIOSH
validated method).
ACGIH: The recommended airborne exposure limit is 0.25 mg/m3
averaged over an 8 hour workshift.
* The above exposure limits are for air levels only. When skin
contact also occurs, you may be overexposed, even though air
levels are less than the limits listed above.
* Aldrin 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 Aldrin 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 Aldrin 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 Aldrin:
* High exposures may cause headaches, dizziness, nausea and
vomiting, muscle jerks, severe seizures and death.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to Aldrin and can last for months or years:
Cancer Hazard
* Aldrin may be a CARCINOGEN in humans since it has been shown
to cause liver 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
* Aldrin may be a TERATOGEN in humans since it has been shown to
be a teratogen in animals.
* Aldrin may decrease fertility in males and females.
Other Long Term Effects
* Aldrin may cause a skin allergy. If an allergy develops, very
low future exposures can cause itching and a skin rash.
* Exposure may damage the liver.
MEDICAL
Medical Testing
If symptoms develop or overexposure is suspected, the following may
be useful:
* EEG (a brain activity wave test to look for seizure).
* Liver function tests.
* 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 controls are recommended:
* Where possible, automatically transfer Aldrin from drums or
other storage containers to process containers.
* Specific engineering controls are recommended for this
chemical by NIOSH. Refer to the NIOSH criteria document:
Occupational Exposure During the Manufacture and Formulation
of Pesticides #78 174.
Good WORK PRACTICES can help to reduce hazardous exposures. The
following work practices are recommended:
* Workers whose clothing has been contaminated by Aldrin 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 Aldrin.
* If there is the possibility of skin exposure, emergency shower
facilities should be provided.
* On skin contact with Aldrin, immediately wash or shower to
remove the chemical. At the end of the workshift, wash any
areas of the body that may have contacted Aldrin, whether or
not known skin contact has occurred.
* Do not eat, smoke, or drink where Aldrin is handled,
processed, or stored, since the chemical can be swallowed.
Wash hands carefully before eating or smoking.
* 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 Aldrin. 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 Aldrin 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
Aldrin is a solid which is used as an insecticide primarily to
control termites, and most likely enters the environment from
industrial discharges, urban runoff, 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.
Aldrin has high acute toxicity to aquatic life and to birds. It
has caused injuries of several kinds to both agricultural and
ornamental crops. Insufficient data are available to evaluate or
predict the short-term effects of aldrin to 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.
Aldrin has high chronic toxicity to aquatic life. Insufficient data
are available to evaluate or predict the long-term effects of
aldrin to plants, birds, or land animals.
WATER SOLUBILITY
Aldrin is slightly soluble in water. Concentrations of 1 milligram
or less will mix with a liter of water.
DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT
Aldrin 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.
Under aerobic (oxygenated) conditions, aldrin is oxidized to the
highly persistent insecticide, dieldrin.
About 49% of aldrin will eventually end up in terrestrial soils;
about 46% in aquatic sediments; and the rest 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 aldrin found in fish tissues is expected to be
much higher than as the average concentration of aldrin in the
water from which the fish was taken.
