Material Safety Data Sheet- Lithium Chromate



CAS Number: 14307-35-8
DOT Number: NA 9134


* Lithium Chromate can affect you when breathed in.
* Contact can cause severe skin and eye irritation and burns.
* Breathing Lithium Chromate can irritate the nose, throat and lungs.
* Repeated exposure can cause loss of appetite, nausea,
   tremor, convulsions and personality changes.
* Lithium Chromate may cause a skin allergy. If allergy
  develops, very low future exposure can cause itching and a skin rash.
* Prolonged exposure may cause deep slow-healing ulcers on
  the skin and a sore or a hole in the bone dividing the inner nose (septum).
* Lithium Chromate may damage the liver and kidneys.


Lithium Chromate is a yellow powder used as a corrosion
inhibitor, heat transfer agent, and oxidizing agent in leather
and metal finishing. It is also used in photography, wood
preservatives, batteries, safety matches and cement.


* Lithium Chromate is on the Hazardous Substance List
because it is regulated by OSHA and cited by ACGIH,


The New Jersey Right to Know Act requires most employers
to label chemicals in the workplace and requires public
employers to provide their employees with information and
training concerning chemical hazards and controls. The
federal OSHA Hazard Communication Standard, 1910.1200,
requires private employers to provide similar training and
information to their employees.

* 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 1910.2

* 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.
RTK Substance number: 1125

Date: August 1998



The following exposure limits are for hexavalent Chromium
compounds (measured as Chromium):

OSHA: The legal airborne permissible exposure limit
(PEL) is 0.1 mg/m 3 not to be exceeded at any time.

NIOSH: The recommended airborne exposure limit is
0.001 m
g/m 3 averaged over a 10-hour workshift.

ACGIH: The recommended airborne exposure limit is
0.05 m
g/m 3 averaged over an 8-hour workshift.


* 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 Lithium
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 Lithium Chromate 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.



Acute Health Effects
The following acute (short-term) health effects may occur
immediately or shortly after exposure to Lithium Chromate:
Contact can cause severe skin and eye irritation and burns.
* Breathing Lithium Chromate can irritate the nose and
throat causing coughing and wheezing.
* Repeated exposure can cause loss of appetite, nausea, tremor, and convulsions.

Chronic Health Effects
The following chronic (long-term) health effects can occur at
some time after exposure to Lithium Chromate and can last for months or years:

Cancer Hazard
* While Lithium Chromate has not been identified as a
carcinogen, certain kinds of Chromium compounds, known
as hexavalent Chromium or Chromium VI compounds,
have been determined to be human carcinogens. Lithium
is such a compound and should be handled with extreme caution.

Reproductive Hazard
* While Lithium Chromate has not been identified as a
reproductive hazard, it should be HANDLED WITH
CAUTION since several related Chromium compounds are teratogenic.

Other Long-Term Effects
* Lithium Chromate can irritate the lungs. Repeated
exposure may cause bronchitis to develop with cough,
phlegm, and/or shortness of breath.
* Lithium Chromate may cause a skin allergy. If allergy
develops, very low future exposure can cause itching and a skin rash.
* Repeated exposure may cause personality changes of
depression, anxiety or irritability.
* Prolonged exposure may cause deep slow-healing ulcers on
the skin and a sore or hole in the bone dividing the inner nose (septum).
* Lithium Chromate may damage the liver and kidneys.


Medical Testing
For those with frequent or potentially high exposure (half the
TLV or greater, or significant skin contact), the following are
recommended before beginning work and at regular times after that:
* Lung function tests.
* Evaluation by a qualified allergist, including careful
exposure history and special testing, may help diagnose skin allergy.
* Liver and kidney function tests.
* Check your skin daily for little bumps or blisters, the first
sign of "Chrome ulcers." If not treated early, these can last
for years after exposure.
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.

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 Lithium Chromate
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
Lithium Chromate
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 Lithium Chromate.

* Eye wash fountains should be provided in the immediate
work area for emergency use.

* If there is the possibility of skin exposure, emergency
shower facilities should be provided.

* On skin contact with Lithium Chromate, immediately
wash or shower to remove the chemical. At the end of the
workshift, wash any areas of the body that may have
contacted Lithium Chromate, whether or not known skin contact has occurred.

* Do not eat, smoke, or drink where Lithium Chromate is
handled, processed, or stored, since the chemical can be
swallowed. Wash hands carefully before eating, drinking,
smoking, or using the toilet.

* Use a vacuum or a wet method to reduce dust during
clean-up. DO NOT DRY SWEEP.


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.

OSHA 1910.132 requires employers to determine the
appropriate personal protective equipment for each hazard and
to train employees on how and when to use protective equipment.

The following recommendations are only guidelines and may
not apply to every situation.

* Avoid skin contact with Lithium Chromate. 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
* Wear non-vented, impact resistant goggles when working
   with fumes, gases, or vapors.
* Contact lenses should not be worn when working with this substance.

Respiratory Protection
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.

* NIOSH has established new testing and certification
requirements for negative pressure, air purifying,
particulate filter and filtering facepiece respirators. The
filter classifications of dust/mist/fume, paint spray or
pesticide prefilters, and filters for radon daughters, have
been replaced with the N, R, and P series. Each series has
three levels of filtering efficiency: 95%, 99%, and 99.9%.
Check with your safety equipment supplier or your
respirator manufacturer to determine which respirator is
appropriate for your facility.

* If while wearing a filter or cartridge respirator you can
smell, taste, or otherwise detect Lithium Chromate, or if
while wearing particulate filters abnormal resistance to
breathing is experienced, or eye irritation occurs while
wearing a full facepiece respirator, leave the area
mmediately. Check to make sure the respirator-to-face seal
is still good. If it is, replace the filter or cartridge. If the
seal is no longer good, you may need a new respirator.
* Be sure to consider all potential exposures in your
workplace. You may need a combination of filters,
prefilters or cartridges to protect against different forms of
a chemical (such as vapor and mist) or against a mixture of chemicals.

* Where the potential exists for exposure over 0.001 mg/m 3
(as Chromium VI), use a MSHA/NIOSH approved
supplied-air respirator with a full facepiece operated in a
pressure-demand or other positive-pressure mode. For
increased protection use in combination with an auxiliary
self-contained breathing apparatus operated in a pressure-demand
or other positive-pressure mode.

* Exposure to 15 mg/m 3 (as Chromium VI) is immediately
dangerous to life and health. If the possibility of exposure
above 15 mg/m 3 (as Chromium VI) exists, use a

MSHA/NIOSH approved self-contained breathing
apparatus with a full facepiece operated in a pressure-demand
or other positive-pressure mode.


Q: If I have acute health effects, will I later get chronic health effects?
A: Not always. Most chronic (long-term) effects result
from repeated exposures to a chemical.

Q: Can I get long-term effects without ever having short-term effects?
A: Yes, because long-term effects can occur from repeated
exposures to a chemical at levels not high enough to make you immediately sick.

Q: What are my chances of getting sick when I have been exposed to chemicals?
A: The likelihood of becoming sick from chemicals is
increased as the amount of exposure increases. This is
determined by the length of time and the amount of
material to which someone is exposed.

Q: When are higher exposures more likely?
A: Conditions which increase risk of exposure include dust
releasing operations (grinding, mixing, blasting,
dumping, etc.), other physical and mechanical processes
(heating, pouring, spraying, spills and evaporation from
large surface areas such as open containers), and
"confined space" exposures (working inside vats,
reactors, boilers, small rooms, etc.).

Q: Is the risk of getting sick higher for workers than for community residents?
A: Yes. Exposures in the community, except possibly in
cases of fires or spills, are usually much lower than those
found in the workplace. However, people in the
community may be exposed to contaminated water as
well as to chemicals in the air over long periods. This
may be a problem for children or people who are already ill.

Q: Don't all chemicals cause cancer?
A: No. Most chemicals tested by scientists are not cancer-causing.

Q: Should I be concerned if a chemical is a teratogen in animals?
A: Yes. Although some chemicals may affect humans
differently than they affect animals, damage to animals
suggests that similar damage can occur in humans.
