ROUTE OF EXPOSURE
skin Contact: Causes skin irritation.
skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes eye irritation.
Inhalation: May be harmful if inhaled. Material is irritating to
mucous membranes and upper respiratory tract
Ingestion: May be
harmful
if swallowed.
TARGET ORGAN(S) OR SYSTEM(S)
Blood. Central nervous system.
SIGNS AND SYMPTOMS OF EXPOSURE
Absorption into the body leads to the formation of methemoglobin
which in sufficient concentration causes cyanosis. Onset may be
delayed 2 to 4 hours or longer. To the best of our knowledge,
the chemical, physical, and toxicological properties have not
been thoroughly investigated.

TARGET ORGAN(S) OR SYSTEM(S)
Nerves. Lungs.
SIGNS AND SYMPTOMS OF EXPOSURE
Men exposed to manganese dusts showed a decrease in fertility.
Chronic manganese poisoning primarily involves the central
nervous system. Early symptoms include languor, sleepiness and
weakness in the legs. A stolid mask-like appearance of the face,
emotional disturbances such as uncontrollable laughter and a
spastic gait with tendency to fall in walking are findings in
more advanced cases. High incidence of pneumonia has been found
in workers exposed to the dust or fume of some manganese
compounds.
CONDITIONS AGGRAVATED BY EXPOSURE
May cause nervous system disturbances. The scientific literature
reports that welders who were chronically exosed to various
Manganese oxides develop Manganism, a illness similar to
Parkinson's disease. Avoid contact with Manganese fumes
associated with welding, oxidizing or melting of Manganese

TARGET ORGAN(S) OR SYSTEM(S)
Lungs. Nerves.
SIGNS AND SYMPTOMS OF EXPOSURE
Men exposed to manganese dusts showed a decrease in fertility.
Chronic manganese poisoning primarily involves the central
nervous system. Early symptoms include languor, sleepiness and
weakness in the legs. A stolid mask-like appearance of the face,
emotional disturbances such as uncontrollable laughter and a
spastic gait with tendency to fall in walking are findings in
more advanced cases. High incidence of pneumonia has been found
in workers exposed to the dust or fume of some manganese
compounds.

Eye Contact: Causes burns.
Inhalation: May be fatal if inhaled. Material is extremely
destructive to the tissue of the mucous membranes and upper
respiratory tract.
Ingestion: May be fatal if swallowed.
TARGET ORGAN(S) OR SYSTEM(S)
Blood. Kidneys. Liver. Nerves. Bones. Spleen.
SIGNS AND SYMPTOMS OF EXPOSURE
Material is extremely destructive to tissue of the mucous
membranes and upper respiratory tract, eyes, and skin.
Inhalation may result in spasm, inflammation and edema of the
larynxand bronchi, chemical pneumonitis, and pulmonary edema.
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Exposure to mercury compounds can cause tremors, loss
of appetite, weight loss, anuria, and uremia. Mercury
accumulates in almost all tissues, especially in the brain,
liver, and kidneys. Ingestion can cause: tremors,
incoordination, insomnia, irritability, fatigue, anxiety,
anorexia, hallucinations, headache, depression, severe
stomatitis, nausea, vomiting, diarrhea, metallic taste, muscle
weakness, loosening of the teeth, pain and numbness in the
extremities, nephritis, peripheral neuropathy, collapse, and
possibly death.

ROUTE OF EXPOSURE
skin Contact: Causes skin irritation.
Multiple Routes: May be harmful by inhalation, ingestion, or
skin absorption. Vapor or mist is irritating to the eyes, mucous
membranes, and upper respiratory tract.
SIGNS AND SYMPTOMS OF EXPOSURE
Absorption into the body leads to the formation of methemoglobin
which in sufficient concentration causes cyanosis. Onset may be
delayed 2 to 4 hours or longer. To the best of our knowledge,
the chemical, physical, and toxicological properties have not
been thoroughly investigated.

Exposure can cause: Narcotic effect. This product is metabolized
into formic acid. Humans and other primates metabolize formic
acid more slowly than do rodents. Formic acid can build up in
the body producing toxic effects possibly leading to death;
therefore, data from studies in rodents may have limited

SIGNS AND SYMPTOMS OF EXPOSURE
To the best of our knowledge, the chemical, physical, and
toxicological properties have not been thoroughly investigated.
In contrast to inorganic mercury compounds, alkyl mercury
compounds rapidly pass through the placenta and blood brain
barrier. The peripheral and central nervous systems and the
kidney are major target organs. Methylmercury poisoning symptoms
result primarily from damage to the nervous system. The symptoms
are primarily characterized by loss of sensation in the hands
and feet and in areas around the mouth, diminution of vision
resulting in tunnel vision, ataxia, dysarthria, and hearing
loss. Severe poisoning produces blindness, coma and death. There
is a latent period of weeks to months before development of the
poisoning symptoms. Mercury shows a specificity to damage small
nerve cells in the cerebellum and visual cortex. Methylmercury
causes degeneration and necrosis of neurons in the focal areas
of the cerebral cortex, especially within the visual areas of
the occipital cortex and the granular layer of the cerebellum.
It has been found that methylmercury inhibits protein synthesis
in the brain before symptoms of poisoning appear and that
recovery of protein synthesis does not occur in granular cells
as it does recover in other neuronal cell types. Consumption by
pregnant women has caused serious neurological disorders in
their offspring resulting in mental retardation with cerebral
palsy.

Symptoms of overexposure can include headache, shallow
respiration, low blood pressure, weight loss, anemia, weakness
and irritability may occur. The liver, kidneys, nervous system
and bone marrow may be affected under chronic exposure
conditions. Absorption into the body leads to the formation of
methemoglobin which in sufficient concentration causes cyanosis.
