present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.
Section 7. Handling and Storage
Precautions Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not
ingest. Do not breathe dust. Wear suitable protective clothing. In case of insufficient ventilation, wear
suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the
label. Keep away from incompatibles such as oxidizing agents, acids.
Storage Keep container tightly closed. Keep container in a cool, well-ventilated area.
Section 8. Exposure Controls/Personal Protection
Engineering Controls Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep
exposure to airborne contaminants below the exposure limit.

Chronic Effects on Humans
Special Remarks on other Acute Potential Health Effects:
Toxic Effects on Humans Skin: May cause skin irritation. May be absorbed through intact skin and cause system effects.
Eyes: May cause eye irritation.
Inhalation: Can cause respiratory tract irritation with cough, breathing difficulity, chest pain. May cause
damage to respiratory tract.
Ingestion: Can cause severe gastrointestinal tract damage, including vomiting, diarrhea, and shock. Can
also cause alopecia, burning lips, garlic odor of breath, facial swelling, throat constriction and dysphagia,
intense thirst, muscle cramps, cardiac abnormalities, bone marrow suppression, anemia, deceased white
blood cell count, kidney failure, enlargement of liver, progessive hypotension, refractory ventricular fibrillation,
irreversible cardiac arrest . Also affects nervous system involving both sensory and motor peripheral
polyneuropathies. Neurological symptoms can include headache, lethargy, mental confusion, hallucinations,
emotional lability, memory loss, delirium, seizures, stupors, convulsions, coma.
Chronic Potential Health Effects:
Ingestion: Can cause hyperpigemtation of skin, particularly on palms of skin and hands and soles of feet,
gangrene, anemia, cirrhosis of liver.
Inhalation: Can cause perforation of the nasal septum.
Similar systemic effects can occur with chronic arsenic poisoning, via inhalation or ingestion. Chronic
(systemic)arsenic poisoning may also occur if it is absorbed through the skin.
The major target organs for arsenic toxicity are the nerves, heart, blood/bone marrow, and liver. Nervous
damage can be both central (encephalopathy) and peripheral (peripheral polyneuropathy). Early symptoms of
peripheral nerve damage include pain, numbness, tingling, a pins-and-needles sensation in the extremities,
loss of touch sensation, foot or wrist drop, and muscle cramps. Effects on the heart include ECG
abnormalities and fibrillation. Arsenic can depress formation of all the blood elements in the bone marrow,
causing aplastic anemia. Both cirrhosis and cancer of the liver have been reported with chronic arsenic
