SECTION 3: Hazards Identification
Emergency Overview:	Toxic by inhalation and if swallowed. Causes nausea, dizziness, and coma. Harmful in contact with skin. May cause cancer. Chronic effects include dermatitis, liver and kidney damage.
Primary Routes of Exposure:	Ingestion, inhalation, skin and eyes
Eye Contact:	Dust may cause moderate irritation of the eyes.
Skin Contact:	Harmful in contact with skin. May cause irritation of the skin, ulceration, spotty pigmentation, dermatitis, and skin cancer.
Inhalation:	Toxic by inhalation. May induce perforation of the nasal septum and cause arsenic poisoning. Hydrogen sulfide gas, if formed, is poisonous.
Ingestion:	Toxic by ingestion. Ingestion of arsenic may lead to nausea, vomiting, bloody diarrhea, weakness, low blood pressure, shock, coma, and death.
Acute Health Effects:	Toxic by inhalation and if swallowed. Causes nausea, dizziness, and coma. Harmful in contact with skin. May cause cancer. Forms toxic hydrogen sulfide gas on exposure to acids or stomach fluids.
Chronic Health Effects:	Prolonged exposure to arsenic compounds may cause loss of appetite, dermatitis, diarrhea, liver damage, nervous disorders, and cancer of the skin, lungs, and liver. May cause cancer.
NTP:	yes
IARC:	Yes
OSHA:	Yes

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
Flash Point:	not applicable
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	carbon dioxide or dry powder
Special Fire Fighting Procedures:	If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self- contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products:	If involved in a fire this material may emit irritating fumes of hydrogen sulfide and sulfur dioxide.
Unusual Fire or Explosion Hazards:	Dust may form explosive mixtures with air. Contact with acids gives off hydrogen sulfide, a toxic and flammable gas.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	In the case of a spill, the fine powder should be covered with dry sodium carbonate or dolomite in order to reduce the formation of dust. Sweep up the mixture.

SECTION 7: Handling and Storage
Handling and Storage:	Store in a tightly sealed container. Exposure to the atmosphere may lead to release of toxic hydrogen sulfide gas. Empty containers may retain product residues that evolve toxic gases.

SECTION 8: Exposure Controls and Personal Protection
Eye Protection:	Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection:	Wear appropriate chemical resistant gloves and protective clothing.
Ventilation:	If possible, handle the material in an efficient fume hood.
Respirator:	If ventilation is not available a respirator should be worn. The use of a respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	No additional protection required.
