**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed.Cancer suspect agent.
Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May cause skin irritation. Exposure to arsenic compounds may produce
hyperpigmentation of the skin and hyperkeratoses of plantar and
palmar surfaces as well as both primary irritation and sensitization
types.
Ingestion:
May cause irritation of the digestive tract. The toxicological
properties of this substance have not been fully investigated.
Ingestion of arsenical compounds may cause burning of the lips,
throat constriction, swallowing difficulties, severe abdominal pain,
severe nausea, projectile vomiting, and profuse diarrhea. Ingestion
of arsenic compounds can produce convulsions, coma, and possibly
death within 24 hours.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated. Inhalation of
arsenic compounds may lead to irritation of the respiratory tract and
to possible nasal perforation. Long-term exposure to arsenic
compounds may produce impairment of peripheral circulation.
Chronic:
May cause liver and kidney damage. Chronic exposure to arsenical
dust may cause shortness of breath, nausea, chest pains, and garlic
odor. Cancer suspect agent.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Use water spray, dry
chemical, carbon dioxide, or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Minimize dust generation and accumulation. Avoid
contact with eyes, skin, and clothing. Keep container tightly
closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
