Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. Danger of cumulative effects.Possible risks of irreversible effects.
Potential Health Effects
Eye:
Causes eye irritation. May cause transient keratitis.
Skin:
Causes skin irritation. May be absorbed through damaged or abraded skin in harmful amounts. May cause skin eruptions.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause excessive salivation, teeth decay or discoloration, odorous "garlic" breath and partial loss of hair and nails. May cause central nervous system effects including nervousness, drowsiness and convulsions.
Inhalation:
Causes respiratory tract irritation. Can produce delayed pulmonary edema. Inhaltion may cause coating of the tongue, anemia, irritation of the mucous membrane, lumbar pain, and possible liver and spleen damage.
Chronic:
Prolonged or repeated skin contact may cause sensitization dermatitis and possible destruction and/or ulceration. Chronic exposure to selenium may cause pallor, garlic breath, metallic taste, anemia, liver and spleen damage.

Section 4 - FIRST AID MEASURES
Eyes: Immediately 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. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid immediately.
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.
Notes to Physician:
Due to delayed and persistent symptoms, observe patient closely for 48 hours. Persons with asthma, allergies, hypersensitivity, pre-existing insult to the eyes, skin, or respiratory tract, and diseases of the lung, kidney, and liver may be at increased risk from exposure to this product. Monitor pulmonary function closely.
Treatment options include ipecac/lavage, activated charcoal, cathartics--admisitered within two hours of ingestion. Treat symptomatically and supportively.
Antidote: None reported.

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. Water runoff can cause environmental damage. Dike and collect water used to fight fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
For small fires, use water spray, dry chemical, carbon dioxide or chemical foam. Use extinguishing media most appropriate for the surrounding fire. For large fires, use water spray, fog or regular foam.
