Section 3 - HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. Danger of cumulative effects.The toxicological properties of this material have not been fully investigated.
Potential Health Effects
Eye:
Causes eye irritation. May result in corneal injury.
Skin:
Causes skin irritation and possible burns. Contact with the skin may cause the skin to appear to be blue and the nails brittle and yellow.
Ingestion:
May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. May cause alopecia (loss of hair). Effects may be delayed. May cause garlic smell on the breath and body.
Inhalation:
Effects may be delayed. May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Vapor harmful. Vapors may cause dizziness or suffocation. May produce anemia, leucocytosis (increase in the white blood cell count) , cloudy swelling and fatty degeneration of the viscera.
Chronic:
Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath, Chronic exposure to selenium may cause pallor, garlic breath, metallic taste, anemia, liver and spleen damage. Chronic selenium poisoning is characterized by loss of hair and nails, skin lesions, and abnormalities of the nervous system.

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:
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. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:
Treat symptomatically and supportively.

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. Use water spray to keep fire-exposed containers cool. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Cool containers with flooding quantities of water until well after fire is out. 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:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Wash hands before eating. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing.
Keep container tightly closed. Avoid ingestion and inhalation. Use and store under argon. Use only in a chemical fume hood. Wash clothing before reuse.
Storage:
Store in a tightly closed container. Keep under an argon blanket.
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.
Exposure Limits CAS# 6486-05-1: United Kingdom, WEL - TWA: (listed as selenium compounds): 0.1 mg TWA (except hydrogen selenide, as Se) United Kingdom, WEL - STEL: (listed as selenium compounds): 0.3 m STEL (except hydrogen selenide, as Se) United States OSHA: 0.2 mg/m3 TWA (as Se) (listed under Selenium compounds).

Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.
