Section 3 - Hazards Identification
Appearance: white to light beige crystals.
Danger! May be fatal if swallowed. Poison! Causes
eye and skin irritation. May be harmful if absorbed through the
skin. Causes digestive and respiratory tract irritation. May cause
reproductive and fetal effects.
Target Organs: Kidneys, liver.
Potential Health Effects
Causes severe eye irritation.
Causes skin irritation. May be absorbed through the skin in harmful
amounts. Chronic exposure to selenium may cause central nervous
system effects, digestive tract disturbances, pallor, garlic breath,
May be fatal if swallowed. Poison by ingestion. Causes
gastrointestinal irritation with nausea, vomiting and diarrhea. May
cause liver and kidney damage. May cause cardiac abnormalities.
Causes respiratory tract irritation. Irritation may lead to chemical
pneumonitis and pulmonary edema. Inhalation of fumes may cause metal
fume fever, which is characterized by flu-like symptoms with
metallic taste, fever, chills, cough, weakness, chest pain, muscle
pain and increased white blood cell count.
May cause reproductive and fetal effects. Chronic exposure to
selenium may cause central nervous system effects, digestive tract
disturbances, pallor, garlic breath, Laboratory experiments have
resulted in mutagenic effects.
Chronic selenium poisoning resembles arsenic poisoning. Nausea,
vomiting leukocytosis, white streaks in the nails, loss of hair,
skin rashes, irritability, fatigue, hyperflexia, and EKG changes.
Section 4 - First Aid Measures
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
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
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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
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.
In case of fire, use water, dry chemical, chemical foam, or

Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Avoid ingestion and inhalation.
Store in a cool, dry place. Keep container closed when not in use.
Section 8 - Exposure Controls, Personal Protection
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
