EMERGENCY OVERVIEW
Appearance: white powder.
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
Eye:
Causes severe eye irritation.
Skin:
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,
Ingestion:
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.
Inhalation:
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.
Chronic:
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 exposure may damage the liver and kidneys and affect the
heart. 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
|
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid imme
diately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
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:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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.

Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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.
Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid contact with
eyes, skin, and clothing. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
