**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. Danger of cumulative effects.
May cause long-term adverse effects in the aquatic
environment.Toxic.
Potential Health Effects
Eye:
Causes eye irritation. May result in corneal injury. May cause
pink, puffy eyelids due to an allergic reaction.
Skin:
May cause skin irritation. Prolonged and/or repeated contact may
cause irritation and/or dermatitis. May be absorbed through the skin.
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. May cause liver and
kidney damage. May be harmful if swallowed. May cause alopecia (loss
of hair). May cause spleen damage. May cause blood abnormalities.
Effects may be delayed. May cause garlic smell on the breath and
body.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. May produce anemia, leucocytosis
(increase in the white blood cell count) , cloudy swelling and fatty
degeneration of the viscera.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
reproductive and fetal effects. 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
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
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:
Do not induce vomiting. 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 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:
**** 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
extinguishing media appropriate to the surrounding fire. Substance is
noncombustible.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Use water spray, dry chemical, carbon
dioxide, or chemical foam.
**** 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. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Avoid
contact with skin and eyes. Keep container tightly closed. Avoid
ingestion and inhalation. Use with adequate ventilation.
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 process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.
