Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: white crystals.
Danger! May be fatal if inhaled, absorbed through
the skin or swallowed. Causes eye and skin irritation and possible
burns. Causes digestive and respiratory tract irritation with
possible burns. Light sensitive. Hygroscopic (absorbs moisture from
the air).
Target Organs: None.
Potential Health Effects
Eye:
Exposure to mercury or mercury compounds can cause discoloration on
the front surface of the lens, which does not interfere with vision.
Causes eye irritation and possible burns.
Skin:
Causes skin irritation and possible burns.
Ingestion:
May be fatal if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. Metabolism may release cyanide, which
may result in headache, dizziness, weakness, collapse,
unconsciousness and possible death. Inorganic mercury compounds may
cause central and peripheral nervous system effects.
Inhalation:
Causes respiratory tract irritation with possible burns. Acute
exposure to high concentrations of mercury vapors may cause severe
respiratory tract irritation.
Chronic:
Chronic ingestion may cause accumulation of mercury in body tissues.
Chronic exposure to mercury compounds may produce immunologic
glomerular disease. Chronic exposure to cyanide solutions may lead to
the development of a "cyanide" rash, characterized by itching, and by
macular, papular, and vesicular eruptions, and may be accompanied by
secondary infections.

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 immediately. 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:
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.

Use agent most appropriate to extinguish fire. 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:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Avoid contact with eyes, skin, and clothing. Avoid ingestion and
inhalation. Store protected from light. Avoid mechanical shock and
friction.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Poison room locked. Keep containers tightly closed.
Store protected from light.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
