**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic in contact with skin and if swallowed. Danger of
cumulative effects. Causes burns. Contact with combustible material
may cause fire.Possible risks of irreversible effects.
Potential Health Effects
Eye:
May cause eye irritation. Exposure to mercury or mercury compounds
can cause discoloration on the front surface of the lens, which does
not interfere with vision.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. Skin absorption is
slight. May cause severe irritation and possible burns.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. May cause muscle tremor and impaired motor function.
Causes severe pain, nausea, vomiting, diarrhea, and shock. Can cause
nervous system damage.
Inhalation:
May cause gastrointestinal effects including gum and mouth
inflammation, jaw necrosis, and loosening of the teeth. May cause
effects similar to those described for ingestion. May cause lung
damage.
Chronic:
Prolonged or repeated skin contact may cause sensitization
dermatitis and possible destruction and/or ulceration. Chronic
inhalation and ingestion may cause effects similar to those of acute
inhalation and ingestion. May cause liver and kidney damage. May
cause reproductive and fetal effects. Repeated exposure may cause
central nervous system damage.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Destroy contaminated shoes.
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. Call a poison
control center.
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:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Evacuate area and fight fire from a safe distance. Oxidizer. Greatly
increases the burning rate of combustible materials.
Extinguishing Media:
Use alcohol foam, carbon dioxide, or water spray when fighting fires
involving this material.
**** 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Do not get in eyes, on skin, or on clothing.
Do not ingest or inhale. Keep from contact with clothing and other
combustible materials. Discard contaminated shoes.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Keep away from food and drinking water. Keep containers tightly
closed.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits.
