**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation. Danger of cumulative effects.Corrosive.
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. Contact with mercury or
mercury compounds can cause ulceration of the conjunctiva and
cornea.
Skin:
May be absorbed through the skin in harmful amounts. May cause skin
sensitization, an allergic reaction, which becomes evident upon
re-exposure to this material. Causes skin irritation and possible
burns. May cause skin rash (in milder cases), and cold and clammy
skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. May
cause perforation of the digestive tract. May cause effects similar
to those for inhalation exposure. May cause systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. 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
central nervous system effects including vertigo, anxiety,
depression, muscle incoordination, and emotional instability.
Aspiration may lead to pulmonary edema. May cause systemic effects.
May cause respiratory sensitization.
Chronic:
May cause liver and kidney damage. May cause reproductive and fetal
effects. Effects may be delayed. Chronic exposure to mercury may
cause permanent central nervous system damage, fatigue, weight loss,
tremors, personality changes. Chronic ingestion may cause
accumulation of mercury in body tissues. Prolonged or repeated
exposure may cause inflammation of the mouth and gums, excessive
salivation, and loosening of the teeth.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
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. 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. Wash mouth out with
water.
Inhalation:
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:
The concentration of mercury in whole blood is a reasonable measure
of the body-burden of mercury and thus is used for monitoring
purposes. Treat symptomatically and supportively. Persons with
kidney disease, chronic respiratory disease, liver disease, or skin
disease may be at increased risk from exposure to this substance.
Antidote:
The use of d-Penicillamine as a chelating agent should be determined
by qualified medical personnel. The use of Dimercaprol or BAL
(British Anti-Lewisite) as a chelating agent should be determined by
qualified medical personnel.
**** 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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. During a fire, irritating and
highly toxic gases may be generated by thermal decomposition or
combustion.
Extinguishing Media:
Substance is nonflammable; use agent most appropriate to extinguish
surrounding 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:
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. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Keep
container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Use only in a chemical fume hood. Discard
contaminated shoes. Do not breathe vapor.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from metals. Store protected from
azides.
**** 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 only under a
chemical fume hood.
