**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Toxic if swallowed. Causes burns. Toxic : danger of serious damage
to health by prolonged exposure in contact with skin and if
swallowed.Light sensitive.Corrosive.Toxic.

Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May cause skin rash (in milder cases), and cold
and clammy skin with cyanosis or pale color.
Ingestion:
May be fatal if swallowed. May cause severe and permanent damage to
the digestive tract. Causes gastrointestinal tract burns. May cause
perforation of the digestive tract. Inorganic mercury compounds may
cause central and peripheral nervous system effects. May cause
systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects. Acute exposure to
high concentrations of mercury vapors may cause severe respiratory
tract irritation.
Chronic:
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. Chronic exposure to mercury
vapors may produce weakness, fatigue, anorexia, loss of weight and
gastrointestinal disturbances which is collectively referred to as
asthenic-vegetative syndrome or micromercurialism. Chronic exposure
to mercury compounds may produce immunologic glomerular disease.

**** 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:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
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:

**** 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.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant 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, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Use only in a well-ventilated area. Minimize dust generation and
accumulation. Do not breathe dust, vapor, mist, or gas. Do not get in
eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale. Store protected from light. Discard contaminated
shoes.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area. Store protected from light.

**** 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
ventilation to keep airborne concentrations low.
