**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes, respiratory system and
skin. Very toxic to aquatic organisms, may cause long-term adverse
effects in the aquatic environment.Moisture sensitive.Toxic.
Potential Health Effects
Eye:
May cause eye irritation. Contact may cause ulceration of the
conjunctiva and cornea.
Skin:
May cause skin irritation. May be absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause kidney damage. May cause severe
digestive tract irritation with abdominal pain, nausea, vomiting and
diarrhea. May cause central nervous system depression. Inorganic
mercury compounds may cause central and peripheral nervous system
effects.
Inhalation:
May cause respiratory tract irritation. Irritation may lead to
chemical pneumonitis and pulmonary edema. May cause gastrointestinal
effects including gum and mouth inflammation, jaw necrosis, and
loosening of the teeth. May cause kidney damage. Acute exposure to
high concentrations of mercury vapors may cause severe respiratory
tract irritation.
Chronic:
May cause kidney injury. May cause reproductive and fetal effects.
Chronic exposure to mercury may cause permanent central nervous
system damage, fatigue, weight loss, tremors, personality changes.
May cause tremors, irritability, loss of memory and intellect. May
also cause Pink disease characterized by skin, cardiovascular, and
neurobehavioral abnormalities. 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:
Immediately 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. 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. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Antidote:
The use of a metal chelator should be determined only 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. 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.
**** 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. Wash area with soap and water. Clean up spills
immediately, observing precautions in the Protective Equipment
section. Avoid generating dusty conditions. Isolate area and deny
entry. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Do not ingest or inhale. Use only in a chemical fume hood.
Storage:
Do not store in direct sunlight. 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 only under a
chemical fume hood.
