**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Danger of cumulative effects. Very toxic to aquatic organisms, may
cause long-term adverse effects in the aquatic environment.Light
sensitive.Toxic.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
May cause erythema (redness) and edema (fluid buildup) with crusting
and scaling.
Ingestion:
Harmful if swallowed. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause kidney damage. Mercaptans
may cause nausea and headache. Exposure to high concentrations of
mercaptans can produce unconsciousness with cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood),
cold extremities and rapid pulse. May cause central nervous system
effects and/or neurological effects. Human fatalities have been
reported from acute poisoning.
Inhalation:
Causes respiratory tract irritation. May cause kidney damage. May
cause allergic respiratory tract irritation. Exposure to high
concentrations of mercaptans can produce unconsciousness with
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), cold extremities and rapid pulse. Mercaptans may
cause nausea and headache. Can produce delayed pulmonary edema.
Acute exposure to high concentrations of mercury vapors may cause
severe respiratory tract irritation. May cause central, peripheral,
and autonomic nervous system effects.
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 ingestion may result
in salicylism which is characterized by nausea, vomiting,
gastrointestinal ulcers, and hemorrhagic strokes. Adverse
reproductive effects have been reported in animals. 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.
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:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively. The concentration of mercury
in whole blood is a reasonable measure of the body-burden of mercury
and thus is used for monitoring purposes.
**** 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 water
spray to keep fire-exposed containers cool. Containers may explode
when heated. Non-combustible, substance itself does not burn but may
decompose upon heating to produce irritating, corrosive and/or toxic
fumes.
Extinguishing Media:
Do NOT get water inside containers. For small fires, use dry
chemical, carbon dioxide, or water spray. For large fires, use water
spray, fog or regular foam. Cool containers with flooding quantities
of water until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
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. Remove all sources of
ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Minimize dust generation and accumulation. Avoid breathing dust,
vapor, mist, or gas. Avoid contact with eyes, skin, and clothing.
Keep container tightly closed. Avoid ingestion and inhalation. Use
with adequate ventilation. Store protected from light. Wash clothing
before reuse.
Storage:
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 moisture. Store protected from
light. Store with desiccant.
**** 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.
