**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Danger of cumulative effects.The toxicological properties of this
material have not been fully investigated.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause kidney
damage. The toxicological properties of this substance have not been
fully investigated. Can cause nervous system damage.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated. Acute exposure to
high concentrations of mercury vapors may cause severe respiratory
tract irritation.
Chronic:
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:
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. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE. Do NOT
induce vomiting. If conscious and alert, rinse mouth and drink 2-4
cupfuls of milk or water. Wash mouth out with 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.
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.
**** 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:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. 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:
Vacuum or sweep up material and place into a suitable disposal
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. Use with adequate ventilation.
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. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Poison room locked.
**** 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.
