**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Light sensitive.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause effects similar to those for inhalation
exposure.
Inhalation:
May cause respiratory tract irritation. May cause central nervous
system effects including vertigo, anxiety, depression, muscle
incoordination, and emotional instability.
Chronic:
Chronic exposure to mercury may cause permanent central nervous
system damage, fatigue, weight loss, tremors, personality changes.
**** 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 immediately. Immediately flush skin with plenty of
soap and water for at least 15 minutes while removing contaminated
clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Get medical aid immediately.
Inhalation:
Remove from exposure 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 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. 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:
Wash area with soap and water. 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:
Wash thoroughly after handling. Use with adequate ventilation. Avoid
contact with eyes, skin, and clothing. Avoid ingestion and
inhalation.
Storage:
Store in a cool, dry place. Do not store in direct sunlight. Store
in a tightly closed container. Keep from contact with oxidizing
materials.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits.
Personal Protective Equipment
Eyes:
Wear chemical goggles. Wear appropriate protective
eyeglasses or chemical safety goggles as described by
OSHA's eye and face protection regulations in 29 CFR
1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
