**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful to aquatic organisms, may cause long-term adverse effects in
the aquatic environment.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin discoloration.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause methemoglobinemia, cyanosis (bluish discoloration
of skin due to deficient oxygenation of the blood), convulsions, and
death. Methemoglobinemia is characterized by dizziness, drowsiness,
headache, shortness of breath, cyanosis (bluish discoloration of
skin due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood.
Inhalation:
Causes respiratory tract irritation.
Chronic:
Chronic inhalation or ingestion of silver salts may cause argyria
characterized by a permanent blue-gray discoloration of the eyes,
skin, mucous membranes, and internal organs. This malady results
from the accumulation of silver in the body.
**** 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:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
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 if cough or other symptoms appear.
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. Dried product residue is a strong oxidizer.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Use with
adequate ventilation. Avoid contact with eyes, skin, and clothing.
Avoid ingestion and inhalation. Use with adequate ventilation. Do
not allow to dry on clothing. Drying on clothing or other
combustible materials may cause fire.
Storage:
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 adequate
ventilation to keep airborne concentrations low.
