Identification |
EMERGENCY OVERVIEW
Appearance: colorless or white solid. Danger! Strong
oxidizer. Contact with other material may cause a fire. Corrosive. Causes eye
and skin burns. May cause severe respiratory tract irritation with possible
burns. May cause severe digestive tract irritation with possible burns.
Blue-gray permanent discoloration of the skin, conjunctiva, and internal organs,
known as argyria or argyrosis, results from chronic exposure to silver or silver
salts.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye: Causes eye burns. May cause chemical
conjunctivitis and corneal damage.
Skin: Causes skin burns.
May be absorbed through the skin.
Ingestion: Causes
gastrointestinal tract burns. May cause systemic effects. Lethal dose for humans
is 2 grams.
Inhalation: Causes severe irritation of upper
respiratory tract with coughing, burns, breathing difficulty, and possible coma.
May cause systemic effects.
Chronic: May cause
methemoglobinemia, which is characterized by chocolate-brown colored blood,
headache, weakness, dizziness, breath shortness, cyanosis (bluish skin due to
deficient oxygenation of blood), rapid heart rate, unconsciousness and possible
death. 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: Get medical aid immediately. Do NOT allow
victim to rub eyes or keep eyes closed. Extensive irrigation with water is
required (at least 30 minutes).
Skin: Get medical aid
immediately. Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before reuse.
Destroy contaminated shoes.
Ingestion: Do not induce
vomiting. 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
immediately.
Inhalation: Get medical aid immediately.
Remove from exposure and move to fresh air immediately. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply artificial
respiration using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician: Treat symptomatically and
supportively.

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. Strong oxidizer. Contact with combustible materials may cause a fire.
During a fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Wear appropriate protective clothing to prevent
contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products.
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. Clean up spills immediately, observing
precautions in the Protective Equipment section. Avoid generating dusty
conditions. Remove all sources of ignition. Provide ventilation. Do not use
combustible materials such as paper towels to clean up spill.
|
Section 7 - Handling
and Storage |
Handling: Wash thoroughly after handling. Minimize
dust generation and accumulation. Do not get in eyes, on skin, or on clothing.
Keep container tightly closed. Do not ingest or inhale. Use with adequate
ventilation. Do not store near combustible materials. Discard contaminated
shoes.
Storage: Keep away from sources of ignition. Do not
store near combustible materials. Keep container closed when not in use. Store
in a tightly closed container. Store in a cool, dry, well-ventilated area away
from incompatible substances. Corrosives area.

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 general or
local exhaust ventilation to keep airborne concentrations below the permissible
exposure limits.
