**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes and skin. Contact with combustible material may
cause fire.Oxidizer.Light sensitive.
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract. 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. Ingestion of soluble silver salts may
cause argyria, characterized by permanent blue-gray pigmentation of
the skin, mucous membranes, and eyes. Ingestion of silver compounds
may cause abdominal pain, rigidity, convulsions and shock.
Inhalation:
Inhalation of dust may cause respiratory tract irritation.
Chronic:
No information found.
**** 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
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Remove
contaminated clothing and shoes.
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 immediately.
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:
**** 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 other material may
cause fire.
Extinguishing Media:
Use water only! Contact professional fire-fighters immediately. Do
NOT use dry chemicals, CO2, Halon or foams.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Remove all sources of ignition. In case of spill,
sweep up solid or absorb liquid with inert material, then place into
a biohazard container. Wear protective equipment.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with eyes,
skin, and clothing. Keep container tightly closed. Avoid contact with
clothing and other combustible materials. Avoid ingestion and
inhalation.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a tightly closed container.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7783-99-5:
Japan: (listed as silver compounds): 0.01 mg/m3 OEL (as Ag)
Personal Protective Equipment
Eyes:
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 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
