**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Light sensitive.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May cause skin irritation. May cause severe irritation and possible
burns.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema.
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
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
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.
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. 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:
Use agent most appropriate to extinguish fire. Use water spray, dry
chemical, carbon dioxide, or appropriate foam.
**** 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 generating dusty conditions. Remove all sources of
ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Keep
container tightly closed. Avoid contact with clothing and other
combustible materials. Do not get on skin or in eyes. Do not ingest
or inhale. Store protected from light. Do not store near combustible
materials.
Storage:
Keep away from sources of ignition. Do not store near combustible
materials. Store in a tightly closed container. Store in a cool,
dry, well-ventilated area away from incompatible substances. Store
protected from light.
**** 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.
Exposure Limits
CAS# 20667-12-3:

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:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
