**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Explosive when mixed with combustible material.
Potential Health Effects
Eye:
May cause severe eye irritation. May result in corneal injury.
Skin:
May cause severe irritation and possible burns.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung 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:
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.
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:
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:
Strong oxidizer. Contact with other material may cause fire. 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:
For small fires, use water spray, dry chemical, carbon dioxide or
chemical 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale. Use
only in a chemical fume hood. Do not store near combustible
materials.
Storage:
Do not store near combustible materials. 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:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 7783-93-9:
Personal Protective Equipment
Eyes:
