Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE/CHRONIC:THIS MATERIAL IS
    CORROSIVE TO ALL BODY TISSUES. (HNO*3) EXTREMELY DESTRUCTIVE TO
    TISSUE OF THE MUCOUS MEMBRANES, UPPER RESPIRATORY TRACT, EYES AND
    SKIN. INHALATION MAY BE FATAL. (A*GNO*3 ) SIGNS AND
    SYMPTOMS:IRRITATION, DIFFICULTY BREATHING, BURNING SENSATION,
    YELLOW SKIN DISCOLORATION. (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZS:(HNO*3) BURNING SENSATION, COUGHING,
    WHEEZING, LARYNGITIS, SHORTNESS OF BREATH, HEADACHE, NAUSEA AND
    VOMITING. PROLONGED ABSORPTION OF SILVER COMPOUNDS CAN LEAD TO
    ARGYRIA - A GRAYISH BLUE D ISCOLORATION OF THE SKIN. HIGHLY
    CORROSIVE TO SKIN, EYES AND INTESTINAL TRACT. (A*GNO*3)
Medical Cond Aggravated by Exposure:IRRITATION OF EYES, SKIN, LUNGS,
    CAN CAUSE PERMANENT BLINDNESS OR MAY BE FATAL. (HNO*3) IRRITATION
    OF THE SKIN AND MUCOUS MEMBRANES. SHOCK CAN RESULT FROM INGESTION.
    (A*GNO*3)

=======================  First Aid Measures  =======================

First Aid:EYE:IMMED FLUSH W/WATER FOR 15 MIN, INCLUDING UNDER EYELIDS.
    REMOVE ANY CLTHG THAT IS CONTAM. CONT MD. SKIN:WASH IMMED W/SOAP &
    WATER. REMOVE CONTAM CLTHG UNDER SFTY SHOWER. GET MED ATTN.
    INHAL:REMOVE  TO FRESH AIR. ADMIN O*2 IF NEC & GET MED ATTN.
    INGEST:IF CONSCIOUS, GIVE 2-3 GLASSES WATER, THEN MILK
    MAGNESIA/LIMEWATER. CONTACT MD. DO NOT INDUCE VOMIT.

=====================  Fire Fighting Measures  =====================

Flash Point:NONFLAMMABLE
Extinguishing Media:USE WATER ON FIRES INVOLVING NITRIC ACID TO DILUTE
    THE ACID AND TO ABSORB THE LIBERATED OXIDES OF NITROGEN.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPROVED SCBA & FULL
    PROTECTIVE EQUIPMENT .
Unusual Fire/Explosion Hazard:NON FLAMMABLE, HOWEVER, A STRONG
    OXIDIZING AGENT WHICH CAN REACT WITH COMBUSTIBLE MATERIALS TO CAUSE
    FIRES.

==================  Accidental Release Measures  ==================

Spill Release Procedures:PROVIDE ADEQUATE VENTILATION. REMOVE SOURCES
    OF IGNITION. SURFACES CONTAMINATED BY SPILLS SHOULD BE COVERED WITH
    SODIUM BICARBONATE OR SODA ASH TO NEUTRALIZE THE ACID. WASH THE
    NEUTRALIZED SLURRY DOWN  THE DRAIN WITH EXCESS WATER.
Neutralizing Agent:SODIUM BICARBONATE OR SODA ASH.

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE CNTNRS IN CLEAN, COOL, WELL-VENT
    AREA AWAY FROM ORGANIC CHEMS, STRONG BASES, METAL POWDERS,
    CARBIDES, SULFIDES, & ANY READILY OXIDIZABLE MATL.
Other Precautions:PROT FROM DIRECT SUNLIGHT. PREPLACEMENT & ANNUAL MED
    EXAMINATIONS W/EMPHASIS ON RESP TRACT, SKIN IRRITS, DENTAL EROSION,
    & LUNG FUNCTION TESTS, SHOULD BE PROVIDED TO WORKERS FREQUENTLY
    EXPOSED TO NITR IC ACID. WHEN GASEOUS NO*X FORMS(ING 4)

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:USE NIOSH/MSHA APPROVED RESPIRATOR APPROPRIATE
    FOR EXPOSURE OF CONCERN .
Ventilation:THE NITROGEN OXIDES PRODUCED FROM THE ACID ARE ALL TOXIC,
    AND PROPER VENTILATION SHOULD ALWAYS BE USED.
Protective Gloves:NEOPRENE GLOVES.
Eye Protection:ANSI APP CHEM WKR GOGS & FFSHLD .
Other Protective Equipment:BODY SHIELDS SHOULD BE USED WHERE SPLASHING
    MAY OCCUR. CHEM SFTY SHOWERS & EYEWASH STATIONS MUST BE READILY
    AVAIL(ING 5)
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
APPEAR/ODOR:ODOR. SILVER NITRATE:RHOMBIC, WHITE CYRSTALS THAT TURN GRAY
    WHEN EXPOS TO LIGHT. MATLS TO AVOID:MAGNESIUM, & ANY OF
