Ingestion: YES
Carcinogenicity Inds - NTP: NO
IARC: NO
OSHA: NO
Effects of Exposure: POTENTIAL HEALTH EFFECTS: LIQUID AND VAPOR CAUSE SEVERE
BURNS TO THE EYES, SKIN, NOSE, AND THROAT. HARMFUL IF INHALED AND MAY CAUSE
DELAYED LUNG INJURY. SPILLAGE MAY CAUSE FIRE OR LIBERATE DANGEROUS G AS.
HUMAN HEALTH EFFECTS: OVEREXPOSURE BY SKIN CONTACT MAY INCLUDE SKIN BURNS OR
ULCERATION. EYE CONTACT WITH THE VAPOR MAY INCLUDE EYE IRRITATION WITH
DISCOMFORT, TEARING, OR BLURRING OF VISION; CONT ACT WITH THE LIQUID WILL
CAUSE EYE CORROSION WITH CORNEAL OR CONJUNCTIVAL ULCERATION. (EFTS OF

Explanation Of Carcinogenicity: NONE OF THE COMPONENTS PRESENT IN THIS MATERIAL
AT CONCENTRATIONS EQUAL TO OR GREATER THAN 0.1% ARE LISTED BY IARC, NTP,
OSHA, OR ACGIH AS A CARCINOGEN.
Signs And Symptions Of Overexposure: HEALTH HAZ: INHALATION MAY INCLUDE
IRRITATION OF THE UPPER RESPIRATORY PASSAGES; TEMPORARY LUNG IRRITATION
EFFECTS WITH COUGH, DISCOMFORT, DIFFICULTY BREATHING, OR SHORTNESS OF BREATH;
OR POSSIBLY MOD EST INITIAL SYMPTOMS, FOLLOWED IN HOURS BY SEVERE SHORTNESS
OF BREATH, REQUIRING PROMPT MEDICAL ATTENTION. INGESTION MAY INCLUDE BURINNG
PAIN IN THE MOUTH WITH SEVERE CORROSION OF MUCOSAL SURFACES. P ROLONGED
EXPOSURE TO THE FUMES MAY CAUSE EROSION OF THE TEETH FOLLOWED BY JAW

Medical Cond Aggravated By Exposure: INDIVIDUALS WITH PREEXISTING DISEASES OF
THE LUNGS MAY HAVE INCREASED SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE
EXPOSURES.
First Aid: INHAL: IMMEDIATELY REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN. CALL A
PHYSICIAN. SKIN: IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEA ST 15
MINUTES, WHILE REMOVING CONTAMINATED CLOTHING AND SHOES. CALL A PHYSICIAN.
WASH CONTAMINATED CLOTHING BEFORE REUSE. EYE : IMMEDIATELY FLUSH WITH PLENTY

Handling and Disposal
=======================================================
Spill Release Procedures: SAFEGUARD (PERSONNEL): NOTE: REVIEW FIRE FIGHTING
MEASURES & HANDLING (PERSONNEL) SECTIONS BEFORE PROCEEDING W/CLEAN-UP.
USE APPROPRIATE PERSONNAL PROT EQUIP DURING CLEAN-UP. SPILL CLEAN UP:
DISCARDED MATL IS A RCRA HAZ WASTE. NEUTRALIZE W/LIME/SODA ASH. ACCIDENTAL
RELEASE MEASURES. EVACUATE AREA; KEEP UPWIND UNTIL GAS HAS DISPERSED. WEAR
NIOSH APPROV SCBA IF NEC TO ENTER SPILL AREA. (SUPDAT)
Neutralizing Agent: WASHING WITH LIME OR SODA ASH.
Waste Disposal Methods: COMPLY WITH FEDERAL, STATE, AND LOCAL REGULATIONS. IF
APPROVED, DRAIN NEUTRALIZED WASHINGS TO A WASTE TREATMENT PLANT OR TRANSFER
TO A DISPOSAL CONTRACTOR.
Handling And Storage Precautions: DO NOT BREATHE VAPOR. DO NOT GET IN EYES, ON
SKIN, OR ON CLOTHING. KEEP CONTAINER CLOSED. KEEP AWAY FROM HEAT, SPARKS AND
FLAME. LOOSEN CLOSURES CAREFULLY. NEVER USE PRESSURE TO EMPTY. CONTAINERS
MUST NOT BE WASHED OUT OR USED FOR OTHER PURPOSES.
Other Precautions: DO NOT STORE NEAR ORGANIC OR OTHER READILY OXIDIZABLE
MATERIALS, METAL POWDERS, CYANIDES, SULFIDES, OR CARBIDES.

Fire and Explosion Hazard Information
=======================================================
Flash Point Text: SUPDAT
Extinguishing Media: WATER, DRY CHEMICAL, OR SODA ASH. USE WATER SPRAY TO
COOL CONTAINERS AND REDUCE VAPORS.
Fire Fighting Procedures: WEAR NIOSH APPROVED SCBA & FULL PROTECTIVE
EQUIPMENT (FP N). EVACUATE AREA AND STAY UPWIND. RUNOFF FROM FIRE CONTROL
MAY CAUSE POLLUTION. (SEE DISPOSAL INFORMATION SECTION).
Unusual Fire/Explosion Hazard: NITRIC ACID INCREASES THE FLAMMABILITY OF, AND
CAN IGNITE MANY ORGANIC MATERIALS SUCH AS WOOD, SOLVENTS, ETC., AND CAN
RELEASE TOXIC OXIDES OF NITROGEN. SPILLAGE MAY CAUSE FIRE.
=======================================================
Control Measures
=======================================================
Respiratory Protection: NIOSH APPROVED PERMISSIBLE RESPIRATORY PROTECTION. DO
NOT USE CHEMICAL CARTRIDGE RESPIRATORS WITH OXIDIZABLE SORBANTS.
Ventilation: SUFFICIENT VENTILATION SHOULD BE PROVIDED TO KEEP VAPOR
CONCENTRATIONS BELOW THE EXPOSURE LIMITS.
Protective Gloves: NEOPRENE OR PVC GAUNTLET GLOVES.
Eye Protection: ANSI APPROVED CHEMICAL WORKERS GOGGLES AND FULL LENGTH
FACESHIELD(FP N).
Other Protective Equipment: ANSI APPROVED EMERGENCY EYEWASH AND DELUGE SHOWER
(FP N). APRON & BOOTS; HARD HAT; LONG SLEEVE WOOD, ACRYLIC/POLYESTER CLTHG;
ACID SUIT W/HOOD. IN CASE OF EMER/STRONG POSS OF (ECOL INFO)
Work Hygienic Practices: WASH THOROUGHLY AFTER HANDLING.
Supplemental Safety and Health: SPILL PROC: DIKE LARGE SPILLS. FLUSH WITH
PLENTY OF WATER APPLIED TO ENTIRE SPILL AREA. NEUTRALIZE WASHING WITH LIME OR
SODA ASH. DO NOT FLUSH TO SEWER BEFORE NEUTRALIZING. COMPLY WITH FEDERAL,
STATE, AND LOCAL REGULATIONS ON REPORTING RELEASES. FL PT: NONFLAMMABLE BUT
CAN IGNITE SOME COMBUSTIBLE MATERIALS.
