Material Safety Data Sheet
SECTION IV - FIRE AND EXPLOSION HAZARD DATA
Flash Point: Not Applicable Flammable Limits: Not Applicable
Extinguishing Media: Water
Special Fire Fighting Procedures: Soak with water. Use water spray to cool containers and reduce and knock down
vapors. Apply water from as far away as possible and avoid directing water into the acid. Neutralize small amounts of
spilled acid with crushed limestone, soda ash or lime. Wear self-contained breathing apparatus and full fire-fighting
protective gear.
Unusual Fire and Explosion Hazards: Will emit oxides of nitrogen upon heating. Strong oxidizer. May cause
spontaneous combustion when in contact with organic or combustible materials. Reacts vigorously with water to liberate
heat, fumes of nitric acid or nitrogen oxides.
SECTION V - HEALTH HAZARD DATA
Effects of Overexposure
Eyes: Will produce severe, immediate damage and may result in permanent damage or loss.
Skin: Will produce immediate, penetrating chemical burns, with a characteristic yellow coloration. Severe and fatal skin
burns can occur with necrosis and scarring.
Ingestion: Will cause immediate irritation, chemical burns to mouth and throat, and may cause hemorrhaging, necrosis
and perforation of the gastrointestinal tract. Based on toxicity data for other acids, not expected to be toxic by oral
exposure as defined by OSHA.
Inhalation: Highly toxic by inhalation as defined by OSHA. Mild exposure may cause irritation and burning of the nose
and throat. Extreme inhalation may cause difficult breathing, loss of consciousness, pulmonary edema or death. Lung
damage may appear after a delay of up to 48 hours after exposure.
Emergency and First Aid Procedures
Eyes: Irrigate with running water for at least fifteen minutes. Seek immediate medical attention.
Skin: Immediately remove contaminated clothing. Flush with running stream of water for at least fifteen minutes. Wash
with soap. Seek medical attention.
Ingestion: Do not induce vomiting. Drink three or more glasses of water or milk to dilute acid. Seek immediate
medical attention.
Inhalation: Remove from exposure immediately. Restore or support respiration. Seek immediate medical attention for
unprotected exposures beyond exposure limits.
Special Considerations: If exposure to Nitric Acid vapor occurs, medical observation should continue for 24 - 48 hours
after exposure. Delayed reactions may cause pulmonary edema.
SECTION VI - REACTIVITY DATA
Stability: Stable under normal conditions.
Conditions to Avoid: Avoid exposure to sunlight, which promotes oxide formation.
Materials to Avoid (Incompatibility): Bases. Organic and combustible materials. Will corrode most metals. Beware of
containers, pumps, and hoses of inadequate construction and/or contamination by incompatible materials.
Hazardous Decomposition Products: Nitrogen Oxides (NOx)
Hazardous Polymerization: Will not occur.

Material Safety Data Sheet
SECTION VII - SPILL OR LEAK PROCEDURES
Steps to be taken in Case Material is Released or Spilled: Evacuate unnecessary personnel to safe area upwind of
spill. Nitric acid vapor is denser than air and will concentrate in low spots. If necessary to enter spill area, wear full
protective clothing including boots and proper breathing apparatus. Dike large spills and pump to salvage. If not possible
to salvage, neutralize with soda ash or lime. If possible, carefully dilute the acid or the neutralizing material with water to
slow down exceedingly vigorous neutralization reactions. Water spray can be used to reduce and knock down the vapors.
Apply water from as far away as possible and avoid directing it into the acid. Do not get water in salvage containers since
a violent reaction may occur. Notify authorities in accordance with emergency response procedures. Only personnel
trained in emergency response should respond. Follow Federal, State, and local spill reporting requirements.
Waste Disposal Method: Disposal must comply with Federal, State and local regulations. If product becomes
a waste, it is potentially regulated as a hazardous waste as defined under the Resource Conservation and Recovery
Act (RCRA) 40 CFR, part 261. Review disposal requirements with a person knowledgeable with applicable environmental
law (RCRA) before disposing of any hazardous material.
SECTION VIII - SPECIAL PROTECTION INFORMATION
Ventilation: Mechanical ventilation and/or local exhaust is recommended where needed to meet TLV requirement.
Respiratory Protection: For concentrations above the exposure limits, use full face supplied air respirator approved by
NIOSH for nitric acid or nitrogen oxide gases or mists. Chemical cartridge or canister respirators are not suitable for
nitric acid or nitrogen oxide use.
Protective Clothing: Neoprene or PVC gloves are required. Where spill or splash potential exists, rubberized aprons or
chemical resistant suits are strongly recommended.
Eye Protection: Acid proof goggles and face shield should be required where acid is transferred, sampled, or where
persons are otherwise potentially exposed. Eye baths should be provided when direct contact is possible.
Other Precautions Required: Provide safety showers and eyewash in immediate vicinity.
SECTION IX - SPECIAL PRECAUTIONS
Precautions to be Taken in Handling and Storage: Store in clean, cool, well-ventilated area away from organic
chemicals, bases, and metal powders.
Other Precautions: Avoid hydrocarbon lubricants and packing materials. Corrosion-resistant materials, such as stainless
steel, must be used.
