Section 3. Hazard Identification
Emergency Overview: Corrosive. May cause irritation to areas of contact. Wash areas of contact
with water for at least 15 minutes. If ingested, do not induce vomiting. Dilute with
water and call a physician.
Target Organs: Eyes, skin, respiratory system, teeth.
Skin/eye Contact: Liquid may cause burns to skin and eyes.
Inhalation: May cause irritation.
Ingestion: May cause nausea, vomiting, and diarrhea.
Section 4. First Aid Measures
Inhalation: Remove to fresh air. Give artificial respiration if necessary. If breathing is difficult, give
oxygen.
Skin/eye Contact: Remove contaminated shoes and clothing. Flush contaminated area with
plenty of water for at least 15 minutes. Call a physician if irritation develops.
Ingestion: Rinse mouth with water. If swallowed, do NOT induce vomiting, if conscious give
large quantities of water or milk. CALL A PHYSICIAN.
Section 5. Fire Fighting Measures
Fire & Explosion hazards: While nitric acid is not combustible, it is a strong oxidizing agent that
can react with combustible materials. NOx compounds can be released in event of fire.
Extinguishing Media: Use any extinguishing media that is suitable for the surrounding area. Use a
water spray to dilute nitric acid and to absorb liberated nitrogen oxides.
Specific Methods: Firefighters should wear proper protective equipment and self-contained
breathing apparatus with full face piece operated in positive pressure mode.

Section 6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in
Section 8. Cover the spill with sodium bicarbonate or a soda ash-slaked lime mixture (50:50) to
neutralize the acid. Place the neutralized material into containers suitable for eventual disposal,
reclamation, or destruction. Always dispose of in accordance with local regulations.
Section 7. Handling and Storage
Store in a cool, dry, ventilated storage area with acid resistant floors and good drainage. Keep out
of direct sunlight and away from heat, water, and incompatible materials. When diluting, the acid
should always be added slowly to water and in small amounts. Refer to Section 8 for personal
handling instructions.
Section 8. Exposure Controls and Personal Protection
Engineering Controls: No specific controls are needed. Normal room ventilation is adequate.
Respiratory Protection: Normal room ventilation is adequate.
Personal Protection: Wear proper gloves, safety glasses with side shields, lab coat/apron.
