Section 3 - Hazards
Appearance: clear to yellow. Danger! Corrosive. Strong
oxidizer. Contact with other material may cause a fire. Causes eye and skin
burns. May cause severe respiratory tract irritation with possible burns. May
cause severe digestive tract irritation with possible burns. May cause severe
digestive tract irritation with possible burns.
Eyes, skin, mucous membranes.
Eye: Causes severe eye burns. May
cause irreversible eye injury. May cause chemical conjunctivitis and corneal
Skin: Causes skin burns. May cause deep,
penetrating ulcers of the skin. May cause skin rash (in milder cases), and cold
and clammy skin with cyanosis or pale color.
cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive tract. May
cause systemic effects.
Inhalation: Effects may be delayed.
Causes chemical burns to the respiratory tract. Inhalation may be fatal as a
result of spasm, inflammation, edema of the larynx and bronchi, chemical
pneumonitis and pulmonary edema. Aspiration may lead to pulmonary edema. May
cause systemic effects. May cause acute pulmonary edema, asphyxia, chemical
pneumonitis, and upper airway obstruction caused by edema.
Chronic: Repeated inhalation may cause chronic bronchitis.
Repeated exposure may cause erosion of teeth. Effects may be delayed.
Section 4 - First Aid
Eyes: Get medical aid immediately. Do NOT allow
victim to rub or keep eyes closed. Extensive irrigation with water is required
(at least 30 minutes).
Skin: Get medical aid immediately.
Immediately flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before reuse.
Destroy contaminated shoes.
Ingestion: Do NOT induce
vomiting. 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
Inhalation: Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration using oxygen
and a suitable mechanical device such as a bag and a mask.
Physician: Treat symptomatically and supportively.
Section 5 - Fire
Information: As in any fire, wear a self-contained breathing apparatus
in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective
gear. Strong oxidizer. Contact with combustible materials may cause a fire.
During a fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Use water spray to keep fire-exposed containers
cool. Substance is noncombustible. Use water with caution and in flooding
Extinguishing Media: Substance is noncombustible;
use agent most appropriate to extinguish surrounding fire. Contact professional
Section 6 -
Accidental Release Measures
Information: Use proper personal protective equipment as indicated in
Spills/Leaks: Absorb spill with inert material
(e.g. vermiculite, sand or earth), then place in suitable container. Avoid
runoff into storm sewers and ditches which lead to waterways. Clean up spills
immediately, observing precautions in the Protective Equipment section.
Neutralize spill with sodium bicarbonate. Provide ventilation. A vapor
suppressing foam may be used to reduce vapors.
Section 7 - Handling
Handling: Wash thoroughly after handling. Remove
contaminated clothing and wash before reuse. Use only in a well-ventilated area.
Do not breathe dust, vapor, mist, or gas. Keep container tightly closed. Avoid
contact with clothing and other combustible materials. Do not get on skin or in
eyes. Avoid ingestion and inhalation. Discard contaminated shoes.
Storage: Keep away from heat, sparks, and flame. Do not
store near combustible materials. Keep container closed when not in use. Store
in a cool, dry, well-ventilated area away from incompatible substances.
Section 8 - Exposure
Controls, Personal Protection
Controls: Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower. Use adequate ventilation
to keep airborne concentrations low.

During transport through the soil, nitric acid will dissolve some of the soil
material, in particular, the carbonate based materials. The acid will be
neutralized to some degree with adsorption of the proton also occurring on clay
materials. However, significant amounts of acid are expected to remain for
transport down toward the ground water table. Upon reaching the ground water
table, the acid will continue to move, now in the direction of the ground water
Physical: Not expected to biodegrade or bioconcentrate.
