**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes severe burns. Contact with combustible material may cause
fire.
Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Exposure of the skin to the liquid or concentrated vapor produces
severe and penetrating burns. Concentrated nitric acid dyes human
skin yellow on contact.
Ingestion:
Causes gastrointestinal tract burns. May cause perforation of the
digestive tract.
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. May cause acute pulmonary edema, asphyxia, chemical
pneumonitis, and upper airway obstruction caused by edema.
Chronic:
Exposure to high concentrations of nitric acid vapor may cause
pneuomonitis and pulmonary edema which may be fatal. Symptoms may or
may not be delayed. Continued exposure to the vapor & mist of nitric
acid may result in a chronic bronchitis, & more severe exposure
results in a chemical pneumonitis. The vapor & mists of nitric acid
may erode the teeth, particularly affecting the canines & incisors.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General 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 other material may
cause fire. Use water spray to keep fire-exposed containers cool.
Vapors may accumulate in confined spaces Contact with metals may
evolve flammable hydrogen gas. Approach fire from upwind to avoid
hazardous vapors and toxic decomposition products.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Do NOT use straight streams of water.
Cool containers with flooding quantities of water until well after
fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill using an absorbent, non-combustible material such as
earth, sand, or vermiculite. Do not use combustible materials such
as sawdust. Provide ventilation. Evacuate unnecessary personnel.
Approach spill from upwind. Use water spray to cool and disperse
vapors and protect personnel.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Keep
from contact with clothing and other combustible materials. Discard
contaminated shoes. Do not use with metal spatula or other metal
items. Do not breathe vapor or mist. Use only with adequate
ventilation or respiratory protection. Always add the acid to water,
never the reverse.
Storage:
Do not store near combustible materials. Do not store in direct
sunlight. Keep container closed when not in use. Store in a cool,
dry, well-ventilated area away from incompatible substances. Keep
away from metals. Store away from alkalies. Bottles should be vented
periodically in order to overcome pressure buildup. Separate from
organic materials. Avoid storage on wood floors. Shelves and floor
material should be non-combustible and acid-resistant. Inspect
periodically for damage or evidence of leaks or corrosion. This
material may darken during storage due to photochemical reactions.
Keep this bottle in a cool place and remove cap carefully to avoid
spurting.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits. Use a corrosion-resistant ventilation
system.
