Potential Health Effects
----------------------------------
Nitric acid is extremely hazardous; it is corrosive, reactive, an oxidizer,
and a poison.
Inhalation:
Corrosive! Inhalation of vapors can cause breathing difficulties and lead
to pneumonia and pulmonary edema, which may be fatal. Other symptoms may
include coughing, choking, and irritation of the nose, throat, and
respiratory tract.
Ingestion:
Corrosive! Swallowing nitric acid can cause immediate pain and burns of the
mouth, throat, esophagus and gastrointestinal tract.
Skin Contact:
Corrosive! Can cause redness, pain, and severe skin burns. Concentrated
solutions cause deep ulcers and stain skin a yellow or yellow-brown color.
Eye Contact:
Corrosive! Vapors are irritating and may cause damage to the eyes. Contact
may cause severe burns and permanent eye damage.
Chronic Exposure:
Long-term exposure to concentrated vapors may cause erosion of teeth and
lung damage. Long-term exposures seldom occur due to the corrosive
properties of the acid.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders, eye disease, or cardiopulmonary
diseases may be more susceptible to the effects of this substance.
4. First Aid Measures
Immediate first aid treatment reduces the health effects of this substance.
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
Ingestion:
DO NOT INDUCE VOMITING! Give large quantities of water or milk if
available. Never give anything by mouth to an unconscious person. Get
medical attention immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes. Wash
clothing before reuse. Thoroughly clean shoes before reuse. Get medical
attention immediately.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition. Can react with metals to release flammable hydrogen gas.
Explosion:
May react explosively with combustible organic or readily oxidizable
materials such as: alcohols, turpentine, charcoal, organic refuse, metal
powder, hydrogen sulfide, etc.
Fire Extinguishing Media:
If involved in a fire, use water spray.
Special Information:
Increases the flammability of combustible, organic and readily oxidizable
materials. In the event of a fire, wear full protective clothing and
NIOSH-approved self-contained breathing apparatus with full facepiece
operated in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Isolate hazard area. Keep unnecessary
and unprotected personnel from entering. Contain and recover liquid when
possible. Neutralize with alkaline material (soda ash, lime), then absre recommended for spills of this product.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect from physical damage and direct sunlight. Isolate from incompatible
substances. Containers of this material may be hazardous when empty since
they retain product residues (vapors, liquid); observe all warnings and
precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
For Nitric Acid:
OSHA Permissible Exposure Limit (PEL):
2 ppm (TWA)
ACGIH Threshold Limit Value (TLV):
2 ppm (TWA); 4 ppm (STEL)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is
generally preferred because it can control the emissions of the contaminant
at its source, preventing dispersion of it into the general work area.
Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, wear a supplied air, full-facepiece
respirator, airlined hood, or full-facepiece self-contained breathing
apparatus. Nitric acid is an oxidizer and should not come in contact with
cartridges and canisters that contain oxidizable materials, such as
activated charcoal. Canister-type respirators using sorbents are
ineffective.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work
area.
