Potential Health Effects
----------------------------------
Concentrated nitric acid is extremely hazardous; it is corrosive,
reactive, an oxidizer, and a poison. The following hazards are for
concentrated solutions. Hazards of less concentrated solutions may be reduced.
Degree of hazard for reduced concentrations is not currently addressed in the
available literature.
Inhalation:
Corrosive. Effects should
be less severe than from exposure to higher concentrations where symptoms may
include irritation of the nose and throat, labored breathing, as well as lung
edema, damage to the mucous membranes and upper respiratory tract.
Ingestion:
Corrosive. Effects should be less severe than from
exposure to higher concentrations where symptoms may include severe burns of
the mouth, throat, and stomach, leading to death.
Skin Contact:
Corrosive. Effects should be less severe than from exposure to higher
concentrations where symptoms may include redness, pain, and burns to the
skin.
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 or
eye problems or impaired respiratory function may be more susceptible to the
effects of the substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE
VOMITING. Give large quantities of water. Never give anything by mouth to an
unconscious person. Get medical attention immediately.
Skin
Contact:
Immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Get medical attention
immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse.
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 considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
If involved in a fire, use water
spray.
Special Information:
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
absorb with an inert material (e. g., vermiculite, dry sand, earth), and place
in a chemical waste container. Do not use combustible materials, such as saw
dust. Do not flush to sewer! US Regulations (CERCLA) require reporting spills
and releases to soil, water and air in excess of reportable quantities. The
toll free number for the US Coast Guard National Response Center is (800)
424-8802.
J. T. Baker NEUTRASORB(R) or TEAM(R) 'Low Na+' acid
neutralizers are recommended for spills of this product.
7. Handling and Storage
Store in a cool, dry, ventilated storage area with acid resistant
floors and good drainage. Protect from physical damage. Keep out of direct
sunlight and away from heat, water, and incompatible materials. Do not wash
out container and use it for other purposes. When diluting, the acid should
always be added slowly to water and in small amounts. 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):
Not expected to require personal
respirator usage. 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:
Rubber or neoprene gloves and additional
protection including impervious boots, apron, or coveralls, as needed in areas
of unusual exposure 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.

disposal requirements. Processing, use or contamination of this product may
change the waste management options. State and local disposal regulations may
differ from federal disposal regulations. Dispose of container and unused
contents in accordance with federal, state and local requirements.
