Potential Health Effects
----------------------------------
Inhalation:
Inhalation of concentrated vapors may cause serious damage to the lining of
the nose, throat, and lungs. Breathing difficulties may occur. Neither odor
nor degree of irritation are adequate to indicate vapor concentration.
Ingestion:
Swallowing can cause severe injury leading to death. Symptoms include sore
throat, vomiting, and diarrhea. Ingestion of as little as 1.0 ml has
resulted in perforation of the esophagus.
Skin Contact:
Contact with concentrated solution may cause serious damage to the skin.
Effects may include redness, pain, skin burns. High vapor concentrations
may cause skin sensitization.
Eye Contact:
Eye contact with concentrated solutions may cause severe eye damage
followed by loss of sight. Exposure to vapor may cause intense watering and
irritation to eyes.
Chronic Exposure:
Repeated or prolonged exposures may cause darkening of the skin, erosion of
exposed front teeth, and chronic inflammation of the nose, throat, and
bronchial tubes.
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. 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. Call a physician.
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:
Flash point: 40C (104F) CC
Autoignition temperature: 427C (801F)
Flammable limits in air % by volume:
lel: 4.0; uel: 16.0
Flammable Liquid and Vapor!
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Vapors can flow along surfaces to distant ignition source and
flash back. Contact with strong oxidizers may cause fire. Reacts with most
metals to produce hydrogen gas, which can form an explosive mixture with
air.
Fire Extinguishing Media:
Water, dry chemical, foam or carbon dioxide. Water spray may be used to
keep fire exposed containers cool.
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. Water may be used to flush
spills away from exposures and to dilute spills to non-flammable mixtures.
Water diluted acid can react with metals to form hydrogen gas.
6. Accidental Release Measures
Ventilate area of leak or spill. Remove all sources of ignition. Wear
appropriate personal protective equipment as specified in Section 8.
Isolate hazard area. Keep unnecessary and unprotected personnel from
entering. Use water spray to dilute spill to a nonflammable mixture.
Contain and recover liquid when possible. Collect liquid in an appropriate
container or absorb with an inert material (e. g., vermiculite, dry sand,
earth), and place in a chemical waste container. Use non-sparking tools and
equipment. 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
Protect against physical damage. Store in a cool, dry well-ventilated
location, away from any area where the fire hazard may be acute. Outside or
detached storage is preferred. Separate from incompatibles. Containers
should be bonded and grounded for transfers to avoid static sparks. Storage
and use areas should be No Smoking areas. Use non-sparking type tools and
equipment, including explosion proof ventilation. Protect from freezing.
Store above 17C (63F). 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:
-OSHA Permissible Exposure Limit (PEL):
10 ppm (TWA).
-ACGIH Threshold Limit Value (TLV):
10 ppm (TWA); 15 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, a full facepiece respirator with organic
vapor cartridge may be worn up to 50 times the exposure limit or the
maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. For emergencies or instances
where the exposure levels are not known, use a full-facepiece
positive-pressure, air-supplied respirator. WARNING: Air purifying
respirators do not protect workers in oxygen-deficient atmospheres.
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.

contribute to instability. Releases heat and toxic, irritating vapors when
mixed with water. Acetic acid contracts slightly upon freezing which may
cause the container to burst.

Carbon dioxide and carbon monoxide may form when heated to decomposition.
May also release toxic and irritating vapors.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Acetic Acid is incompatible with chromic acid, nitric acid, ethylene
glycol, perchloric acid, phosphorous trichloride, oxidizers, sodium
peroxide, strong caustics, most metals (except aluminum), carbonates,
hydroxides, oxides, and phosphates.
