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.

10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage. Heat and sunlight can
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.
Hazardous Decomposition Products:
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.
Conditions to Avoid:
Heat, flame, ignition sources, freezing, incompatibles
