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

12. Ecological Information
Environmental Fate:
When released into the air, this
material may be moderately degraded by reaction with photochemically produced
hydroxyl radicals. When released into air, this material is expected to have a
half-life between 10 and 30 days. When released into water, this material is
expected to readily biodegrade. When released into the water, this material is
expected to have a half-life between 1 and 10 days. Standard dilution BOD5/TOD
= 58% When released into the soil, this material is expected to readily
biodegrade. This material is not expected to significantly bioaccumulate. This
material has an estimated bioconcentration factor (BCF) of less than 100.
Environmental Toxicity:
This material is expected to be
slightly toxic to aquatic life. The LC50/96-hour values for fish are between
10 and 100 mg/l.
For glacial acetic acid:
EC50 (wheat fumigation)
= 23.3 mg/m3/2-hr, effect: leaf injury
LC50 (shrimp) = 100 - 300
mg/l/48-hr
LC50 (fathead minnow) = 88 mg/l/96-hr
This material may be
toxic to aquatic life.
13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be
handled as hazardous waste and sent to a RCRA approved waste facility.
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.
