Section 3 - Hazards Identification
Appearance: clear colorless liquid. Flash Point: > 141 deg F.
Danger! Corrosive. Causes eye and skin burns. May
be harmful if absorbed through the skin. May cause severe
respiratory tract irritation with possible burns. May cause severe
digestive tract irritation with possible burns.
Target Organs: Teeth, eyes, skin, mucous
Potential Health Effects
Causes eye burns. May cause permanent corneal opacification.
Causes skin burns. May be harmful if absorbed through the skin.
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns. May cause corrosion and permanent
tissue destruction of the esophagus and digestive tract.
May cause severe irritation of the respiratory tract with possible
burns. Exposure may lead to bronchitis, pharyngitis, and dental
Chronic exposure to acetic acid may cause erosion of dental enamel,
bronchitis, eye irritation, darkening of the skin, and chronic
inflammation of the respiratory tract. Acetic acid can cause
occupational asthma. One case of a delayed asthmatic response to
glacial acetic acid has been reported in a person with bronchial
asthma. Skin sensitization to acetic acid is rare, but has occurred.
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas. Contact with metals may evolve flammable
hydrogen gas. Containers may explode when heated.
Do NOT get water inside containers. For large fires, use dry
chemical, carbon dioxide, alcohol-resistant foam, or water spray. For
small fires, use dry chemical, carbon dioxide, water spray or regular
foam. Cool containers with flooding quantities of water until well
after fire is out.

Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Provide
ventilation. Do not get water inside containers.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Do not get in
eyes, on skin, or on clothing. Keep container tightly closed. Do not
ingest or inhale.
Keep away from sources of ignition. Keep container closed when not
in use. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
near alkaline substances. Keep away from oxidizing agents.
Section 8 - Exposure Controls, Personal Protection
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

When spilled on soil, the liquid will spread on the surface and
penetrate into the soil at a rate dependent on the soil type and its
water content.. Natural waters will neutralize dilute solutions to
acetate salts. The dominant environmental fate process for acetic
acid in water is biodegradation. A large number of biological
screening studies have determined that acetic acid biodegrades
readily under aerobic and anaerobic conditions. Aquatic hydrolysis
and bioconcentration are not important.
The experimentally determined rate constant for the vapor-phase
reaction of acetic acid with photochemically produced hydroxyl
radicals has been reported to be 0.6X10-12 cu cm/molecule-sec at 25
deg C; the atmospheric half-life for this reaction can be estimated
to be 26.7 days.
Acetic acid shows no potential for biological accumulation or food
chain contamination. Based on a log Kow of -0.17, the BCF for acetic
acid can be estimated to be <1. This indicates that bioconcentration
is not significant.
Section 13 - Disposal Considerations
Chemical waste generators must determine whether a discarded chemical is classified
as a hazardous waste.
US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
Additionally, waste generators must consult state and local hazardous waste regulations to
ensure complete and accurate classification.
