Section 3 - Hazards Identification

EMERGENCY OVERVIEW

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 membranes.


Potential Health Effects
Eye: Causes eye burns. May cause permanent corneal opacification.
Skin: Causes skin burns. May be harmful if absorbed through the skin.
Ingestion: 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.
Inhalation: May cause severe irritation of the respiratory tract with possible burns. Exposure may lead to bronchitis, pharyngitis, and dental erosion.
Chronic: 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


Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately.
Skin: 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.
Ingestion: 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.
Inhalation: 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


General Information: 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.
Extinguishing Media: 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.
Flash Point: > 141e deg F (> 60.56 deg C)
Autoignition Temperature: 961 deg F ( 516.11 deg C)
Explosion Limits, Lower:4.0%
Upper: 19.9%
NFPA Rating: (estimated) Health: 3; Flammability: 1; Instability: 0

Section 6 - Accidental Release Measures


General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: 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


Handling: 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.
Storage: 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


Engineering Controls: 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.

Environmental: 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.
Physical: 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.
Other: 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.
