3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW: A clear, colorless liquid with a sour, pungent odor resembling
vinegar. Causes severe burns to the skin and eyes. Harmful if inhaled or swallowed.
POTENTIAL HEALTH HAZARDS
SKIN: Concentrated solution causes severe burns if not promptly washed off. Vapor may blacken skin and
exposed teeth. Dilute solutions may cause dermatitis in some sensitive individuals.
EYES: Causes severe burns. May cause permanent corneal injury, which may be followed by blindness. High
vapor concentrations may result in conjunctivitis.

No ingredients listed in this section.
4. FIRST AID MEASURES
SKIN: Immediately flush with plenty of water for 15 minutes, while removing contaminated clothing. Wash clothing
before reuse. Get medical attention.
EYES: Immediately flush eyes with plenty of water for at least 15 minutes. If irritation persists, flush an additional
15 minutes. Get medical attention.
INHALATION: Remove to fresh air. If not breathing, give artificial respiration, preferably mouth-to-mouth. If
breathing is difficult, give oxygen provided a qualified operator is available. Get medical attention.
INGESTION: Do not induce vomiting. Give tap water, milk (2-3 glasses), milk of magnesia or egg whites beaten
with water. Never give anything by mouth to an unconscious person. Get medical attention.
ADVICE TO PHYSICIAN: Treat symptomatically.

MATERIAL SAFETY DATA SHEET
Acetic Acid
SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
Use water spray to cool containers exposed to fire and to protect those involved in firefighting. Involved personnel
should wear self-contained breathing apparatus and eye protection and full protective clothing. Water may be
used to dilute spilled material, to reduce flammability and to dissipate irritating vapors evolving from the fire.
6. ACCIDENTAL RELEASE MEASURES
IN CASE OF SPILL OR OTHER RELEASE: (See section 8 for recommended personal protective equipment.)
Provide adequate ventilation. Clean-up personnel should wear self-contained breathing apparatus and personal
protective equipment to prevent liquid contact. Use water spray to dispense vapors and protect involved
personnel and to reduce flammability. Eliminate ignition sources. Small spills can be neutralized with soda ash or
sodium bicarbonate. Large spills should be contained and collected in covered containers, if possible, and then
labeled for eventual disposal.
Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding
reporting requirements.
7. HANDLING AND STORAGE
NORMAL HANDLING: (See section 8 for recommended personal protective equipment.)
Avoid breathing vapors. Avoid liquid or vapor contact with eyes, skin and clothing. Use with adequate ventilation.
Keep away from heat, sparks and open flame (also, electrical equipment and wiring). Wear personal protective
equipment as needed.
STORAGE RECOMMENDATIONS:
Store in closed containers in a well-ventilated area. Outdoors or detached storage is preferred. Keep away from
oxidizing agents and combustible materials. Keep above its freezing point (62F) to avoid rupture of carboys and
glass containers due to expansion upon solidification. If frozen, thaw by carefully moving container to a warm
area.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS:
Provide adequate exhaust ventilation to meet TLV/TWA requirements. Local exhaust 鈥? from floor and low spaces.
Mechanical (general) 鈥? floor-mounted fan or blower. Material should preferably be used in an exhausted hood.
Equipment should be explosion-proof and exhaust ducts should be acid-resistant.
PERSONAL PROTECTIVE EQUIPMENT
SKIN PROTECTION: Wear impervious gloves (rubber or neoprene) and rubber apron. In case of leak,
spill or emergency situations with possibility of contact with the material, add full
impervious clothing. Rubber boots may be required depending upon working
conditions.

MATERIAL SAFETY DATA SHEET
Acetic Acid
EYE PROTECTION: For material handled normally in a closed ventilated system, wear safety glasses
with nonperforated side shields. For leak, spill or other emergency, wear chemical
safety goggles or full face shield to guard against splashing. Do not wear contact
lenses under these conditions.
RESPIRATORY Where vapors are below 500 ppm, use a NIOSH-approved chemical cartridge,
PROTECTION: organic vapor respirator with full facepiece or a self-contained breathing apparatus
with full facepiece. Vapors to 1000 ppm require a NIOSH-approved air-supplied
respirator with full facepiece. Escape conditions call for NIOSH-approved gas mask
with organic vapor canister or self-contained breathing apparatus.
ADDITIONAL Eyewash stations and safety showers should be provided in areas of use or
RECOMMENDATIONS: handling. Provide protective carriers for handling material in glass bottles.
