**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. Causes severe burns.Corrosive.
Potential Health Effects
Eye:
Causes severe eye irritation. Contact with liquid or vapor causes
severe burns and possible irreversible eye damage.
Skin:
Causes skin burns. May be harmful if absorbed through the skin.
Contact with the skin may cause blackening and hyperkeratosis of the
skin of the hands.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
severe pain, nausea, vomiting, diarrhea, and shock. May cause
polyuria, oliguria (excretion of a diminished amount of urine in
relation to the fluid intake) and anuria (complete suppression of
urination). Rapidly absorbed from the gastrointestinal tract.
Inhalation:
Effects may be delayed. Causes chemical burns to the respiratory
tract. Exposure may lead to bronchitis, pharyngitis, and dental
erosion. May be absorbed through the lungs.
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
at 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:
Persons with pre-existing skin disorders or impaired respiratory or
pulmonary function may be at increased risk to the effects of this
substance. Treat symptomatically and supportively.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Use water spray to keep fire-exposed containers cool. Wear
appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products. Reacts with most metals
to form highly flammable hydrogen gas which can form explosive
mixtures with air. Flammable liquid and vapor. Vapors are heavier
than air and may travel to a source of ignition and flash back.
Vapors can spread along the ground and collect in low or confined
areas.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. For large fires, use water spray, fog or
alcohol-resistant foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Use water spray to dilute spill to a non-flammable mixture. Avoid
runoff into storm sewers and ditches which lead to waterways. Wash
area with soap and water. Use water spray to disperse the gas/vapor.
Remove all sources of ignition. Use a spark-proof tool. Provide
ventilation. Cover with material such as dry soda ash or calcium
carbonate and place into a closed container for disposal. A vapor
suppressing foam may be used to reduce vapors. U.S. regulations
require reporting spills and releases to soil, water and air in
excess of reportable quantities.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep away from heat, sparks and flame. Do not ingest or
inhale. Discard contaminated shoes. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Use only with adequate ventilation.
Storage:
Keep away from heat, sparks, and flame. Keep from freezing. Keep
from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
near alkaline substances. Acetic acid should be kept above its
freezing point of 62F(17C) to allow it to be handled as a liquid.
It will contract slightly on freezing. Freezing and thawing does not
affect product quality.
**** 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.
Personal Protective Equipment
Eyes:
Wear chemical goggles.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
