**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Reacts violently with water. Causes burns.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract.
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.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Get medical aid. Do NOT allow victim to rub eyes or keep eyes
closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Wash clothing before reuse. Destroy
contaminated shoes. If water-reactive products are embedded in the
skin, no water should be applied. The embedded products should be
covered with a light oil.
Ingestion:
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:

**** 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. Water
Reactive. Material will react with water and may release a flammable
and/or toxic gas. Use water spray to keep fire-exposed containers
cool. May ignite or explode on contact with steam or moist air.
Combustible liquid and vapor.
Extinguishing Media:
Use dry sand or earth to smother fire. Do NOT get water inside
containers.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Forms smooth, slippery surfaces on
floors, posing an accident risk. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. Do
not expose spill to water.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Use with adequate ventilation. Ground and bond containers when
transferring material. Do not get in eyes, on skin, or on clothing.
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep container tightly closed. Keep away from heat,
sparks and flame. Do not allow contact with water. Discard
contaminated shoes. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames. Keep from contact with moist air and steam. Do not breathe
vapor or mist. Product evolves acetic acid when exposed to water or
humid air.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from water. Corrosives area.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower.
Exposure Limits
CAS# 4130-08-9:


Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.

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 respirator use.
