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

EMERGENCY OVERVIEW
Toxic if swallowed. Causes burns. Very toxic to aquatic
organisms.Corrosive.

Potential Health Effects
Eye:
May cause irreversible eye injury. Contact with liquid is
corrosive to the eyes and causes severe burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
May cause perforation of the digestive tract. Causes severe
digestive tract burns with abdominal pain, vomiting, and possible
death. May cause corrosion and permanent tissue destruction of the
esophagus and digestive tract. May be harmful if swallowed.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause liver and kidney damage. Causes severe irritation
of upper respiratory tract with coughing, burns, breathing
difficulty, and possible coma. May cause pulmonary edema and severe
respiratory disturbances. May cause kidney damage.
Chronic:
May cause liver and kidney damage.

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

Eyes:
Get medical aid immediately. 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. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. 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:
Chloroacetic acid causes competitive inhibition of acetate oxidation
and acetylates sulfhydryl residues in the liver and kidney.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. 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. Contact with metals may evolve flammable
hydrogen gas. Containers may explode when heated. Combustible
material; may burn but does not ignite readily.
Extinguishing Media:
Water or foam may cause frothing. Use water spray to cool
fire-exposed containers. Do NOT get water inside containers. For
small fires, use dry chemical, carbon dioxide, or water spray. For
large fires, use dry chemical, carbon dioxide, alcohol-resistant
foam, or water spray. 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.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Avoid generating dusty conditions. Remove all
sources of ignition. Provide ventilation. Do not get water inside
containers. Cover with dry earth, dry sand, or other non-combustible
material followed with plastic sheet to minimize spreading and
contact with water.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Keep
container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Discard contaminated shoes.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Keep away from metals. Keep away from
reducing agents. Do not store in metal containers. Do not store near
alkaline substances.

**** 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
ventilation to keep airborne concentrations low.

safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
