Section 3 - Hazards Identification

Appearance: colorless or white solid.
Danger! Poison! May be fatal if absorbed through the skin. Causes burns by all exposure routes. Harmful if inhaled or swallowed. Corrosive to metal. Hygroscopic (absorbs moisture from the air). Before using this product, make sure that personal protective equipment and engineering controls are used and operating, and also that first aid treatments and procedures are available and understood.
Target Organs: Kidneys, heart, central nervous system, liver, lungs, respiratory system, eyes, skin.


Potential Health Effects
Eye: Causes eye burns.
Skin: May be fatal if absorbed through the skin. Causes skin burns. Substance is rapidly absorbed through the skin. Not expected to cause an allergic skin reaction. In an accident, about 10% of a 24-year-old employee's skin surface was exposed to warm, liquid MCAA. Prompt & thorough washing with water for about 1 hour seemed to remove the soluble salt. Skin burns were considered first degree. The victim's condition suddenly worsened while under observation at the plant dispensary, & he was transported to the hospital. On the journey there, he began to convulse; he died within 10-11 hours of the accident. The autopsy showed congestion, hemorrhage, & confluent petechia of the heart, lungs, & thymus. (Doc of TLV)
Ingestion: Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation: Harmful if inhaled. May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation. Can produce delayed pulmonary edema.
Chronic: May cause liver and kidney damage. Effects may be delayed. May cause lung damage.

Section 4 - First Aid Measures

Eyes: Get medical aid immediately. Extensive irrigation with water is requi red (at least 30 minutes).
Skin: POISON material. In case of contact, get medical aid immediately. Immediately flush eyes or skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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: Chloroacetic acid causes competitive inhibition of acetate oxidation and acetylates sulfhydryl residues in the liver and kidney.
Antidote: Timely administration of intravenous sodium dichloroacetate (SDCA) may be life saving in cases of serious monochloroacetate intoxication. SDCA is not approved for medical use in the United States. Treatment is symptomatic and supportive without it.

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.
Extinguishing Media: Use water spray, dry chemical, "alcohol resistant" foam, or carbon dioxide.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Avoid generating dusty conditions. Provide ventilation. Evacuate unnecessary personnel. Carefully neutralize the dilute spill with lime slurry, soda ash, limestone, caustic soda or other alkaline material. Ensure clean-up is conducted by trained personnel only.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Do not breathe dust, mist, or vapor. Do not get in eyes, on skin, or on clothing. Container should be opened by a technically qualified person. 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. Poison room locked. Do not store in metal containers. Do not store near alkaline substances. Store protected from moisture.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
