General Description
Colorless to yellow liquid with an odor of chloroform. Sinks in water. Produces irritating vapor. (USCG, 1999)
Hazards
Reactivity Alerts
- Highly Flammable
- Polymerizable
Air & Water Reactions
Highly flammable. Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Highly toxic vapors.
Behavior in Fire: Emits highly toxic vapors. (USCG, 1999)
Health Hazard
INHALATION: Vapors are poisonous, painful and irritating. Headache and dizziness may occur. Overexposure may cause liver and kidney damage and even death. EYES: Irritation and lacrimation. May cause transient corneal injury. SKIN: Slight irritation, readily absorbed in toxic amounts causing headache and dizziness and other systematic symptoms. INGESTION: Acute gastrointestinal distress with pulmonary congestion and edema. CNS Depression. (USCG, 1999)

Response Recommendations
Isolation and Evacuation
Excerpt from 129
[Flammable Liquids (Water-Miscible / Noxious)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Fire Extinguishing Agents Not to Be Used: None noted.
Fire Extinguishing Agents: Small fires: dry chemical or CO2. Large fires: water fog or spray, or foam. (USCG, 1999)
Non-Fire Response
SMALL SPILLS AND LEAKAGE: If you should spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
STORAGE PRECAUTIONS: You should store this chemical in an explosion-proof refrigerator and keep it away from oxidizing materials. STORE AWAY FROM SOURCES OF IGNITION. (NTP, 1992)
Protective Clothing
Rubber gloves, self-contained breathing apparatus, protective clothing. (USCG, 1999)

First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
INGESTION: DO NOT INDUCE VOMITING. Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
