Substance: 2-Chloroethyl Vinyl Ether
Purity: ≥ 99%
Impurities Contributing to Hazard: None significant
Inhalation: Remove victim to fresh air without delay. Seek medical attention if breathing is difficult or symptoms persist.
Skin Contact: Remove contaminated clothing. Wash skin immediately with plenty of water and soap for at least 15 minutes. Get medical help for irritation or persistent symptoms.
Eye Contact: Rinse eyes cautiously with plenty of water for several minutes. Remove contact lenses if safe to do so. Contact physician.
Ingestion: Rinse mouth. Do not induce vomiting. Immediately seek medical help. Never provide anything by mouth to an unconscious person.
Acute Symptoms: May cause burns, irritation, nausea, headaches, respiratory distress, central nervous system depression.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Water jet can spread fire
Special Hazards: Vapors form explosive mixtures with air, can travel to ignition source, combustion may produce toxic gases such as hydrogen chloride and phosgene
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus (SCBA)
Advice for Firefighters: Move containers from fire area if safe. Cool exposed containers with water spray. Avoid breathing vapors or decomposition products.
Personal Precautions: Evacuate personnel to safe area. Remove all sources of ignition. Ventilate area. Wear chemical-resistant gloves, protective clothing, and eye protection.
Environmental Precautions: Prevent further leakage or spillage. Stop spill from reaching drains, soil, or water bodies.
Methods for Containment: Absorb spills with inert material such as dry sand or earth. Shovel into suitable container for disposal.
Cleaning Up Procedures: Wash spill site once clean-up is complete. Ensure proper ventilation.
Handling: Only use in a chemical fume hood or well-ventilated area. Keep away from flames, sparks, and heat. Wear all recommended personal protective equipment. Avoid breathing vapor or mist. Avoid skin and eye contact.
Storage: Store in cool, tightly closed containers in a dry, well-ventilated location. Separate from oxidizers, acids, and water. Keep locked up and label clearly.
Incompatible Materials: Strong acids, oxidizing agents, strong bases, amines
Permissible Exposure Limits (OSHA): No specific limit set, but minimize exposure as much as possible
Engineering Controls: Use local exhaust ventilation. Ensure safety shower and eyewash stations are available.
Personal Protection: Chemical-resistant gloves (nitrile or butyl rubber), safety goggles, face shield, lab coat or apron
