[Safety Profile]

Poison by ingestion, inhalation, and intraperitoneal routes. Moderately toxic by skin contact. Human systemic effects by inhalation: conjunctiva irritation and respiratory effects. Corrosive to skin, eyes, and mucous membranes. Very dangerous fire hazard when exposed to heat sources, sparks, flame, or oxidzers. Reacts with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits toxic fumes of Cl-, methyl chloroformate, and phosgene.

Hazard InformationBack Directory
[General Description]

A colorless liquid with a pungent odor. Flash point 54°F. Corrosive to metals and tissue. Vapors heavier than air. Very toxic by inhalation. Used to make other chemicals and insecticides.
[Reactivity Profile]

METHYL CHLOROFORMATE(79-22-1) is incompatible with water, strong oxidizing agents, alcohols, bases (including amines). Decomposes slowly in water to yield methanol, HCl, and CO2; reaction can be hazardous if water is hot. Attacks many metals especially in humid atmosphere [Handling Chemicals Safely 1980. p. 476]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
[Air & Water Reactions]

Highly flammable. Gives off hydrochloric acid fumes in contact with moist air. Slightly soluble in water and decomposed by water to hydrochloric acid with evolution of heat.
[Hazard]

Flammable, dangerous fire risk. Highly corrosive and irritant to skin and eyes.
[Health Hazard]

Methyl chloroformate is highly toxic upon inhalation and upon ingestion. A concentration of 1 mg/liter (190 ppm) has been lethal in 10 minutes. It is corrosive and irritating to skin.
[Potential Exposure]

Used in synthesis of pharmaceuticals; herbicides, plastics and other organic chemicals; as a solvent in the photographic industry; as a chemical intermediate in the production of other chemicals. In WWI it was used as military tear-producing warfare agent.
[Fire Hazard]

This chemical is very dangerous when exposed to heat sources, sparks, flame, or oxidizers. METHYL CHLOROFORMATE will react with water or steam to produce toxic and corrosive fumes. Vapors may travel to a source of ignition and flash back. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire. Toxic fumes of phosgene are produced when the material is heated to decomposition. Heat or steam should be avoided.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 30 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
[Shipping]

UN1238 Methyl chloroformate, Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard, 3-Flammable liquid, 8-Corrosive material Inhalation Hazard Zone A
[Incompatibilities]

May form explosive mixture with air. Violent reaction with alkali metals; ethers. Incompatible with strong acids; strong bases; alcohols, oxidizers, dimethylsulfoxide; dimethyl formamide. Contact with water or moisture produces corrosive and poisonous hydrogen chloride gas, methanol and carbon monoxide. Corrodes metals in the presence of moisture. Attacks some plastics, rubber and coatings.
[Waste Disposal]

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal
