CHLOROMETHYL ETHYL ETHER tends to form unstable peroxides when exposed to oxygen or air. These products can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid. Forms salts with strong acids and addition complexes with Lewis acids. May react violently with strong oxidizing agents.

Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]: CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam. LARGE FIRE: Water spray, fog or alcohol-resistant foam. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. Use water spray or fog; do not use straight streams. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2016)
Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. 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, 2016)
Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]: Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. SMALL SPILL: Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal. Use clean, non-sparking tools to collect absorbed material. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)
Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.

Toxicity
There are no known natural sources of chloromethyl ethyl ether(1).
Chloromethyl ethyl ether has been listed as a compound with no specific industrial manufacture or use(1). The compound has been listed as a possible byproduct of water chlorination; a probable precursor is methyl ethyl ether(1).
TERRESTRIAL FATE: The fate of chloromethyl ethyl ether in soil is unknown. However, due to its expected rapid hydrolysis rate in water, which is based upon measured hydrolysis rates for the structurally related chloromethyl methyl ether(1), chloromethyl ethyl ether would be expected to disappear rapidly from moist soil. Significant adsorption to soil, therefore, is not expected to occur.|AQUATIC FATE: If released to water, chloromethyl ethyl ether will hydrolyze rapidly based upon the hydrolysis half-life of <1 sec for the structurally related chloromethyl methyl ether in pure water at 20 °C(1). It will not, therefore, be expected to adsorb to sediment or suspended particulates, bioconcentrate in aquatic organisms, biodegrade, or significantly volatilize from water(SRC).|ATMOSPHERIC FATE: If released to the atmosphere, chloromethyl ethyl ether will be subject reaction with photochemically produced hydroxyl radicals with a half-life of 53 hours estimated for this process(1,SRC). It may be susceptible to surface catalyzed(2) hydrolysis in humid air, based upon observed hydrolysis of the structurally related chloromethyl methyl ether in humid air(3).
Hydrolysis of chloromethyl ethyl ether is expected to be very rapid(SRC), based upon the hydrolysis half-life of <1 sec for the structurally related chloromethyl methyl ether in pure water at 20 °C(1). It may be susceptible to surface catalyzed(2) hydrolysis in humid air, based upon observed hydrolysis of the structurally related chloromethyl methyl ether in humid air(1). The rate constant for the vapor phase reaction of chloromethyl ethyl ether with photochemically produced hydroxyl radicals has been estimated to be 7.2X10-12 cu cm/molecule-sec at 25 °C which corresponds to an atmospheric half-life of 53 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(3,SRC).
Based upon the hydrolysis half-life of <1 sec for the structurally related chloromethyl methyl ether in pure water at 20 °C(1), bioconcentration of chloromethyl ethyl ether in the food chain is unlikely to occur(SRC).
Based upon the hydrolysis half-life of 18 sec for the structurally related chloromethyl methyl ether in pure water at 20 °C(1), significant volatilization from water is unlikely to occur(SRC). Based upon an estimated vapor pressure of 59 mm Hg(2), evaporation from surfaces and dry near-surface soil may be an important process(SRC).
DRINKING WATER: Chloromethyl ethyl ether has been listed in a literature review as a compound which has been found, but not quantified, in drinking water from unidentified sources(1), in the US(2) and in New Orleans(3); no dates were reported. Detection of considerable amounts of the compound in water is unlikely based upon the expected rapid hydrolysis in water based upon the hydrolysis half-life of 18 sec for the structurally related chloromethyl methyl ether in pure water at 20 °C(4).

Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Wash skin with soap and water. In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin. Keep victim calm and warm. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. (ERG, 2016)
