5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media


5.2 Specific hazards arising from the chemical

May form phosgene or hydrogen chloride in fires. There is danger of explosion when ethers are heated or exposed to flames or sparks. Ethers tend to form peroxides; when ethers containing peroxides are heated, they can detonate. May be ignited by heat, sparks, or flames. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Decomposes in the presence of moisture to form hydrochloric acid. Emits toxic fumes when heated to decomposition. Reacts vigorously with oleum and chlorosulfonic acid. Ethers tend to form peroxides upon standing. Heating peroxide-containing ethers can cause detonation. (EPA, 1998)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna (cladoceran) 238,000 ug/l/48 hr /in static and unmeasured methodologies
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

Bis(2-chloroethyl) ether was added to Ohio River water at pH 7.2 and 22-25°C(1). Thirty-five days following the addition of bis(2-chloroethyl) ether to the water, 50% of the carbon dioxide theoretically derivable from bis(2-chloroethyl) ether was recovered. After a second addition of bis(2-chloroethyl) ether, only 9-10 days were required to observe 50% recovery of theoretical carbon dioxide, suggesting acclimation was necessary for optimal biodegradation rates(1). The absence of evidence of biodegradation in another study(2) may be attributed to an insufficiently long acclimation period (18 days)(SRC). Bis(2-chloroethyl) ether, present at 100 mg/l, reached 8.3% of its theoretical BOD in 3 weeks using an activated sludge inoculum(3).

12.3 Bioaccumulative potential

A BCF of 0.4 to 1.3 in carp(1) and a BCF of 11 in bluegills exposed to bis(2-chloroethyl) ether for 14 days(2) was observed. According to a classification scheme(3), these BCF values suggest that the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

The Koc of bis(2- chloroethyl) ether is estimated as approximately 120(SRC), using a log Kow of 1.29(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that bis(2-chloroethyl) ether is expected to have high mobility in soil(SRC). In a 140 cm long column containing Lincoln fine sand collected in Ada, OK, 86% of the applied bis(2-chloroethyl) ether reached 140 cm, indicating minimal adsorption to this soil(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
