General First Aid:
· Call 911 or emergency medical service.
· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.
· Move victim to fresh air if it can be done safely.
· Administer oxygen if breathing is difficult.
· If victim is not breathing:
-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.
-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).
-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.
· Remove and isolate contaminated clothing and shoes.
· For minor skin contact, avoid spreading material on unaffected skin.
· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.
· For severe burns, immediate medical attention is required.
· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.
Do not extinguish fire unless flow can be stopped; use water in flooding quantities as a fog. Solid streams of water may be ineffective. Apply water from as far a distance as possible.
If tank car or truck is involved in fire, isolate the surrounding area in a 1/2 mile radius.
Dry chemical, alcohol foam, or carbon dioxide are useful for small fires. For large fires: water spray, fog or foam. (EPA, 1998)
Use water in large amounts, alcohol-resistant foam, powder. NO carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
Use dry chemical, "alcohol resistant" foam, carbon dioxide, or water spray. Water may be ineffective. Use water spray to keep fire-exposed containers cool. Approach fire from upwind to avoid hazardous vapors & toxic decomp products. Explosive decomp may occur under fire conditions. Fight fire from protected location or maximum possible distance.
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide. /Ethyleneimine, stabilized/
Use dry-chemical, foam, and carbon dioxide extinguishers. Water spray, though ineffective to extinguish, may help to keep fire-exposed containers cool. Fight fires from safe distances.
Evacuation: If fire becomes uncontrollable or container is exposed to direct flame - consider evacuation of one (1) mile radius. /Ethyleneimine, stabilized/
Flammable liquid. Vapors are heavier than air & may travel to a source of ignition & flashback. Closed containers may rupture violently when heated. Combustion by-products include oxides of nitrogen.

ETHYLENEIMINE vapors are not inhibited and may form polymers in vents or flame arresters, resulting in stopping of the vents. Produces toxic oxides of nitrogen during combustion. Reacts with sodium hypochlorite and other chlorinating agents to give the explosive compound 1-chloroazidine. Decomposes if heated under pressure. or else hazardous polymerization may occur. Incompatible with silver or aluminum, which induce polymerization May polymerize explosively upon contact with acids. Polymerization is catalyzed by carbon dioxide [EPA, 1998].
/Aziridine/ gives the explosive 1-chloroazidine on treatment with /chlorinating agents/ eg sodium hypochlorite solution.
Explosive silver derivatives may be formed in contact with silver or its alloys, including silver solder, which is therefore unsuitable in handling equipment.
Polymerizes explosively in presence of acids [Note: Explosive silver derivatives may be formed with silver alloys (e.g., silver solder)].
Mixing acetic acid and ethyleneimine in a closed container caused the temperature and pressure to increase. (It was observed when equimolar quantities of 2 chemicals were mixed in a closed container. In some cases the changes were solely vapor pressure effects due to heat of solution.)

Evaluation: No epidemiological data relevant to the carcinogenicity of aziridine were available. There is limited evidence in experimental animals for the carcinogenicity of aziridine. Overall Evaluation: Aziridine is possibly carcinogenic to humans (Group 2B). In making the overall evaluation, the Working Group took into consideration that aziridine is a direct acting alkylating agent which is mutagenic in a wide range of test systems and forms DNA adducts that are promutagenic.
A3: Confirmed animal carcinogen with unknown relevance to humans.

Frequency of somatic point mutation induced by ethylenimine in Drosophila melanogaster larvae (heterozygous females and hemizygous males) was reduced after caffeine treatments, but it increased the frequency of chromosome aberrations and mitotic recombinations that were induced.
Barley (Hordeum vulgare) seeds were treated with ethylenimine and diethyl sulfate separate and in combination. Combination of the two was simultaneous (EI + diethyl sulfate) or sequential (EI followed by diethyl sulfate or diethyl sulfate followed by EI). Frequency of chromosome aberrations and chlorophyll mutation induced by EI was significantly higher than that induced by diethyl sulfate. Highest frequency of mutation was obtained with EI followed by diethyl sulfate, next (in descending order) was EI + diethyl sulfate, EI alone, diethyl sulfate followed by EI, and diethyl sulfate alone. Interaction of these agents with genetic material is complex and specific, depending on sequence in which the mutagens are applied.
Sodium selenite significantly decreased frequency of chromosome aberrations induced in wheat by ethyleneimine. Optimum concentration of sodium selenite ranged from 0.01 to 0.1 ug/mL. At these concentrations it displayed high antimutagenic activity without affecting cell division.
When barley seeds were treated wiith ethylenimine and cysteine, mutations induced by ethylenimine were markedly suppressed by cysteine.

The substance is harmful to aquatic organisms.
Ethyleneimine's production and use as an intermediate and monomer for fuel-oil and lubricant refining, ion exchange, protective coatings, pharmaceuticals, adhesives, polymer stabilizers, and surfactants may result in its release to the environment through various waste streams. If released to air, a vapor pressure of 213 mm Hg at 25 °C indicates ethyleneimine will exist solely as a vapor in the atmosphere. Vapor-phase ethyleneimine will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.6 days. Ethyleneimine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, ethyleneimine is expected to have very high mobility based upon an estimated Koc of 2. However, the pKa of ethyleneimine is 8.04, indicating that this compound will partially exist as a cation in the environment and cations generally do adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil surfaces is expected to occur based upon an estimated Henry's Law constant of 1.2X10-5 atm-cu m/mole. Ethyleneimine may volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data were not available. If released into water, ethyleneimine is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. However volatilization will be attenuated due to its cationic state under environmental conditions. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Attenuation is pH dependent with little volatilization expected under acidic conditions. Estimated volatilization half-lives for a model river and model lake are 2 and 17 days, respectively. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. A hydrolysis half-life of 154 days suggests that hydrolysis is not expected to be an important environmental fate process. Occupational exposure to ethyleneimine may occur through inhalation and dermal contact with this compound at workplaces where ethyleneimine is produced or used. (SRC)
Ethyleneimine is not known to occur in nature(1).
Ethyleneimine's production and use as an intermediate and monomer for fuel-oil and lubricant refining, ion exchange, protective coatings, pharmaceuticals, adhesives, polymer stabilizers, and surfactants(1) may result in its release to the environment through various waste streams(SRC).
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2(SRC), determined from an assigned water solubility of 1X10+6 mg/L (miscible)(2) and a regression-derived equation(3), indicates that ethyleneimine is expected to have very high mobility in soil(SRC). However, the pKa of ethyleneimine is 8.04(4), indicating that this compound will partially exist as a cation in the environment and cations generally do adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of ethyleneimine from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.2X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 213 mm Hg(6), and assigned value for water solubility(2). Ethyleneimine is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(6). Biodegradation data were not available(SRC, 2006).
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2(SRC), determined from an assigned water solubility of 1X10+6 mg/L (miscible)(2) and a regression-derived equation(3), indicates that ethyleneimine is not expected to adsorb to suspended solids and sediment(SRC). However volatilization will be attenuated as ethyleneimine exits as a cation (pKa = 8.04(4)) under environmental conditions and will therefore absorb to solids and sediment. Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 1.2X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 213 mm Hg(5), and water solubility(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2 and 17 days, respectively(SRC). Attenuation is pH dependent with little volatilization expected under acidic conditions(6). According to a classification scheme(6), an estimated BCF of 3(SRC), from an estimated log Kow(8) and a regression-derived equation(9), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation data were not available(SRC, 2006).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), ethyleneimine, which has a vapor pressure of 213 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase ethyleneimine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 2.6 days(SRC), calculated from its rate constant of 6.10X10-12 cu cm/molecule-sec at 25 °C(3). Ethyleneimine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
The rate constant for the vapor-phase reaction of ethyleneimine with photochemically-produced hydroxyl radicals is 6.10X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 2.6 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Ethyleneimine undergoes hydrolysis at neutral pH with a half-life of 154 days(2) yielding ethanolamine(3). It also complexes with metal salts(3). Ethyleneimine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
An estimated BCF of 3 was calculated for ethyleneimine(SRC), using an estimated log Kow of -0.28(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of ethyleneimine is estimated as 2(SRC), using an assigned value for water solubility of 1X10+6 mg/L (miscible)(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that ethyleneimine is expected to have very high mobility in soil. However, the pKa of ethyleneimine is 8.04(4), indicating that this compound will partially exist as a cation the environment and cations generally do adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Ethyleneimine readily complexes with metal salts(6) which may be present in soil(SRC).
The Henry's Law constant for ethyleneimine is estimated as 1.2X10-5 atm-cu m/mole(SRC) derived from its vapor pressure, 213 mm Hg(1), and assigned value for water solubility of 1X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that ethyleneimine is expected to volatilize from water surfaces(3). However volatilization will be attenuated as ethyleneimine exits as a cation (pKa = 8.04(4)) under environmental conditions and will therefore absorb to suspended solids and sediment. Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 2 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 17 days(SRC). Ethyleneimine's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of ethyleneimine from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).
