Most important symptoms/effects, acute and delayed
Ethyleneimine is classified as extremely toxic with a probable oral lethal dose of 5-50 mg/kg which is approximately 7 drops to 1 teaspoonful for a 70 kg (150 lb.) person. Ethyleneimine gives inadequate warning when over-exposure is by inhalation or skin absorption. It is a severe blistering agent, causing third degree chemical burns of the skin. Also, it has a corrosive effect on mucous membranes and may cause scarring of the esophagus. It is corrosive to eye tissue and may cause permanent corneal opacity and conjunctival scarring. Severe exposure may result in overwhelming pulmonary edema. Renal damage has been described. Hemorrhagic congestion of all internal organs has been observed. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 mg/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Cover skin bums with dry sterile dressings after decontamination . /Organic bases/Amines and related compounds/
SECTION 5: Firefighting measures
Suitable extinguishing media
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.
Specific hazards arising from the chemical
Irritating vapors are generated when heated. Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. May polymerize in fires with evolution of heat and container rupture. Runoff to sewer may create fire or explosion hazard. Ethyleneimine vapors are not inhibited and may form polymers in vents or flame arresters, resulting in stopping of the vents. Toxic oxides of nitrogen are produced during combustion. Upon treatment with sodium hypochlorite, it gives off the explosive compound 1-chloroazidine. Avoid acids, sodium hypochlorite. If heated under pressure, instability may result. Hazardous polymerization may occur. Avoid contact with silver or aluminum. Explosive polymerization may occur upon contact with acids. Polymerization is catalyzed by carbon dioxide. (EPA, 1998)
Special protective actions for fire-fighters
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.

SECTION 10: Stability and reactivity
Reactivity
100 ppm; NIOSH considers ethyleneimine to be a potential occupational carcinogen.
The substance may polymerize under the influence of acids and oxidizing materials. This generates fire or explosion hazard. On combustion, forms toxic and corrosive fumes including nitrogen oxides. The substance is a medium strong base.
Chemical stability
no data available
Possibility of hazardous reactions
The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed.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].

Carcinogenicity
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.
Reproductive toxicity
No information is available on the reproductive or developmental effects of ethyleneimine in humans or animals.
STOT-single exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. The substance may cause effects on the central nervous system, kidneys and liver. Exposure far above the OEL could cause death. The effects may be delayed.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. May cause heritable genetic damage to human germ cells.
Aspiration hazard
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

- Toxicity to daphnia and other aquatic invertebrates: EC0 - Daphnia magna - 26 mg/L - 24 h.
- Toxicity to algae: EC50 - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 8.85 mg/L - 72 h.
- Toxicity to microorganisms: EC10 - activated sludge, domestic - < 100 mg/L - 30 min. Remarks:Respiration rate.
Persistence and degradability
no data available
Bioaccumulative potential
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).
Mobility in soil
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).
Other adverse effects
no data available
SECTION 13: Disposal considerations
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.
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.

Other Information
Depending on the degree of exposure, periodic medical examination is indicated.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.Rest and medical observation are therefore essential.The odour warning when the exposure limit value is exceeded is insufficient.Ethyleneimine vapours are uninhibited and may form polymers in vents or flame arrestors causing stoppage of vents.Do NOT take working clothes home.
