IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation of
its vapour, through the skin and by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. The vapour mixes well with air, A harmful contamination of the air can be reached very quickly
explosive mixtures are easily formed. on evaporation of this substance at 20掳C.
Chemical dangers Effects of short-term exposure
The substance may polymerize under the influence of acid(s), The substance is corrosive to the eyes, the skin and the
oxidising materials with fire or explosion hazard. On respiratory tract. Corrosive on ingestion. Inhalation of vapour
combustion, forms toxic and corrosive fumes including nitrogen may cause lung oedema (see Notes). The substance may
oxides. The substance is a medium strong base. cause effects on the central nervous system, kidneys and liver.
Exposure far above OEL may result in death. The effects may
be delayed.
Occupational exposure limits
TLV: 0.5 ppm (skin); A3; (ACGIH 2002).
Effects of long-term or repeated exposure
MAK: H; Carcinogen category: 2; Germ cell mutagen group: 3A;
(DFG 2002). 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.
PHYSICAL PROPERTIES
Boiling point: 56-57掳C Relative density of the vapour/air-mixture at 20掳C (air = 1): 1.1
Melting point: -74掳C Flash point: -11掳C c.c.
Relative density (water = 1): 0.8 Auto-ignition temperature: 322掳C
Solubility in water: miscible Explosive limits, vol% in air: 3.3-55
Vapour pressure, kPa at 20掳C: 21.3 Octanol/water partition coefficient as log Pow: -0.36
Relative vapour density (air = 1): 1.5
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
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.
