ACUTE HAZARDS/
SYMPTOMS

FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with acids.
Water in large amounts, alcohol-resistant foam, powder. NO carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive. Risk of fire and explosion on contact with acids, oxidising substances.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Cough. Dizziness. Headache. Laboured breathing. Nausea. Vomiting. Symptoms may be delayed (see Notes).
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! Redness. Skin burns. Blisters.
    Protective clothing.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness. Pain. Severe deep burns.
    Face shield or eye protection in combination with breathing protection.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Vomiting (further see Inhalation).
    Do not eat, drink, or smoke during work. Wash hands before eating.
    Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Consult an expert! Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Fireproof. Separated from acids, oxidizing materials, food and feedstuffs. Dry. Store only if stabilized.
    Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS LIQUID , WITH PUNGENT ODOUR.

    PHYSICAL DANGERS:
    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.

    CHEMICAL DANGERS:
    The substance may polymerize under the influence of aqueous acidic conditions, acids, oxidising materials with fire or explosion hazard. On combustion, forms toxic and irritating fumes including nitrogen oxides. The substance is a medium strong base.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 0.5 ppm; 0.88 mg/m3 (skin) (ACGIH 1993-1994).


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its vapour and through the skin.

    INHALATION RISK:
    A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of vapour may cause lung oedema (see Notes). The substance may cause effects on the central nervous system, kidneys and liver. Exposure far above OEL may result in death. The effects may be delayed.

    EFFECTS OF LONG-TERM OR 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.

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water organisms.
    N O T E S
    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.
