TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ 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 acid(s).	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 acid(s), oxidants.	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		AVOID ALL CONTACT!	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 may be needed. Refer for medical attention.
•SKIN	MAY BE ABSORBED! Redness. Skin burns. Blisters.	Protective gloves. 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	Abdominal pain. Burning sensation. Vomiting. Shock or collapse. (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.

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 acid(s), oxidising materials with fire or explosion hazard. On combustion, forms toxic and corrosive fumes including nitrogen oxides. The substance is a medium strong base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 ppm (skin); A3; (ACGIH 2002).
MAK: H;
Carcinogen category: 2; Germ cell mutagen group: 3A;
(DFG 2002).
OSHA PEL: 1910.1012 See Appendix B
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Potential occupational carcinogen 100 ppm

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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. 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. May cause heritable genetic damage to human germ cells.

ENVIRONMENTAL
DATA

The substance is harmful to aquatic 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. Do NOT take working clothes home.
