TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 34C explosive vapour/air mixtures may be formed.
Above 34C closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

Inhalation Burning sensation. Cough. Shortness of breath. Sore throat. Wheezing.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin Redness. Skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Blurred vision. 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. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention. Do NOT induce vomiting.
SPILLAGE DISPOSAL PACKAGING & LABELLING

ETHYLENEDIAMINE ICSC: 0269
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW HYGROSCOPIC LIQUID, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes (nitrogen oxides). The substance is a medium strong base. Reacts violently with chlorinated organic compounds, strong oxidants acids.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; (skin); A4; (ACGIH 2003).
MAK: 10 ppm, 25 mg/m; Peak limitation category: II(2); Pregnancy risk group: D; (DFG 2002).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather 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. Corrosive on ingestion.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma.
PHYSICAL PROPERTIES
Boiling point: 117C
Melting point: 8.5C
Relative density (water = 1): 0.9
Solubility in water: miscible
Vapour pressure, kPa at 20C: 1.4
Relative vapour density (air = 1): 2.1
Relative density of the vapour/air-mixture at 20C (air = 1): 1.01
Flash point: 34C (c.c.)
Auto-ignition temperature: 385C
Explosive limits, vol% in air: 2.5-16.6
Octanol/water partition coefficient as log Pow: -1.2
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
The symptoms of asthma 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. Anyone who has shown symptoms of asthma due to this substance should never again come into contact with this substance. Do NOT take working clothes home.
