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 47°C explosive vapour/air mixtures may be formed.
Above 47°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. 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 Pain. Redness. Blisters. Skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Pain. Redness. Severe deep burns. Loss of vision.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Burning sensation. Abdominal pain. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Cautiously neutralize remainder. Do NOT let this chemical enter the environment. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).

EMERGENCY RESPONSE STORAGE
Transport Emergency Card: TEC (R)-80G15 NFPA Code: H3; F2; R0;
Fireproof. Separated from strong oxidants, acids, food and feedstuffs.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides. The substance is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants. Attacks many metals.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached 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. Inhalation of vapour may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.


PHYSICAL PROPERTIES
Boiling point: 159°C
Melting point: -59°C
Relative density (water = 1): 0.76
Solubility in water, g/100 ml: 0.35, poor
Vapour pressure, kPa at 20°C: 0.27
Relative vapour density (air = 1): 4.5
Flash point: 47°C
Auto-ignition temperature: 260°C
Explosive limits, vol% in air: 1.1-?
Octanol/water partition coefficient as log Pow: 2.83

ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.

NOTES
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 is therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
