TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames. NO contact with oxidants.	Water spray, alcohol-resistant foam, dry powder, carbon dioxide.
EXPLOSION	Above 90°C explosive vapour/air mixtures may be formed.	Above 90°C use a closed system, ventilation.

EXPOSURE
Inhalation	Cough. Sore throat. Nausea. Convulsions. Dizziness. Laboured breathing. Pupillary constriction, muscle cramp, excessive salivation. Sweating. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	MAY BE ABSORBED! Skin burns. Pain. Redness. (See Inhalation).	Protective clothing. Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes	Pain. Redness. Severe deep burns.	Face shield.	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. Abdominal cramps. Diarrhoea. Vomiting. (See Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Ventilation. Remove all ignition sources. 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. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment.	UN Hazard Class: 6.1 UN Pack Group: III	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	SAFE STORAGE
NFPA Code: H3; F2; R0; Transport Emergency Card: TEC (R)-61GT1-III	Separated from strong acids, oxidants, metals, food and feedstuffs. Well closed. Ventilation along the floor.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Chemical dangers
Reacts with oxidants. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). The substance decomposes on burning producing nitrogen oxides.

Occupational exposure limits
TLV: 0.5 ppm as TWA; (skin); BEI issued; (ACGIH 2004).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation and 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 20°C.

Effects of short-term exposure
The substance is corrosive to the eyes and the skin. The vapour is irritating to the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system, resulting in convulsions and respiratory failure. Cholinesterase inhibition. Exposure may result in death. Medical observation is indicated. The effects may be delayed.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 222-232°C Melting point: -70°C Relative density (water = 1): 0.9 Solubility in water: at 20°C poor Vapour pressure, kPa at °C: 3.4 Relative vapour density (air = 1): 6 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 90°C c.c. Auto-ignition temperature: 165°C Explosive limits, vol% in air: 0.5-0.9	The substance is harmful to aquatic organisms.

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Card has been partly updated in April 2005. See section Occupational Exposure Limits.
