TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Heating will cause rise in pressure with risk of bursting. See Notes. NO open flames. NO contact with hot surfaces. Powder, water spray, foam, carbon dioxide.
EXPLOSION See Notes.   In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE   PREVENT GENERATION OF MISTS!  
Inhalation Dizziness. Drowsiness. Headache. Nausea. Shortness of breath. Unconsciousness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! Dry skin. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes   Safety spectacles or face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING
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 let this chemical enter the environment. Personal protection: self-contained breathing apparatus. Xn Symbol
R: 20/21/22-40-66

UN Hazard Class: 9
UN Pack Group: III

Marine pollutant.


EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-90GM6-III
NFPA Code: H 3; F 1; R 0
Provision to contain effluent from fire extinguishing. Separated from strong oxidants, strong bases, many metals. Well closed. Ventilation along the floor.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
The vapour is heavier than air.

Chemical dangers
On contact with hot surfaces or flames this substance decomposes forming hydrogen chloride (see ICSC0163), phosgene (see ICSC0007), and other toxic gases. Reacts with strong oxidants, strong bases and metals such as sodium, potassium, magnesium and powdered aluminium. Attacks many plastic, rubber, steel and zinc.

Occupational exposure limits
TLV: 10 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: 10 ppm, 55 mg/m³ Peak limitation category: II(2); skin absorption (H); Carcinogen category: 3B; (DFG 2004).

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 rather quickly on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance may cause effects on the central nervous system, kidneys, liver, resulting in central nervous depression, liver impairment and kidney impairment. Exposure at high levels may result in unconsciousness.

Effects of long-term or repeated exposure
The liquid defats the skin.


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 114°C
Melting point: -36°C
Relative density (water = 1): 1.44
Solubility in water: none
Vapour pressure, kPa at 20°C: 2.5
Relative vapour density (air = 1): 4.6
Relative density of the vapour/air-mixture at 20°C (air = 1): 4.6
Explosive limits, vol% in air: 6-15.5
Octanol/water partition coefficient as log Pow: 2.35
The substance is harmful to aquatic organisms.

NOTES
Flash point unknown in literature.
Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions.
Use of alcoholic beverages enhances the harmful effect.
The relation between odour and the occupational exposure limit cannot be indicated.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification.
