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.  Use carbon dioxide, powder, water spray. 
EXPLOSION Above 87°C explosive vapour/air mixtures may be formed.  Above 87°C use a closed system and ventilation.   
 
EXPOSURE See Notes.     
Inhalation   Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for inorganic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Remove vapour with fine water spray.   
EC Classification
 
UN Classification
UN Hazard Class: 9; UN Pack Group: III 
GHS Classification
Signal: Warning
Combustible liquid
Causes mild skin irritation
Toxic to aquatic life 

EMERGENCY RESPONSE SAFE STORAGE
  Provision to contain effluent from fire extinguishing. Separated from strong bases and strong oxidants. Cool. Keep in a well-ventilated room. Store in an area without drain or sewer access. 

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

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Decomposes on heating. This produces carbon monoxide and vinyl chloride. Reacts violently with strong oxidants and strong bases. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

Routes of exposure
 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is mildly irritating to the skin. 

Effects of long-term or repeated exposure
