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 alcohol-resistant foam, powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE      
Inhalation Dizziness. Lethargy.  Use ventilation. Use local exhaust.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Nausea.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
COLOURLESS OILY LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes and gases (phthalic anhydride - see ICSC 0315). Attacks some plastics. 

Occupational exposure limits
TLV: 5mg/m³ as TWA; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2005). 

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 will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
