TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use powder, AFFF, foam, carbon dioxide. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Burning sensation. Cough. Dizziness. Headache. Nausea. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Burning sensation. Numbness. Tingling sensation. Itching.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Convulsions. Vomiting. Further see Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

Chemical dangers
Decomposes above 220°C . This produces toxic fumes including hydrogen cyanide (see ICSC 0492) and hydrogen chloride (see ICSC 0163). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

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 irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. This may result in facial sensation such as tingling; itching or burning. 

Effects of long-term or repeated exposure
