10. Fire Fighting Measures :

Charactersitcs of Hazard (the product causes burns of eyes, skin and mucous membranes – thermal decomposition can lead to release of irritating gases and vapors)

Hazardous Combustion Prodcuts (Carbon dioxide)

Fire-extinguishing methods and extinguishing media (use extinguishing measures that are appropriate to local circumstances and the surrounding environment – dry powder fire extinguishers)

11. Caution :

Do not disassemble or reassemble

Do not heat up above 60°C (140°F)

Do not dispose of in fire or directly short circuit
