After inhalation:Supply fresh air; consult doctor in case of complaints. After skin contact:Rinse cautiously with water for several minutes. After eye contact:Rinse opened eye for several minutes under running water. After swallowing:Rinse out mouth and then drink plenty of not induce vomiting; call for medical help for a doctor immediately.

Special hazards arising from the substance or mixtureVapours are heavier than air and may spread along explosive mixtures with air at elevated of hazardous combustion gases or vapours possible in the event of fire. Advice for firefighters Protective equipment:Wear positive-pressure self-contained breathing apparatus (SCBA) and protective fire fighting clothing(includes fire fighting helmet, coat, trousers, boots, and gloves).

Environmental precautions:Dilute with plenty of not allow to enter sewers/ surface or ground water. Methods and material for containment and cleaning up:Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).Dispose contaminated material as waste according to item 13. Reference to other sectionsSee Section 7 for information on safe Section 8 for information on personal protection Section 13 for disposal Handling and storage Precautions for safe handlingUse personal protective equipment as local exhaust ventilation if dust and aerosol are formed during handling.
