SECTION 2: Hazards identification

Emergency overview: Combustible GHS risk category: No data available

Hazard pictograms

Warning words: Warning Dangerous information: Its powder can form explosive mixture when mixed with air. In case of high heat of open fire, it may cause combustion and explosion. Combustion and exposure to high heat produce toxic and corrosive fumes.

Precautionary statements

Avoid inhaling dust, smoke, gas, smoke, steam and spray The containers and pipelines containing this product shall be replaced by inert gas before overhaul and hot work, and only after qualified analysis. Preventive measures: Away from fire, heat. Should be stored in isolation from strong oxidizing agents. Accident response: Isolate the leakage pollution area and restrict access. Eliminate all sources of ignition. Emergency personnel are advised to wear dust masks and general work clothes. Cut off the leakage source as much as possible. Cover spills with plastic sheets to reduce flying. Keep water out of the container. Collect the spill with a clean shovel and place it in a clean, dry container with a loose lid. Remove the container from the spill area. Safe storage: Store in cool and ventilated warehouse. Package sealed. Waste disposal: Rinse with water.
