Emergency measures
Skin contact: Remove contaminated clothing, use soap and water to thoroughly wash skin for at least 15 minutes.
Eye contact: Lift eyelid, use flowing water or saline to wash for at least 15 minutes. For medical treatment.
Inhalation: Rapidly move to the place with fresh air, keep the airway open. If breathing is difficult, give oxygen, Give artificial respiration immediately when breathing stopped and seek medical treatment.
Ingestion: Drink enough water, induce vomiting, seek medical treatment.
Fire prevention measures
Hazardous characteristics: Its vapor can form explosive mixture with air and will explode when meet fire and high-heat. React with oxidants.
Hazardous combustion product: Carbon monoxide
Fire fighting methods and extinguishing agents: Firefighters are required to wear gas masks, body wear firefighting suits, put out fire at upwind. Extinguishing media: foam, dry powder, carbon dioxide, sand.
Fire fighting precautions: Never use water
Accidental release measures
Emergency treatment: Isolate leakage polluted area and restrict access. Cut off the fire source. Emergency personnel should wear gas mask (full cover) and protective clothing. Used copper shovel to collect it in a dry, clean and covered container.
Handling and storage
Handling precautions: Closed production process operations, local exhaust ventilation. High concentration vapor contact should wear a filter respirator (half-mask), chemical safety glasses, protective overall on infiltration and anti-chemical gloves. Smoking, eating and drinking are forbidden in workplace. Take a shower and change clothing after work.
Storage pecautions: Store in a cool, ventilated warehouse. Away from fire and heat. Separately stored with oxidants, acids and food chemicals. No large amount or long time storage. Use explosion-proof lighting and ventilation facilities. Prohibit the use of easy to produce sparks mechanical equipments and tools. The storage area should be equipped with suitable leakage container in proper material.
