Medical treatment. 【Inhalation】Rapidly leave the scene to the place with fresh air. Keep airway patency. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately and take medical treatment. 【Ingestion】Rinse mouth with water, drink milk or egg white and take medical treatment. |
Fire-fighting measures | 【Hazardous characteristics】Combustible with open fire and heat. React with strong oxidants. Decompose and release toxic gas when heated. 【Hazardous combustion products】Carbon monoxide, carbon dioxide, hydrogen chloride。 【Extinguishing method】Firefighters should wear gas mask, firefighter uniform and put out a fire upwind.Extinguishing agent: Water spray, foam, dry powder, carbon dioxide, sand. |
Leakage emergency treatment | 【Emergency treatment】Isolate leakage polluted area, restrict access, cut off the fire source. Suggest emergency treatment personnel wear dust mask (full cover) and protective clothing. Mix with sand, dry lime or soda ash. Collect in a dry, clean and covered container and move to safe place. For large spoll, collect and recycle or move to waste disposal site. |
Handling and storage | 【Operating precautions】Closed operation and provide adequate local exhaust ventilation. Operator must go through specialized training and strictly abide by the rules. Suggest operator wearing self-absorption filter respirator, chemical protective safety glasses, protective overall on infiltration and rubber gloves. Keep away from fire and heat source. No smoking in workplace. Used explosion-proof ventilation system and equipments. Avoid generating dust and the contact with oxidants and acids. Handle gently to avoid packaging and container damage. Equipped with appropriate type and qunatity of extinguishing equipments and leakage emergency treatment equipments. The empty container may have harmful residue. 【Storage precautions】Stored in cool and ventilated warehouse. Keep away from fire and heat source. Separate from oxidants and acids, etc. Equip with appropriate type and quantity extingguishing equipments. Storage area should be equipped with suitable material for leakage collection. |
Exposure control/personal protection | 【Monitoring methods】4-aminoantipyrine spectrophotometric method; solvent desorption - gas chromatography 【Engineering control】Strictly confined and provide adequate local exhause ventilation. Provide safe shower and eye washing equipment. 【Respiratory protection】When the air dust concentration exceeds standard, self-absorption filter respirators must be worn. Emergency rescue or evacuation, air respirator should be worn. 【Eye protection】Wear chemical safety glasses. 【Body protection】Wear protective overalls on infiltration. 【Hand protection】Wear rubber gloves. 【Other protection】No smoking, eating and drinking in working site. Clean thoroughly when the work is completed. Separately store the toxic polluted cloth and wash for use. Attention to personal hygiene. |
