出出国Explosion hazard: This product is nonflammable and corrosive. It can cau burns and nsitization.
The fourth part: first aid measures
Skin contact: remove contaminated clothing and rin with plenty of running water.
Eye contact: lift eyelids and rin with flowing water or saline. Medical treatment.
Inhalation: quickly escape from the scene to the fresh air. Keep airway clear. If breathing is difficult, give oxygen. If breathing stops, take artificial respiration immediately. Medical treatment.
Ingestion: drink plenty of warm water to induce vomiting. Medical treatment.lleck
The fifth part: fire protection measures
Hazardous property: a poisonous corrosive gas produced by the decomposition of high heat. Corrosive.
Harmful combustion products: chloride.
Fire extinguishing method: u fog water, carbon dioxide and sand to extinguish fire.
The sixth part: emergency treatment of leakage
Emergency treatment: quickly evacuate the personnel from the contaminated area to the safe area, and isolate and strictly restrict access. It is recommended that emergency personnel wear lf-contai
ned positive pressure breathing apparatus and wear acid proof working clothes. Do not touch the leak directly. Cut off the leak as much as possible. Small amount of leakage: absorbed by sand, vermiculite, or other inert material. A large leak: construct a barrierpit to contain. Foam mulch to reduce steam damage. Transfer to tank car or special collector by pump, recycle or transport to waste disposal site.
The venth part: operation, disposal and storage
Operation notes: airtight operation, comprehensive ventilation. Operators must undergo special training and strictly follow the operating procedures. It is recommended that operators wear direct gas masks (mi masks), wear chemical safety goggles, wear antiptic clothing, and wear rubber gloves. Prevent steam from leaking into the air in the workplace. Avoid contact with acids. Remove light and light
when handling and prevent packing and container damage. Equipped with emergency disposal equipment for leakage. Empty containers may leave harmful substances.
Storage: store in a cool and airy warehou. Keep away from fire and heat. The temperature should not exceed 30 DEG C. Should be stored parately with acids, must not be mixed storage. The stora
ge area shall be equipped with emergency disposal equipment and suitable storage materials. The eighth part: contact control / individual protection
