First aid measures
Announce
edit
Skin contact: Take off contaminated clothes immediately, and wash thoroughly with flowing clean water or 5% sodium thiosulfate solution for at least 20 minutes.Get medical attention.
Eye contact: immediately lift the eyelid, and thoroughly flush it with a large amount of flowing water or physiological saline for at least 15 minutes.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.When breathing and heartbeat stop, perform artificial respiration (not mouth to mouth) and external chest compression immediately.Inhale isoamyl nitrite and seek medical advice.
Ingestion: drink enough warm water to induce vomiting.Use 1:5000 potassium permanganate or 5% sodium thiosulfate solution for gastric lavage.Get medical attention.
Fire fighting measures

edit
Hazard characteristics: non combustible.It will produce highly toxic cyanide gas when exposed to high heat or acid.Reacts violently with nitrate, nitrite and chlorate, which may cause explosion.When exposed to acid or air, it can absorb water and carbon dioxide and decompose into highly toxic hydrogen cyanide gas.
Fire extinguishing method: the product is non combustible.In case of fire, try to rescue the goods to prevent package damage and environmental pollution.Firefighters must wear gas masks and full body fire-fighting clothes to extinguish the fire in the upwind direction.
Extinguishing agent: dry powder, sand.It is forbidden to use carbon dioxide and acid-base fire extinguishing agent to extinguish the fire.
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear dust masks (full face masks) and gas suits.Do not touch the leakage directly.
Small amount of leakage: collect it in a dry, clean and covered container with a clean shovel.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.
Handling and storage
Announce
edit
Precautions for operation: it shall be strictly sealed, and sufficient local exhaust and general ventilation shall be provided.The operation shall be mechanized and automated as far as possible.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that the operator wear a hood type electric air supply filter type dust respirator, a one-piece adhesive tape gas suit and rubber gloves.Avoid dust generation.Avoid contact with oxidants and acids.Load and unload gently during transportation to prevent damage to packaging and containers.Provide leakage emergency treatment equipment.Empty containers may leave harmful substances.
Precautions for storage: store in a cool and ventilated warehouse.Keep away from kindling and heat sources.Packing and sealing.It shall be stored separately from oxidants, acids and edible chemicals, and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.The "five pairs" management system for extremely toxic substances shall be strictly implemented.
