The third part: risk overview.

Hazard category:

Invasion route:

Health hazard: Irritating to eyes and skin. Basically non-toxic.

Environmental hazard: it is harmful to the environment and can pollute the atmosphere.

Danger of explosion: This product is nonflammable and irritating.

Part IV: First aid measures

Skin contact: take off contaminated clothes and rinse with plenty of running water.

Eye contact: Lift eyelids and rinse with running water or normal saline. See a doctor.

Inhalation: Leave the site and go to a place with fresh air. If you have difficulty breathing, give oxygen. See a doctor.

Intake: Drink enough warm water to induce vomiting. See a doctor.

Part V: Fire Prevention Measures

Hazard characteristics: no special combustion and explosion characteristics. Pyrolysis will produce toxic sulfide smoke.

Harmful combustion products: sulfide.

Fire extinguishing method: Firefighters must wear full-body fire-proof and gas-proof clothing to extinguish the fire in the upwind direction. When putting out the fire, move the container from the fire to an open place as much as possible.

Part VI: Emergency treatment of leakage.

Emergency treatment: isolate the leaked contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and protective clothing. Avoid dust, carefully sweep it up, put it in a bag and move it to a safe place. If there is a large amount of leakage, cover it with plastic sheets and canvas. Collect and recycle or transport to the waste disposal site for treatment.

Part VII: Operation, Disposal and Storage

Precautions for operation: close the operation and strengthen ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that the operator wear a self-priming filter dust mask, chemical safety glasses, gas-proof overalls and rubber gloves. Avoid dust. Avoid contact with acids. Handle with care when handling to prevent the package from being damaged. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances behind.

Precautions for storage: Store in a cool and ventilated warehouse. Stay away from fire and heat sources. Should be stored separately from acids, etc. , and should not be mixed. The storage area should be equipped with suitable materials to control leakage.

Part VIII: Contact Control/Personal Protection
