What are the hazards of potassium fluoride?
Potassium fluoride is also known as the fluoride salt of potassium. The chemical formula is KF, the molecular weight is 58.10, and it is hygroscopic. Dissolved in water. However, it reacts with acids to release corrosive and irritating hydrofluoric suan, which can corrode glass and has certain harmfulness. What are the hazards of potassium fluoride? Let's follow the potassium fluoride manufacturers. a bit.

After inhalation, it can be caused by inflammation of the throat and bronchus, edema, spasm, chemical pneumonia, and pulmonary edema. Poisoning has a burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
福彩3D走势图Explosion hazard: This product is non-combustible, toxic, irritating, and seriously damages mucous membranes, upper respiratory tract, eyes and skin. Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water for at least 15 minutes. Seek medical attention.
Eye contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.
Inhalation: Remove quickly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Ingestion: Rinse mouth with water and drink milk or egg white. Seek medical attention. Hazardous combustion products: hydrogen fluoride.
Extinguishing method: Extinguish with plenty of water. Use misty water to disperse smoke and irritating gases. Emergency treatment: Isolation of contaminated areas and restrictions on access. It is recommended that emergency personnel wear a dust mask (full face mask) and wear a protective suit. Do not touch the spill directly.
Small spills: Avoid dust and collect in a dry, clean, covered container with a clean shovel. It can also be rinsed with a large amount of water, diluted in water and placed in the wastewater system.
Large amount of leakage: collected or transported to a waste disposal site for disposal.
福彩3D走势图Operational precautions: closed operation, local exhaust. Operators must be specially trained to strictly follow the operating procedures. Operators are advised to wear a hood-type electric air-filtered dust-proof respirator, a tape anti-drug, and latex gloves. Avoid dust. Avoid contact with acids. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.
In summary, the information on the hazard of potassium fluoride should be stored separately from the acid and food chemicals, and should not be mixed. The storage area should be provided with suitable materials to contain spills.
