The components of electroplating solution used for circuit board electroplating in production line are lead, tin, nickel and copper sulfate, which have certain volatility and can be absorbed by skin and mucosa to cause diseases. Any one of them is harmful to human body, so we should know the protection and prevention of occupational diseases in the production process. Harm of copper sulfate to health: it has a strong stimulating effect on gastrointestinal tract, causing nausea, vomiting, copper taste in mouth and burning sensation in stomach. In severe cases, abdominal cramps, hematemesis and black stool will occur. Can cause serious renal damage and hemolysis, jaundice, anemia, hepatomegaly, hemoglobinuria, acute renal failure. Irritating to eyes and skin. Dermatitis, nose and eye irritation and gastrointestinal symptoms may occur after long-term contact. 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. Ingestion: gastric lavage with 0. 1% potassium ferrocyanide or sodium thiosulfate by mistake. Give milk or egg whites. Precautions for medical operation: close the operation and provide sufficient local 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 and bases. When handling, handle with care to prevent the packaging and containers from being damaged. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances behind. Storage precautions should be stored in a cool, dry and well-ventilated warehouse. Stay away from fire and heat sources. Keep the container sealed. Should be stored separately from acid, alkali and edible chemicals, and should not be mixed. The storage area should be equipped with suitable materials to control leakage. In addition, the pH value of sewage discharged from electroplating factory is less than 7, and it contains copper sulfate. In order to remove toxic copper sulfate and adjust it to neutrality, calcium oxide can be used.
