Is flux harmful to people's health?
The flux inhalation toxicity to human body harm is extremely low, mainly is the brain central nervous inhibition, can cause dizziness and nausea, flux of high concentration can lead to loss of consciousness of human skin direct contact with liquid may cause mild skin irritation. Rinse with water. Flux to human eyes: 1.300ppm vapors irritate the eyes, and liquids can cause irritation to the eyes. If eating flux will cause sore throat, nausea and diarrhea. May be inhaled into the lungs and cause serious lung irritation when vomiting, destruction of lung tissue and chronic death: dissolve skin oils, long-term exposure may cause irritation.

The hazards of flux isopropyl alcohol are as follows: exposure to high concentrations of steam results in headache, drowsiness, ataxia, and irritation of the eyes, nose, and throat. Oral administration can cause nausea, vomiting, abdominal pain, diarrhea, drowsiness, coma and even death. Long term skin contact can cause dry and chapped skin. Workshop sanitation standard is 400ppm or so, general carbon dioxide is about 350ppm or so, so if chemical use area has partial exhaust air system, or workshop ventilated well, won't harm to human body commonlyA solder paste, heating will have two tin oxide fume produced, while soluble in Rosin paste process will also be released, tin is need to install local ventilation. If we plant every year to do testing, detection of concentration of lead fume and two side tin tin oxide, generally do not exceed the provisions of the state standard.There are a lot of flux, the ingredients are also different, generally there are rosin and alcohol substances, it is appropriate to avoid inhalation and ingestionWhat if protective measures are not, that ring factory work is poor, should at least do work in a well ventilated environment. Other work should also provide protective equipment, such as chemical protective gloves and activated carbon masks.As an operator, we should also learn to protect ourselves and develop good personal hygiene habits. We must not eat or drink water or wash hands before meals
