Is solder toxic?

Is soldering poisonous? That's the positive answer. Solder tints contain not only tin, but also fluxes such as rosin. The main chemical components of rosin are rosin acid and pepper acid. The gas produced after the oxidation of this type of material (also containing tar) has a strong thorny taste. After being inhaled by the human body, tar accumulates in the lungs and causes lung tissue lesions, which is similar to smoking. However, a small amount of such gases will not cause human discomfort.
 
Solder toxic precautions
 
1. The use of engineering and technical measures to control the spread of harmful lead should adopt engineering and technical measures to eliminate and mitigate hazards as soon as possible, and prevent and control occupational lead poisoning hazards, with particular emphasis on the following aspects.
 
(1) Adopt appropriate production processes, including feeding and discharging packaging, etc., to reduce air pollution, pay attention to temperature and humidity during storage, and replace highly toxic substances with low-toxic substances;
 
(2) The operation of dust, toxic vapor or gas is carried out under confined conditions, supplemented by local suction and when hot toxic gas occurs, local exhaust hoods may be used to control the proliferation of occupational lead harmful factors;
 
(3) Take long-distance operation and automatic operation, supplemented with personal protective equipment to prevent direct contact.
 
2. Controlling human factors In order to prevent occupational lead harmful factors from harming contacts, it is important to strengthen first- and second-level prevention in order to detect the affected people early. Strengthen personal protection. Personal protective equipment includes respiratory protective gear (dust mask, face mask), face shield (UV protection), protective clothing (acid, alkali, high temperature), gloves (vibration proof), shoes, etc. And choose.
3. Strengthen health education Make people correctly understand the occupational lead harmful factors, improve self-care awareness, consciously participate in prevention, and do a good job of personal hygiene and develop good health habits, do not smoke, dine in the workshop.
