Is Soldering poisonous? Is it highly harmful to the human body?

In fact, we still need to pay attention to this at work. Generally, soldering is divided into lead-free and leaded types. If you don't exceed your workload frequently, the problem won't be too serious.

What are the hazards of soldering to the human body?

The main effects on the human nervous system are neurasthenia, polyneuropathy, and encephalopathy. Mild cases may present with general digestive tract symptoms, while severe cases may experience abdominal colic. Lead damage to the kidneys is more common in acute, subacute lead poisoning or severe chronic cases, presenting with aminoaciduria, decreased red blood cells, white blood cells, casts, and reduced renal function, suggesting toxic nephropathy, accompanied by hypertension. Female workers are more sensitive to lead, especially during pregnancy and lactation; it can cause infertility, abortion, premature birth, stillbirth, and infant lead poisoning. Male workers may experience decreased sperm count, weakened motility, and morphological changes. In addition, it can also cause hypothyroidism.

Is lead-free solder toxic?

Common tin-lead alloys, which have good electrical conductivity and low melting points, are used in the soldering process.

No solder is completely lead-free. Nowadays, most enterprises use lead-free Solder Wire. Generally speaking, lead-free processes do not cause lead fume to exceed the standard. However, soldering still has other hazards, such as Flux (rosin-like substances), which carries certain risks. It depends on the specific situation. If the solder used is lead-containing, it will be somewhat harmful to the body.

So how to prevent it? As follows:

1. Take a break for a while. General repair work: take a break every 1 hour, about 15 minutes, to relieve fatigue, because resistance is weakest when one is tired.

2. Smoke less and drink plenty of water; in this way, most absorbed harmful substances can be excreted during the day.

3. Drink mung bean soup or honey water before going to bed. This reduces internal heat, helps your mood, and mung beans and honey can eliminate a large amount of absorbed lead and radiation.

4. Radiation should be avoided as much as possible. Use a personal phone (PHS) more and mobile phones less; use your mobile phone only when you cannot go out. It is suggested that everyone

5. You can use a PPD soldering tip to make the soldering iron hotter, so that once the temperature is reached, less soldering oil and rosin can be used, reducing harm to the body.

6. When the soldering oil starts to smoke, try to tilt your head slightly to the side. When washing flux away with water, also tilt your head slightly to the side, and try to hold your breath.

7. Use less thinner and more alcohol. Brushing with alcohol for a longer time has about the same effect.

8. Wash your hands thoroughly.

9. Before going to bed, take a bath. Try to go to bed early and get up early to ensure adequate sleep. As long as you sleep well, impurities can basically be excreted from the body.

10. Novices just entering the industry who are practicing soldering skills can practice with a mask on. Newcomers tend to practice for a relatively long time every day, which is the period when harm to the body is greatest, so masks are a must!
