Is soldering iron solder toxic?
A netizen touted that he used soldering iron soldering in the PCB factory for a whole year, are feeling the body began to feel uncomfortable, the abdomen is a little swollen, solder is toxic? Is not lead poisoning.
In fact, this also depends on the work with a soldering iron soldering leaded solder wire or lead-free, and the need for regular checks of blood lead, not exceeding the standard will not have a problem at all, solder is toxic?
Normally speaking, if in accordance with national standards for protection and procurement of raw materials, solder will not cause significant harm. Nowadays, we basically use lead-free products.
Lead is a toxic substance, the human body absorbs too much will cause lead poisoning, intake of low doses may have an impact on human intelligence, nervous system and reproductive system.
The alloy of tin and lead, which is commonly used as solder, has good electrical conductivity of the metal and a low melting point, so it has long been used in the soldering process. Its toxicity comes mainly from lead. Lead fumes from soldering can easily lead to lead poisoning.
Lead metal may produce lead compounds, all of which are classified as hazardous substances, and in humans lead affects the central nervous system and the kidneys.
The environmental toxicity of lead to a number of organisms is well established. Blood lead concentrations of 10 μg/dl or more can produce sensitive biochemical effects, and clinical lead poisoning can result from prolonged exposure that results in blood lead concentrations of more than 60 to 70 μg/dl.
Lead is definitely toxic, not to mention the impact of solder on the body is not big, is the general metal, more will be poisoned, soldering, there will be smoke, which contains a harmful element to the body.
When working, it is best to wear a mask, but more or less will still have a little impact, of course, if you can use lead-free solder wire, will be much safer than leaded.
How to prevent soldering iron wire toxicity?
First of all PCB factories in the soldering iron soldering components to use ROHS tin wire, and to do a good job of prevention:
For example, with gloves, masks or gas masks, the workplace attention to ventilation, exhaust system is good, pay attention to cleaning after work, drink milk is also a way to prevent lead toxicity in solder.
1, to rest for a period of time, generally 1 hour to rest for about 15 minutes to relieve fatigue, because fatigue resistance is the worst.
2, less smoking drink more water so that during the day can eliminate most of the harmful substances absorbed.
3, drink green bean soup or honey water before going to bed so that you can lower the fire on the mood to help and green beans and honey can exclude the absorption of a large number of lead and radiation.
4, you can make the soldering iron a little brighter, try to use PPD soldering head, so that the temperature reached can be less soldering oil and rosin, to reduce the harm to the body.
5, soldering oil solder smoke when you try to head to the side of the point when brushing the water to the side of the point when the head to the side of the point as much as possible to hold your breath.
6, more alcohol, brush with alcohol for a while more effect is almost the same.
7, after welding to wash your hands.
8, before going to bed to take a bath as early as possible, to ensure adequate sleep, as long as you sleep well, impurities can basically be discharged with the body.
9, work with a mask.
