Toxic. Soldering fumes generated by the potential to cause tin pneumoconiosis, usually occupational hazards is a greater impact on the respiratory tract, lungs; if the tin oxide, tin dioxide inhalation, according to the International Chemical Safety Card: may be mechanical irritation of the respiratory tract, long-term repeated exposure, may be on the lungs damage, resulting in benign pneumoconiosis (tin pneumoconiosis).

Expanded Information
Lead-free solder
It refers to the solder that complies with the EU ROHS standard, which explicitly requires that the lead content must be less than 1000PPM, so lead-free solder does not mean that it does not contain lead at all. However, compared to leaded solder, the use of lead-free solder is much less harmful to the human body.
The use of lead-free solder wire note:
1, keep the working environment ventilation.
2, less smoking and drink more water, which can discharge most of the harmful substances absorbed.
3, wash your hands diligently, after completing the welding work, wash your hands before meals and drinking water.
4, wear a mask when working.
