The harm of solder smoke to human body?

The smoke and dust produced by welding may cause tin pneumoconiosis, and the usual occupational hazard is that it has a great impact on respiratory tract and lungs; If tin oxide and tin dioxide are inhaled, according to the international chemical safety card, it may cause mechanical irritation to the respiratory tract, and long-term repeated contact may cause lung injury, leading to benign pneumoconiosis (tin pneumoconiosis). However, it is not directly mentioned in the Catalogue of Occupational Hazards. The contents of tin are as follows:

(1) lead and its compounds (lead dust, lead smoke and lead compounds, excluding tetraethyl lead)

Possible occupational diseases: poisoning by lead and its compounds

Industry example:

(1) heavy nonferrous metal smelting industry: tin ore burden before furnace, tin ore fuming; Tin smelting, tin refining, tin ore fuming, tin electrolysis

(2) Electrical machinery and equipment manufacturing: wire and cable tin plating.

(3) Electronic and communication equipment manufacturing: circuit substrate sintering, component tin plating, component wave soldering and component manual welding.

Extended information Under the problem that manual welding is harmful to health, it is suggested that there are several ways to solve the health problem:

Work for one hour and rest for 10- 15 minutes to relieve fatigue and avoid overwork. Drink more white water, honey water or mung bean soup to expel toxins accumulated in the body. Usually, you can wear a mask when welding to avoid directly inhaling a lot of tin smoke and toxic gases.

But it is best to add tin by spot welding with automatic soldering machine. Personnel can keep a safe distance during the processing of automatic soldering machine, and it is not easy to hurt our eyes. The processing speed is also one or two times that of manual processing.
