We often hear that welders are blinded by arc light. In fact, we still need to emphasize the importance of protective masks. It can not only protect eyes from blinding, but also prevent eye burns, welding slag, and arc light radiation. And wearing it will not affect the field of vision during work.
Similar to welding masks, protective glasses and protective masks are a kind of personal protective equipment, mainly to protect the eyes and face from dust, smoke, metal and gravel debris and chemical solution splash damage, some special The protective glasses or masks can also prevent the radiation of electromagnetic waves such as ultraviolet, infrared and microwave on the human face.
In the past, many factories and workers did not wear goggles, helmets, anti-smashing boots, etc. It was only after the accident that everyone realized their importance.
The difference between protective glasses and protective masks is that protective glasses can only protect the eyes; while protective masks can protect the entire head of the human body.
In any case, protective gear must be worn for your own sake, so why bother with your own health and "just in case".
