[0002] Protective devices for sheet metal cutting are devices used to protect operators from sparks, flying metal and heat radiation generated during the cutting process. Sheet metal cutting protective devices mainly include personal protective equipment such as protective masks, protective glasses, protective clothing, earplugs, as well as protective covers and protective baffles on mechanical equipment. These devices are designed to reduce the risk of injury to operators during sheet metal cutting and ensure their safety;
