Non sparking Pliers,Copper Long Nose Pliers,Safety Hand Tools

Application: Non sparking tools can avoid rise sparking when be used.Beryllium Copper can prevent magnetic reaction. These tools apply to dangerousenvironment where flammble and conbustible vapors liquid gas is existed such asoil and gas works, petro-chemical plants, explosive manufactories, mines,shipyards, pipeline construction, pharmacy, airport etc.
