Nonsparking tools can avoid rise sparking when were used, Beryllium Coppercan prevent magnetic reaction. These tools apply to dangerous environment whereflammable and combustible vapors liquid gas is existed such as oil and gasworks, petro-chemical plants, explosive manufactories, mines, shipyards,pipeline construction, pharmacy, airport etc.
