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