Non-sparking tools are made of materials that do not contain iron (non-ferrous metals) and therefore the risk of a spark being created while the tool is in use is reduced. Non-sparking tools protect against both fire and explosion in environments that may contain flammable liquids, vapors, dusts or residues. When working in confined spaces and areas where flammable gases or dusts are present, using a non-sparking tool is the best practice. Common materials used for non-sparking tools include brass, bronze, copper-nickel alloys, copper- aluminum alloys or copper-beryllium alloys. Beryllium alloys are less favorable due to the potential toxicity of beryllium dust. […]
