Sparkresistant tools are used to eliminate the chances of accidental fires or explosions in potentially combustible or explosive environments. They resist the sparks that a standard tool could potentially create when striking hard surfaces. The use of spark resistant tools is essential in many industrial applications such as petroleum and chemical manufacturing, spray booth operations, the marine industry, the mining industry, the paper industries, or any location where flammable vapours or combustible residues are present. Aluminiumbronze spark resistant safety tools are manufactured to 25HRC and offer a breaking strain of 75 85kgf/mm2.

防火工具用于消除潜在易燃或爆炸环境中发生意外火灾或爆炸的可能性。它们能够抵抗标准工具在打击硬表面时可能产生的火花。在石油化工制造、喷漆房操作、船舶行业、矿业、造纸业或任何存在可燃蒸气或可燃残留物的场所中，使用防火工具至关重要。铝青铜防火安全工具经过25HRC加工，并提供75-85kgf/mm2的断裂应力。

Sparkresistant tools must be maintained with special care. Frequent cleaning/redressing to remove ferrous particles or contaminants, which may impair the sparkresistant properties, is essential.

防火工具必须特别小心地维护。经常清洁/更换以去除可能影响防火性能的铁质颗粒或污染物是必不可少的。
