| 哪种类型的灭火器被评为D类灭火器？ Which type of fire extinguisher is rated as class D fire extinguisher? 首先，D类火灾不能简单地用水或任何灭火剂扑灭。水与可燃金属相互作用，加剧了火势，增加了热量并扩散了熔融金属。 First of all, class D fire cannot be put out simply with water or any fire extinguishing agent. Water interacts with combustible metals, intensifies the fire, increases heat and diffuses the molten metal. 因此，必须仅使用D类灭火器灭火可燃金属火。扑灭这些大火的最佳方法是窒息并消除氧气元素。该剂还有助于吸收燃料中的热量。 Therefore, only class D fire extinguishers must be used to extinguish combustible metal fires. The best way to put out these fires is to suffocate and eliminate oxygen. The agent also helps to absorb heat from the fuel. 迄今为止，唯一的D类灭火器是干粉灭火器。所使用的粉末剂可以是粉末状石墨，颗粒状氯化钠或铜基粉末，它们均能有效地将燃料(点燃的可燃金属)与氧气分离。 So far, the only type D extinguisher is dry powder extinguisher. The powder used can be powdered graphite, granular sodium chloride or copper based powder, which can effectively separate fuel (ignited combustible metal) from oxygen. 干粉灭火器对D类火灾有效，但对其他任何类型的火灾均无效。 Dry powder extinguishers are effective for class D fires, but not for any other type of fire. 重要的是，那些在可燃金属上工作的人员必须了解D类灭火器的独特特性，以及如何(以及何时)正确，安全地操作D类灭火器。 It is important that those working on Combustible Metals understand the unique characteristics of class D extinguishers and how (and when) to operate them correctly and safely. |
