1. However, refined naphthalene is a toxic solid organic matter. Inhalation of high temperature steam will be harmful to human health. Both carbon dioxide extinguishers and foam extinguishers may be dangerous, so dry powder extinguishers should be used.

2、根据火灾种类，实验室内配置的灭火器的适用范围：. 注：. 新型的添加了能灭B类火的添加剂的水型灭火器具有B类灭火级别，可灭B类火灾；. 仅适用于带电的B类火灾；. 扑灭极性溶剂火灾，应使用抗溶泡沫灭火器；.

2. According to the type of fire, the applicable range of fire extinguishers configured in the laboratory is: Note: The new type of water-based fire extinguisher with additives that can extinguish Class B fires has a Class B fire extinguishing level and can extinguish Class B fires Only applicable to live Class B fires To extinguish polar solvent fire, use insoluble foam fire extinguisher

3、问题二：危险货物精萘着火时，宜用什么灭火 橡胶属于一般性易燃物，着火时，用普通的泡沫灭火器、干粉灭火器、1211灭火器、灭火器等都可以，还可以用砂子、细土、水，都可以有效灭火。 问题三：粉状易燃物着火如何扑灭

3. Question 2: When the refined naphthalene of dangerous goods catches fire, what kind of rubber should be used to extinguish the fire is a general combustible. When the fire catches fire, ordinary foam extinguishers, dry powder extinguishers, 1211 extinguishers, fire extinguishers, etc. can be used, and sand, fine soil, and water can also be used to effectively extinguish the fire. Question 3: How to extinguish the ignition of powdered flammable substances

4、橡胶属于一般性易燃物，着火时，用普通的泡沫灭火器、干粉灭火器、1211灭火器、灭火器等都可以，还可以用砂子、细土、水，都可以有效灭火。

4. Rubber is a general flammable material. In case of fire, ordinary foam extinguishers, dry powder extinguishers, 1211 extinguishers, fire extinguishers, etc. can be used, and sand, fine soil, and water can also be used to effectively extinguish the fire.

5、你这个问题有些问题啊,都是高价化合物,其中的硫元素和氮元素都无法再被氧化,明显不可燃.而精萘属于有毒的固态有机物,吸入高温蒸汽会对人体有害,无论是二氧化碳灭火器还是泡沫灭火器都有可能产生危险,应该使用干粉灭火器.

5. There are some problems with your question. All of them are high priced compounds, and the sulfur and nitrogen elements can no longer be oxidized, which is obviously nonflammable. Refined naphthalene is a toxic solid organic matter. Inhaling high temperature steam will be harmful to human health. Whether it is a carbon dioxide extinguisher or a foam extinguisher, it may be dangerous. Dry powder extinguishers should be used

6、危险货物精萘着火时，宜用__雾状水__灭火。 追问. 百度是两种答案，一个泡沫灭火剂，一个雾状水，到底哪个是对的. 追答. 灭火方法：灭火剂：雾状水、二氧化碳、砂土。 切勿将水流直接射至溶融物，以免引起严重的流淌火灾或引起剧烈的沸溅。

6. When the refined naphthalene of dangerous goods catches fire, it should be used__ Misty water__ Fire extinguishing. Interrogate Baidu has two answers, one is foam extinguishing agent, the other is fog water, which is right Follow up Fire extinguishing method: Fire extinguishing agent: Misty water, carbon dioxide, sand. Do not spray water directly onto the molten material to avoid causing serious flowing fires or severe boiling splashes.
