Dry powder fire extinguisher.
Analysis of responses
As dry powder is neither conductive nor corrosive, it can extinguish fires caused by energized equipment . However, if you are using a dry powder fire extinguisher to extinguish a fire in an electrical appliance, you must first turn off the electrical power before putting out the fire. If the electrical appliance is electrified, it will be dangerous.
In addition to dry powder fire extinguishers, carbon dioxide fire extinguishers can also be used to extinguish fires in electrical equipment. This type of fire extinguisher can be used for electrical equipment with a voltage above 600 volts, but. remember to turn off the power first.
Family Fire Prevention Tips:
1. Warn and warn children not to play with fire, matches, lighters, etc.. Electrical equipment must be used under parental supervision and fires must not be thrown into trash cans or onto flammable and combustible debris.
2. Recognize some fire signs with your children, such as safety exits, escape routes, etc., and tell them where they can't go, what they can't play with, and what objects are dangerous.
3. Teach children to protect themselves in the event of a fire, help them master the basic methods of escaping from a fire, understand the environment around residential buildings and familiarize themselves with escape routes. Teach children to escape quickly in the event of a fire. Never take the elevator and safety stairs. Do not carry personal belongings to ensure your personal safety.
4. After discovering a fire, you are not allowed to extinguish the fire without authorization. YOUmust call the fire alarm telephone number “119” in time. When you call the police, you must give the details. address, fire location, fire materials, fire size, etc.
5. Do not store flammable, explosive and other dangerous objects at home, and do not bring flammable, explosive and other dangerous objects to school.
6. Educate children not to touch gas stoves, appliances, wiring boards and other electrical and fire equipment at home without permission.
7. Do not connect wires indiscriminately at home. Household appliances should be turned off immediately after use. Used electric heaters should be completely cooled before storage.
8. Clean up illegally parked e-bikes and debris in hallways, keep hallways open and developper the habit of “three cleans and three checks” (clean the balcony, aisles and kitchen, and turn off fire, electricity and gas) Good habits.
9. Parents must check at all times whether there are fire hazards in the home and remedy them in a timely manner. Check for safety hazards in electrical wires and appliances. Do not use old or damaged electrical wires and appliances and install smoke detectors in your home.
Generally speaking, when an electrical fire occurs, the power supply should be cut off as much as possible before extinguishing the fire to ensure the safety of personnel.
If the power cannot be turned off in time, common fire extinguishers such as dry powder extinguishers (generally considered insulated below 5000V ), < strong>carbon dioxide fire extinguishers canent be used(generally recognizedIsolate 600V below) to carry out fire extinguishing.
Less common ones like Perfluorohexanone fire extinguishers (under development, perfluorohexanone is not conductive, there are experiments on the Internet to discharge electrical plugs into the perfluorohexanone at room temperature) It can work normally in ketone liquid)
Large-scale fire extinguishing devices and fire extinguishing systems, such as fire extinguishing systems Fire using nitrogen, IG541 and clean gas fire extinguishing agents such as hexafluoropropane and heptafluoropropane, can extinguish actual fires. of.
Finally, let me mention the water-based water mist extinguisher that has appeared in recent years. It is generally claimed that it can put out firesreal below 36Kv. that the water mist particles are ideally dispersed and the droplet size is The principle is that when the distance is small and the distance is large, the insulation is relatively large. That is to say, if you use this type of sprinkler to extinguish real fires, you must ensure that the atomization effect of the sprinkler head is good, otherwise you should not try it easily. After all, there is a certain degree of danger. especially for non-domestic high voltage electricity.
