When rotating equipment and electrical components in power plants catch fire, carbon dioxide extinguishers and sand can be used to put out the fire. Answer: Yes. The fire-extinguishing range of carbon dioxide includes use in extinguishing fires involving electrical equipment with voltages below 600 volts, precision instruments, books, and archives. It is also suitable for putting out fires involving small amounts of oil, gases, and certain substances that cannot be extinguished using water. When using a carbon dioxide fire extinguisher to put out electrical fires, if the voltage is over 600 volts, the power supply must be turned off first before extinguishing the fire.
