Well, that depends. If the electricity is still turned onthen we would use a CO2 extinguisher. If it is de-energized, then it would be treated as a normal fire, and you could put it out with a hose stream. In a perfect world though, CO2 is the best because it does no more damage to whatever is on fire, whereas water corrodes and shorts wiring.
Extinguishers with a Class C rating (C can be used on Currents)
It is important because fire equipment that has not been rated for electrical fire use may conduct electricity and electro-fry the user, whereas equipment such as electrically rated fire extinguishers (class C) will not conduct electricity, therefore keeping the operator safe. If you want more information on fire extinguishers such as different types and which instance to use them I have provided a link with this post.
FIRE extinguishers are used to put out fire.
They are idea for dealing with wood and paper fires. Never use water on live electrical or petrol fires
Foam spray extinguishers are not recommended for fires involving electricity, but are safer than water if inadvertently sprayed onto live electrical apparatus.
Yes, fire extinguishers can be refilled by trained professionals to ensure they are ready for use in case of a fire emergency.
Hi There Around any electrical fires you must always avoid any liquid base Fire Extinguishers. The most effective Fire Extinguisher to use in that case of a microwave or any electrical appliance use a Carbon dioxide Fire Extinguisher.
Anything other than water can be used on an electrical fire. These are often indicated on fire extinguishers as Class ABC or BC or even just C, where class C refers to fires caused by energized electrical conductors.
It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
Fire extinguishers!!
Some fire extinguishers use dry chemicals and some use a foam to extinguish flames. Some fire extinguishers actually still use water, but they're only for use on smaller fires. Others use a dry chemical, mostly sodium bicarbonate, or Carbon Dioxide.
Fire extinguishers should be recharged annually to ensure they are ready for use in case of an emergency.
