In the US (I'd assume Europe has a similar thing with different specifics), most fire extinguishers are certified for some or all of three categories of fire: normal, flammable liquid (think grease fire), or electrical. Most extinguishers actually work fine on electrical fires, but it is important to check as a few contain a conductive suppressant (like water) that can cause an electrocution.
- avar 5y agoAn electric scooter is somewhere around 12v-60v. Is it really plausible that electricity will arch from a battery on fire towards the extinguisher?
- theshrike79 5y agoNo. The chemical reaction is just really intense and next to impossible to stop. With an intense lithium-ion battery fire the only thing you can do is calm it down a bit (with a ton of water or sand) and make sure it doesn't spread.
- LargoLasskhyfv 4y agoWhat about the hydroflouric acid if it happens indoors? I wouldn't want to inhale that stuff! I actually thought about what to do when it happens here. Only thing I could think of was to try to put it into a metal bucket which I don't have, only empty paint cans, or baking tray from the oven, and get it out onto the balcony ASAP, if possible at all.
- kayodelycaon 5y agoGrease fires are actually class K. Small ones, like a frying pan, can be extinguished with a class B extinguisher, but if there is enough grease/oil, or it gets too hot, you need something more powerful.
- marcinzm 5y agoActually I believe lithium ion fires are considered flammable liquid and not electric fires. It's a chemical reaction in the battery which isn't making electricity at the time but rather heat. Even then it's not a normal liquid fire since the oxidizer is in the battery rather than in the air.
