So since this topic is here to stay, I think instead of debating who is right and wrong, I think we should be prepared if there is something bad happening around us. I used to be from the Navy so I have learned some basic fire-fighting knowledge. I never fight a real fire before, luckily. So all the stuff I mention is from my understanding and with the help from google. At least 34 cases of PMD-related fires this year. There have been at least 34 cases of fires involving personal mobility devices (PMDs) so far this year, with two incidents over the last two days.

You can see the video here. and for a small lithium-ion battery, it can already cause such big damage, imagine you have like 10kg worth of lithium-ion battery. How to extinguish a lithium-ion battery? To prevent me from "oversteer", let's dive straight to the topic. Despite their name, lithium-ion batteries used in consumer products do not contain any actual lithium metal. For lithium fires, only a CLASS D COPPER POWDER EXTINGUISHER is recommended. The minimum equipment required includes eye-protection, respirator, rubber gloves, etc. If other combustibles nearby catch fire as well as a result of the lithium fire, then we need to use appropriate extinguishing agents to douse the secondary fires. Needless to mention, it is important to address each type of fire with the appropriate extinguishing. So as you can see from the chart, Class D fire is to tackle combustible metal. It is very expensive to actually keep a class D fire extinguishers at home compared to the dry powder extinguishers. So is there any other way to put out class D fire? since Li-ion contains very little lithium metal that reacts with water. Water also cools the adjacent area and prevents the fire from spreading. Research laboratories and factories also use water to extinguish Li-ion battery fires. But I think this part is subjective. If there is smoke from the lithium-ion battery or there is an initial flame, I think water will be useful if it has already ignited, I don't think it will help. @carbon82 can help me with this. haha. Should I get one Class D fire extinguishers? Some of you might not have bought a fire extinguisher before. A normal dry powder ABC extinguisher is about $25 at lazada. So who will want to buy $620 dollar of extinguisher and stand by? If our government can invest 7 million on the return scheme of PMD, I think they should consider having extinguisher mounted at all HDB staircase or something. And I think it is good that maybe whoever is buying and registering a PMD, they need to go through a 1-hour fire fighting session or something. If they carry the risk, they must minimize the risk too. make the buying process a bit more troublesome, so those young punk will find it a hassle to own one. That's my thoughts. I never win TOTM before thou. 🤣🤣🤣
