Bukit Batok Flat Catches Fire After PMD Explodes; Residents Rush To Help Before SCDF Arrives

In the early hours of Thursday (18 Jul), a fire broke out on the 26th floor of Block 293D in Bukit Batok.

The Singapore Civil Defence Force (SCDF) responded to the fire at 12.40am and successfully put it out. Their Facebook post stated that the cause of the fire was unknown.

However, a member of parliament, Mr Murali Pillai revealed that the fire was caused by 2 e-scooters an hour before SCDF’s post. In Mr Murali’s Facebook post, he thanked residents for their help.

E-scooters caused Bukit Batok fire

Unfortunately, an e-scooter exploding isn’t uncommon. Just last month, an e-scooter exploded and a man suffered 80% burns.

This time, the fire originated from 2 e-scooters. The scooters probably exploded, causing the unit to be set ablaze.

Residents rushed to help

Before the SCDF even arrived, the unit was already “heavily smoke-logged” from the fire.

However, instead of panicking, community volunteers of Zone 12 Residents Network decided to help.

When the police ordered the evacuation of over 70 residents, they opened the Residents Network Centre to house the affected parties.

A video even showed residents helping the SCDF personnel with a fire hose when they arrived.

Everyone was safe
Thankfully, the first-responders, SPF and SCDF’s brave actions resulted in 0 fatalities.
Firefighters from the SCDF managed to break into the smoke-logged unit with breathing apparatus and put out the fire with 2 water jets.

While putting out the fire, they rescued a man and woman from the unit before they were too seriously injured. The man suffered burns while the woman inhaled too much smoke.

Guidelines to charging your PMDs

As for personal mobility device (PMD) riders, you can follow these guidelines to avoid similar accidents.
  • Charge your PMD away from flammable material
  • Don’t charge your PMD immediately after using
  • Don’t leave the battery charging even after it’s full — especially overnight
MS News hopes that all PMD riders will follow these guidelines properly, so there will be fewer of such incidents. We also wish the injured a swift recovery.

Seriously, a large size lithium battery is a danger. Lithium is a volatile material.

A smartphone has a smaller battery, there are safeguards on both the hardware and software to prevent overcharging.

Yes, Lithium Ion Polymer (or Lipo) batteries are not to be messed with.
http://thedronegirl.com/2015/02/07/lipo-battery/

1. Never charge, discharge, use, or store a damaged or puffy LiPo battery. Immediately follow proper disposal protocols.

2. Avoid purchasing used LiPo batteries. You never know what the previous owner did with them and they could already be badly damaged. “LiPo Battery Like New, Used Once” is usually a scam and should be avoided.

3. Always use a proper LiPo battery balance charger/discharger when charging and discharging your LiPos. It is crucial that all cells in a LiPo battery maintain the same voltage across all cells at all times. If the voltages across the cells deviate too much from each other (5mV ~ 10Mv), the battery can become unstable and dangerous. (Unless it’s a single cell LiPo, in which case you do not need to worry about cell balance).

4. Always use a fire proof LiPo safety bag, metal ammo box, or other fire proof container when you are charging, discharging, or storing your LiPo batteries. While LiPo fires are rare, they can happen incredibly quickly and can do a lot of damage. All it takes is an internal short circuit to set the battery off. There is no way to predict when it will happen. It does tend to happen more often when batteries are fully charged, being overcharged, or while being discharged, but it can happen to any LiPo at any time. Never fill the container to capacity with your batteries, always follow manufacturer recommendations on LiPo bags for how many mAh’s it can safely contain. It’s ALWAYS worth investing in an (under $10) explosion-proof LiPo bag or ammo can.

5. Do not use your flight case/travel case for long term LiPo storage. The foam and plastic in these cases can help spread a LiPo fire. Always use a fire proof container such as a metal ammo box or fire proof safe for storage.

6. Never leave your LiPo batteries charging while unattended. If a battery starts to become puffy, smoke, or catches fire you need to be able to immediately handle the situation. Walking away for even just 5 minutes can spell disaster.

7. A LiPo fire is a chemical fire. Always keep a Class D fire extinguisher nearby your battery charging/discharging and storage area. The battery charging/discharging and storage area should be free from any materials which can catch fire such as wood tables, carpet, or gasoline containers. The ideal surface for charging and storing LiPo batteries is concrete or ceramic.

8. Never overcharge a LiPo battery. Typically a full charge is 4.2v per cell. Never “trickle” charge a LiPo battery.

9. Never discharge a LiPo battery below 3.0v per cell. Ideally you never want to go below 3.2v per cell to maintain a healthy battery. 2.9v per cell and lower is causing permanent damage.

10. Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again.

11. Always store your LiPo batteries at room temperature. Do not store them in a hot garage, or in a cold refrigerator. Even though a cold battery has less chemical reaction taking place which can prolong its lifespan, taking a battery out from a cold fridge can cause condensation to occur on the inside of the battery, which can be very dangerous.

12. Always remember that heat is the number one enemy of LiPo batteries. The hotter your batteries get, the shorter their lifespan will be. Never charge a battery that is still warm from usage, and never use a battery that is still warm from charging.

13. Depending on how they are used, most LiPo batteries typically do not last longer than 300 charge cycles. Leaving them around on a full or depleted charge all the time, running them completely dead, or exposing them to high temperatures will shorten this lifespan dramatically.

14. LiPo batteries do not work well in cold weather. The colder it is, the shorter your run times will be due to the slowing down of the chemical activity within the battery. If it is below 14F (-10C), LiPo usage is not recommended at all. Your battery could cause your R/C vehicle to suddenly fail without warning in these temperatures.

15. Always pack your LiPo batteries in your carry-on bag and never in your checked baggage when traveling on an airplane. It’s the law.
