Take charge of your safety: prevent lithium-ion battery fires

You may not always see them, but lithium-ion batteries power our lives every single day. They can be found in rechargeable devices like cell phones, laptops, power tools, vacuums, e-bikes, e-scooters, wheelchairs, hoverboards, lawnmowers and electric vehicles (EV). As the weather warms up, the risk of lithium-ion battery fires also increases, with increased use of various items. Mississauga Fire and Emergency Services (MFES) is encouraging residents to learn more about how to prevent lithium-ion battery fires and what to do in an emergency.

Lithium-ion batteries are widely used today because of their ability to store a large amount of energy in a relatively small space. Think of a lithium-ion battery as a tiny container holding energy, like a balloon filled with air. However, if something goes wrong and all that energy is released suddenly and rapidly, it can be compared to a balloon popping. This can cause the inside of the battery to rapidly heat up, leading to a fire that can be difficult to extinguish. When a battery undergoes a “thermal runaway,” it behaves like a snowball effect, where the temperature keeps rising, and the risk of catching fire, increases. In addition, there are significant risks to the user from toxic smoke and gases released during a fire, which is why firefighters need to be present at the scene of a lithium-ion battery fire.

Use the C.H.A.R.G.E. acronym, to stay safe:

C – Choose certified products

Most lithium-ion battery fires are caused by products that come with poorly made batteries, aftermarket and heavily discounted products or incompatible chargers. When purchasing lithium-ion battery-powered products, purchase them from reputable manufacturers and stores and be sure to purchase products that are certified by a nationally recognized testing laboratory such as CSA, UL or ETL.

H – Handle with care

• Follow the manufacturer’s instructions and use the charging equipment that came with the product.
• Store batteries away from extreme heat or cold, or anything that can catch fire.
• Never charge devices while you are sleeping.
• Never block an exit when charging the battery.
• Stop charging the battery when it is fully charged.

A – Always be alert for warning signs

• Handle and charge batteries with care.
• Check batteries regularly for damage, swelling, hissing or popping noises, strange odours, excessive heat or smoke.
• If you notice any of these warning signs, stop using the device immediately, get to safety and call 911.

R – Recycle batteries responsibly

• Dispose of old or damaged batteries at the nearest Hazardous Community Recycling Centre (CRC).
• Never dispose of lithium-ion batteries in the regular trash.

G – Get out quickly

• Know the warning signs to look and listen for.
• Follow your home escape plan, leave the area immediately and call 911.

E – Educate others about battery safety

• Educate others about taking C.H.A.R.G.E. of battery safety.

Drive a hybrid or electric car? Pay attention to the following tips:

• Be aware that battery fires may initially show from under the vehicle.
• EV’s are quieter than gas cars. Double check to see if the vehicle is turned off at home, especially when parked in the garage.
• Firefighters require large quantities of water to fight EV vehicle fires. Do not attempt to control the fire – it can produce heat and toxic gases even after submerging the battery in water. Always dial 911 and remove yourself from the area.

Lithium-ion battery products are used by all ages including children, teenagers, and seniors, so its important to be smart about your usage and take charge of safety.
