National Fire Prevention Week focuses on safe battery charging

You may have seen some of the more alarming video footage: a door blown off a garage after an intense fire caused by a scooter left charging; flight attendants gathered around a smoking overhead bin midflight because a cellphone was left on a wireless charger; multiple businesses damaged by fires that started when a charging battery ignited overnight.

Increased use of lithium-ion batteries in devices such as cell phones and laptops, as well as tools, toys, e-bikes and scooters, has led to an increase in fires.

That is why this year's National Fire Prevention Week theme is "Charge into Fire Safety: Safe Charging Is a Superpower."

Clinicians at The University of Texas Medical Branch (UTMB Health) have seen the consequences of fires and explosions involving rechargeable batteries.

"When a lithium-ion battery fails, the resulting injury can be serious. These incidents can expose patients to intense heat, flames, and, in some cases, explosions, resulting in significant burn injuries that may require specialized treatment and a lengthy recovery," said Carlos Jimenez, MD, director of the UTMB Health Blocker Burn Unit. "Many of these injuries are preventable, which makes education about safe charging and battery use especially important."

Simple steps that can prevent fires

The Fire Prevention Week campaign focuses on the simple steps people can take to charge devices safely. Rechargeable lithium-ion batteries store a large amount of energy in a small space. If they are damaged or charged improperly, they can overheat, start a fire, or even explode.

"The way you charge your lithium-ion battery devices can make a difference in helping prevent home fires," Jimenez said. "It comes down to using simple habits each time you plug in."

• Use the cord and charger that came with your device, or one approved by the manufacturer. Using the wrong charger can damage the battery and increase the risk of fire.
• Charge devices on a table, desk, or other hard, flat surface. Do not charge them on beds, couches, or under pillows. Devices and chargers produce heat during normal charging. Soft surfaces can trap heat and block airflow, which can cause a battery to overheat.
• Stop using your device if it feels very hot, starts to swell, is smoking, or has a strange smell. These are warning signs that the battery may be damaged or failing.
• Unplug your device when it is fully charged. Do not leave it plugged in longer than necessary. Leaving a device plugged in too long can increase heat and stress on the battery.
• Charge larger items such as e-bikes, scooters, and power tools outside and away from exits. These batteries are larger and store more energy. If they fail, fires can grow quickly and spread.
• When on a plane, keep your device where you can see it while charging. Do not charge devices in overhead compartments. Do not charge e-cigarettes or vapes on a plane. If a battery overheats or fails, it is important for the flight crew to respond quickly.

Blocker Burn Clinic provides specialized care

Jimenez said people should seek medical care for burns involving the face, hands, feet, eyes, ears, or genital area; burns larger than the palm of the hand; deep, blistered, or charred burns; burns that wrap around an arm or leg; or burns that show signs of infection or worsening after two to three days.

For major burn injuries, seek immediate medical attention at the nearest emergency department.
