The Tennessee teen, four of her family members and three other teenagers were sitting aboard the train Saturday when a “fireball” shot at her from one of her fellow passengers, Orlando police said.
“It was just a weird, freak accident that unfortunately caused injuries to two people,” police Lt. Dan Brady told The Orlando Sentinel. “It wasn’t a big explosion but was definitely enough to scare everyone who was in that cab of the train.”
She sustained moderate burns to the right side of her face and was taken to Arnold Palmer Children’s Hospital for treatment, police said in a statement.
Authorities believe the e-cigarette’s owner was also injured in the explosion but fled the scene with the other teens before they were notified of the incident at 3:30 p.m.
Police said the device believed to be responsible for the explosion was stored in the rider’s pocket at the time.
The train, which connects Universal Orlando park goers to Universal’s Island of Adventure theme park, was temporarily shut down, the Sentinel reported.
Explosions caused by e-cigarettes are rare but the consequences can be severe.
The reason behind this is the devices’ lithium-ion batteries, which can occasionally overheat, causing it to short circuit and catch fire, according to a Live Science report.
Cellphone devices that use the same batteries have also been known to explode. In September, Samsung ordered a recall of their Galaxy Note 7 smartphones for this very reason.
There have also been reports of iPhones catching fire and burning users.
