AFTER FIRE KILLS 3, NYC OFFICIALS SAY RETAILERS, DELIVERY APPS MUST DO MORE TO ENSURE E-BIKE SAFETY

New York City officials say retailers and food delivery companies must do more to halt the proliferation of unsafe e-bike and e-scooter batteries, after a fire blamed on an electric scooter's lithium ion battery killed three people over the weekend.

"There is blood on the hands of this private industry," Fire Commissioner Laura Kavanagh said at a news conference Monday in front of the charred remains of the Brooklyn row house where the early Sunday blaze killed Albertha West, 81, her son Michael West, 58, and her grandson Jamiyl West, 33.

Fire officials said the fire broke out on the ground floor of the building. "It's extensively damaged, Kavanagh said, adding that the battery that sparked the fire was for a "scooter of some kind."

The city has seen hundreds of fires linked to the lithium ion batteries that power electric bikes and scooters in the last few years. City officials have blamed off-market batteries and chargers that don't meet safety standards for many of the fires, and they have lobbied the federal government to strengthen regulations governing the sale of e-bikes and batteries.

But Kavanagh said companies also have a role to play too.
