NEW YORK (BRAIN) – Four fires triggered by e-bike lithium-ion batteries on Thursday prompted the FDNY to issue a statement later on its Twitter account about the dangers of improper charging and storage.
The tweet came after the FDNY put out the fires – three in Manhattan and one in Brooklyn – that injured a dozen people. FDNY said lithium-ion fires were the cause of four deaths last year.
“If using a lithium-ion battery, follow the manufacturer’s charging and storage instructions. Always use the manufacturer’s cord and the device-specific power adapter. If battery overheats , please stop using it immediately. See more at http: // fdnysmart. org, “the tweet read.
According to the Daily News, a three-alarm fire was reported in Brooklyn at a home in the Kensington section around 4.00 a.m.. More than 100 firefighters took two hours to control the fire. Seven people were treated for injuries.
A third-floor fire in a nine-story apartment building occurred when a lithium-ion electric motorcycle battery exploded at about 7 am. One resident was treated for smoke inhalation. Later Thursday, firefighters responded to East Harlem when an e-bike caught fire, which spread to a parked vehicle. No injuries were reported. A fourth fire was reported at 6:30 am on the fifth floor of a six-story building in Washington Heights where a lithium-ion battery exploded on an e-bike. Four people were detained in hospital.
Earlier this month, an unsupervised charging e-bike battery at a bike shop in South Florida caught fire and destroyed the interior and much of the inventory, but no injuries were reported.
Lithium-ion batteries, especially those flagged on low-cost e-bikes, can be a fire hazard and should never be left unattended, e-bike experts say. Human Powered Solutions has published Secure Lithium-Ion Battery Storage and Charging Procedures for the eBook Store.
