The president of the largest flight attendant union wants the FAA to ban e-cigarettes from planes because their lithium-ion batteries could be a fire hazard.
In 2016, the FAA banned the Samsung Galaxy Note 7 smartphone due to its lithium batteries starting fires.
"A lithium ion battery fire on a plane can be catastrophic," Sara Nelson, president of the Association of Flight Attendants, told CBS News transportation correspondent Kris Van Cleave.
Nelson added that flight attendants have become firefighters on planes, and the FAA needs to do more.
Regulation requires that e-cigarettes, vape pens, and spare batteries must be transported in carry-on bags.
