Major airlines will be stocking planes with fire-containment bags, amid reports that certain smartphones can overheat and burst into flames, in a move meant to prevent devices from exploding aboard flights and in airports.

Delta plans to supply its entire mainline fleet with fire-containment bags by the end of 2017, according to the Wall StreetJournal. The airline joins Virgin America Inc. and Alaska Air Group Inc., which began doing so earlier this year, the newspaper said.

The safety effort comes as Samsung found its Galaxy Note 7 smartphones were found prone to catch fire.

There were 23 recorded incidents of involving overheating, fire, smoke or an explosion on planes and in airports this year, the WSJ reports, although the causes of each incident is unclear.
