A private Rhode Island university has banned hoverboards on campus after federal officials announced a safety investigation amid reports that the self-balancing scooters are exploding. The Newport Daily News reported that Michael Caruolo, director of safety and security at Salve Regina University, issued an order Monday banning hoverboards in dorms, academic buildings, and elsewhere. Caruolo said reports of hoverboard fires prompted him to issue the ban, but said the university will reconsider if the fire danger is eliminated. Reports have indicated the boards' lithium ion batteries may be causing the explosions and fires. A Consumer Product Safety Commission spokesman said it was examining the safety of the entire product line.
