The TSA has banned cordless curling irons with a gas cartridge, butane, lithium metal or lithium ion batteries from checked bags, restricting them to carry-on luggage, according to the agency. Those cordless curling irons are one of the hazardous items the Federal Aviation Administration says can leak, cause toxic fumes, catch fire or explode.

Cordless hair devices are the latest items to be banned from checked luggage, as reflected in the TSA’s “What Can I Bring?” list. This includes cordless curling irons and flatirons containing gas cartridges, butane-fueled curling irons and flatirons, and gas refill cartridges for these tools.
