Atlanta's airport has begun warning travelers of the dangers of "shoe entrapment" on escalators.
The safety campaign follows a recent rash of injuries on escalators at Hartsfield-Jackson International Airport. A spokesman says at least three children have been injured in the last two months after escalators gobbled up their flip flops or Crocs, a rubber clog-like shoe.
The U.S. Consumer Product Safety Commission has documented 77 soft shoe entrapments on escalators since January 2006. The safety agency issued a warning in May.
Malls, subway stations and other airports have also started posting warning signs after a surge of incidents last year.
