You're not likely to encounter fires the next time you visit Walt Disney World, but be prepared to evacuate if you hear this code. A cast member uses the term ?Signal 70? when reporting a lost child.

At Disney Parks, the term "lost child" is never used over the radio or in front of guests to avoid causing panic. Instead, Cast Members use "Signal 70." When a child is separated from their party, they are often referred to as a "lost adult" by staff—a psychological trick to keep the child calm by making them feel like they are the "detective" looking for their parents rather than the one who is lost. In 2026, Disney's protocols remain the industry gold standard; once a Signal 70 is called, the child is escorted to a Baby Care Center, where they are supervised by specialized staff until the "lost adults" are located. Most guests will never even realize an incident occurred, as the "Signal 70" is a quiet, high-value code that triggers a massive, coordinated search effort behind the scenes while maintaining the park's magical atmosphere.
