1-1-9 is a special number that you can call in an emergency when you need help right away. It's like calling a superhero who will come to your rescue when you are in trouble.
Let's say you are playing in the park and you see someone fall off the swings and hurt themselves. You know they need help, but you don't know what to do. That's when you can call 1-1-9 and tell the superhero on the phone what's happening. They will ask you some questions like where you are, what happened, and if anyone is hurt. Then they will send some real-life superheroes like firefighters, police officers, and paramedics to help.
It's important to remember that 1-1-9 is only for emergencies when you need immediate help. If you have a question, want to say hi, or need help with something that is not an emergency, you can call a different number or ask a grown-up for help.
