Signal for help with three whistle blasts

Grab first

• A whistle that the child can reach
• A safe practice spot with an adult beside the child
• A phone and the route information for the outing

Before you start

• Explain the practice to nearby people so they do not mistake it for a real emergency. Do not blow close to anyone's ears.
• If waiting for rescue, stay put unless there is an immediate threat to life.

The steps

1. Agree what the signal means

   Explain that three blasts ask for help. Check that the child can reach the whistle without emptying a backpack.

2. Blow a group of three

   With the adult beside the child, blow three distinct blasts. Count them on fingers instead of rushing into one long noise.

3. Pause and repeat

   Stop to listen and rest. Then repeat the group of three, rather than blowing continuously or using all your energy shouting.

4. Connect the signal to the plan

   For a real emergency, call 911 if you have reception. Share the trail, last known location and other requested details. While waiting for rescue, stay put unless remaining there threatens your life.

Common mistakes

• Keeping the whistle somewhere the child cannot reach.
• Blowing without pauses to listen or conserve energy.
• Wandering to try to find a louder place after calling for rescue.

Practice together

Start with finger signals instead of sound: three fingers, a listening pause, three again. Then do one announced whistle practice with the adult right there. Ask the kid to point to where the whistle will go before the next outing.
