Set the timer to 53 seconds

Online timer for 53 seconds

Guide your child through a 53 seconds check of the whistle kept in your household emergency kit. While the timer runs, have them find the whistle, inspect it for cracks or dirt, and give one short blow outdoors without putting their fingers over the opening. You can watch how they handle it and explain that the whistle stays with the kit rather than becoming an everyday toy.

During the whistle check, your phone can remain silent so its sound does not compete with the signal you are listening for. Keep the screen visible while your child follows your directions, or rely on vibration if you need to look at the whistle closely. This is especially useful in a shared home or classroom, where a loud timer alert could distract others from an earthquake-preparedness activity.

After your learner returns the whistle to its emergency-kit pocket, decide whether another round would add anything useful. For an immediate repeat, reset the countdown and swap roles or test a second kit instead of asking for repeated blasts from the same whistle. A brief pause also gives you time to confirm that the mouthpiece is clean and that everyone knows where the whistle belongs.
