Set the alarm for 3:48 p.m.

Web alarm clock for 3:48 p.m.

You are midway through another task when the 3:48 pm alarm tells you to break away and conduct the earthquake preparedness drill. That leaves the session close enough to 4:00 pm for participants to connect the alert with a clear practice routine, while still giving you time to guide everyone through the planned response.

Because the drill depends on a signal that people can recognise, test the alarm before the session begins and listen from the part of the room farthest from your phone. Set the volume, choose a distinct tone, and confirm that the display shows 3:48 pm. Keep this browser alarm active and the phone awake: if either is shut down, the earthquake preparedness drill may begin without its cue.

As the afternoon light shifts across the room, position your phone where glare will not hide the alarm controls or make you keep checking a bright screen. Lower the display brightness to match the indoor light, enlarge the time if your browser allows it, and place the phone within a quick glance of your drill materials. A short look should be enough to confirm the alarm without pulling your attention away from the group.
