How to use the online alarm clock
Before handing the evacuation drill over to a colleague, set the alarm for 11:07 am and pass on the remaining details clearly. That gives them a definite cue to gather the office team, check the route and be ready well before 12:00 pm, without relying on someone watching the clock during the handover.
Because the signal will matter after responsibility has changed hands, test its sound now while both people can hear it. Check that the volume is noticeable in the office and that the browser has permission to play audio. Keep the alarm page open and the computer awake: otherwise the evacuation drill alert may not sound, leaving the colleague without the cue they were expecting. A brief test also confirms which person will respond when 11:07 am arrives.
Once the drill is assigned, leave a sensible gap before the next commitment that morning. Use the time after 11:07 am to return equipment, record any problems with the route and let staff settle before lunch-hour plans begin. If another meeting or task follows later that day, note its start time beside the drill details so the handover includes enough room for both activities.
Common questions
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
