Set the alarm clock for 4:03 am

How to use the online alarm clock

Pause your kit check at 4:03 am and set the alarm before the next task absorbs your attention. It gives you a clear point to stop what you are doing, collect the last essentials and leave for your shift at a London fire station. With 5:00 am still ahead, the alert can mark the moment when preparation ends and the journey begins.

Your fire-station departure depends on the alarm surviving while you finish getting ready, so check how long the phone or computer remains awake. A screen that dims is not necessarily a problem, but a device that enters sleep may suspend the browser before 4:03 am. Because this alarm needs an active browser, it cannot interrupt preparations for the shift if the browser has been closed or the device has fallen asleep. Keep power connected where practical and use a separate alarm as backup when being late would affect the crew.

Before heading towards the station during a warm London night, avoid leaving an air-conditioned room and immediately rushing outside in heavy kit. Set out water and any outer layer beside your keys, then allow a moment to adjust to the temperature after the alarm sounds. At this hour, cooler corridors or vehicles can make the outdoor heat feel sharper than expected.
