Web alarm clock for 2:22 a.m.
You are getting ready well before the wholesale fish wharf gates need opening, so a 2:22 am alarm gives you a clear marker while keys, paperwork, and the entry area are checked. Setting it now keeps that early duty separate from the other jobs waiting before 3:00 am.
While preparing to open the wharf gates, check where your browser’s sound is actually going. A pair of headphones left connected can receive the alarm without you noticing, leaving the work area quiet when you expect a speaker alert. Play a quick test sound, disconnect the headphones if they are not needed, and set a volume that can be heard from where you will wait. Keep this page active and the computer awake: if either is shut down, the alarm cannot signal that it is time to open the gates.
At the fish wharf, the background noise before dawn may change quickly as ice boxes, engines, and arriving crews begin to stir. Choose a waiting spot where the 2:22 am signal will not be masked by a nearby motor, then listen again after activity picks up. If you move closer to the gates, take the sounding device with you rather than relying on noise carrying across the compound.
