After hours
Someone answers. A journeyman rolls.
Outages, water in a closet, generator fail-to-start. Existing customers first. New callers taken when we have a body. We will say so on the phone.
Call (865) 555-012301
Call the shop line
It rings to the on-call journeyman after 17:00. Do not email an outage.
02
Say what failed
Building, floor, last known state. If water is in the gear, say that first.
03
Meet them at the dock
Have access and, if you can, the one-line. Temporary power if the repair is larger than tonight.
