I can't believe the NEC (National Electrical Code) isn't stricter about residential circuit breaker panels. I've lived in three houses, all built in the 1990s, and the labeling of the breakers is SO iffy.
For starters, there is the usual half-literate scrawl and uncertain abbrevs. for the various rooms and locations. Worse yet is the fact that they are inaccurate and incomplete. On top of all this, the label is typically separate from the breaker switches. In some cases, there aren't even line numbers to match up. So if you find the DR lights you need to turn off are 6 rows down on the label right-hand side of the label, you have to count 6 down on the right hand side of the panel. Much better if there were a label next to each breaker switch.
Finally, there is no provision for lock-out. Okay, realistically, it is hard enough to get building maintenance personnel to lock-out regularly, homeowners are unlikely to do so. But they could at least have a mailbox-style flag to set, to indicate that breakers have been intentionally turned off.
