Many posts here, especially from electrical professionals, include warnings about potential for electric shock when working on radios or TVs, but everybody seems to have different recommendations to ensure safety.

I've adopted a few simple rules to avoid errors of forgetting the state of the set, such as when interrupted or distracted.

1. Any set on the bench is only plugged in via a hair-trigger circuit-breaker.

2. I always leave the set's power switch permanently in the ON position, and any dial or pilot lamp active, so there is an automatic visual indication if AC supply is present.

3. Switching on/off for test purposes is done from the power-point, and the set's AC supply plug is normally pulled out when not under test.

One hand in your pocket while poking around with a voltmeter probe in a live chassis. Objective is to avoid taking a shock current across your heart.
