I took many precautions in running these tests and checked and double checked every time I energized a line. Watches and rings were taken off hands and I stayed insulated form ground.
Just dealing with our boxes without modifying neither opening them and with non hurted power cables shall always be safe.
Live mains (or using a test tool, with probes), or even opening an amplifier where you have more than 50V DC inside and big caps can be lethal. There are a lot of risks off injuries, includings severe burns, due to high voltages or currents.
The worst I experienced where not shocks (often over years), but a short with probes on 50V 32A. My probes blowed, and I was dazzled/blind for an hour.
One may also fall and so get severly hurted if he gets shocked...
There are specific knowledges, trainings and equipements (helmets, isolated tools, strict procedures, gloves, eyeglasses, isolation pads, ...) for such activities, either with live mains, or high DC (from 50V) and caps or batteries (high to very currents).
