Read the quoted text. It's saying something is dangerous because of the nature of the electrical system, rather than it's voltage level. I brought up 120VDC to show the misdirected statement about danger.

So why did you say "DC"? Why not just say "With low voltage, the most that can happen would be a hot wire causing a burn in the event of a short. Not really much else could happen."
Your incomplete and off-target statements can be misleading.
