Wow, this is terrible and dangerous advice. There are multiple laws that prohibit this, some of which are in place to protect people from danger (such as the high voltages involved or the possible risk of injury to yourself or others) while others are about certification.

The desire to help is absolutely laudable, and I wish it were easier for volunteers to get permission to go and do it, but to go on an Internet forum to wrongly claim that it's already allowed is irresponsible.
