What are the safety hazards when traveling without turning off the power supply at home?

If it is an old community, the circuit will be somewhat aging. What should I do if the gadget needs to be connected to light a fire? Igniting is more difficult than any other fire.

To put it bluntly, if you want to be lucky, you have to have someone at home. Ha ha.
