The shift register layout we describe is intended or use with a relay board like the Keyes 5v board.

Those boards include opto-isolators and the other necessary circuitry to be driven by a Raspberry Pi or Arduino. The relays can handle up to 10A AC or DC.
The reset pin of the shift registers is connected to a GPIO pin on the Pi if you check the diagram. There are users who have been running this type of setup for years without a problem.
