Follow-up from TV show on water shutoff

Recently saw on TOH a device that would shut off the water supply to a hot water heater via a float in the drip pan below in the event of failure. My question is even though the water supply is off, the contents of the water heater could drain leaving it empty. What is the result of still having the heating soure (gas or electric)still active. Is there a risk of fire if left unattended after the water tank is empty, and if so, how long.
I want to install shut-off device at both of my places. Also travel alot and concerned about the fire danger.
Any and all help would be appreciated.

with an electric hot water heater, if it is trying to heat an empty tank no risk of fire but will burn the element out. but of course if the tank failed a burnt out element is the least of your worries.

Thanks for the advice on the electric tank. What about a gas one.
I have both.
