Actually that's what I do. I just use a simple rotary timer switch on the heater plug and set it for 30 minutes or whatever. That way it will always switch itself off in case I forget. It won't exactly achieve ATEX rules, but it is a small thing that can help prevent an accident.
I also unplug my heating element when not in use. I don't consider just turning it off at the socket to be enough.
