UL 1278 specifies safety shutoffs when required, so make sure you buy a
UL approved heater.

The Holmes heater mentioned early is claimed to have an "overheat
shut-off", - http://www.allergytech.com/holmes_heater_hch4166.htm

Some heaters have tip-over shutoffs, some have overheat shutoffs, and
some (like oil/water filled ones) may not need shutoffs (because they
don't get hot enough).
