That kind of fire never entered my radar because of the reasons you
brought up.
The only fire I would worry about might occur from dust building up on
the heater, itself. After a long summer of woodworking and no heater
use, the dust that builds up on and in the heater from a lazy shopkeeper
who neglected to clean it out. Turn the heater on the first chilly day
to heat up the shop and the dust catches fire. I know I can smell it on
the top of my kerosene heater when I forget to blow the dust off. Maybe
it's just not hot enough to light it up.

Ah, gotcha.

In your position, I'd probably look at a small propane furnace,
properly vented. Like something you'd find in an RV.
