Portable heater for use in barn

[Brown cattle]

Anybody know of a safe portable heater for calving barn. Don't want to start a fire.

Is the heater for you or the calves?

I know 2 guys that burned down barns using them.  The one made the conscious decision to leave it running unattended over night with cattle loose in the barn.  He lost a barn, equipment, hay, and cattle.  I will assume this is not your intention.
