Since kerosene heaters involve burning fuel creating flames, they can be somewhat dangerous if not handled properly. Guidelines like placing heaters on a flat, hard surface and making sure they are not too close to flammable objects or materials should always be heeded. Most kerosene heaters also have a number of built-in safety feature to make using them less dangerous. Features to look for include one-touch shutoff, automatic safety shutoff, a tip-over switch that shuts the unit down if it is knocked over, and protective safety grills around heating units. Remember, safety is of utmost importance, so don't overlook these factors when making a selection.
