I see there is some disagreement with the type of oven to Safely use for Power Coating.......
FWIW I worked in the automotive paint industry for a few years and I can tell you that ALL of the powder coat ovens I have been in have ALL been Natural GAS. The ovens are heated through a heat exchanger so there is No Open flame in contact with the power coat material. The Main Safety point to be Aware of is that Powder in just about ANY FORM (yes even normal cooking/baking flour) will become highly Flammable if not explosive WHEN it is ATOMIZED AND freely floating in a contained Oxygen Rich environment! The changes for a flash over are very high at that point and Any open flame OR SPARK from an electrical source could produce an explosive result.
