Does Your Process Require a Class A Oven?
January 2021
MARIETTA, GA ~
If you process a flammable product or remove combustible vapors from a product in an oven, you will need a Class A oven that meets NFPA 86 requirements. Flammable volatiles that pose a potential explosion or fire hazard can originate from paints, powders, inks, and adhesives. Potential threats may also originate from finishing processes, such as dipped, coated, sprayed, and impregnated materials as well as from polymerization or other molecular rearrangements. Combustible materials include substrate material, wood, paper, plastic pallets, spacers and packaging materials.
The NFPA 86 Standard for Ovens and Furnaces
As there is a wide range of industrial ovens to cover all possible application requirements out there, the NFPA 86 standard has grown to take everything into account, from the suitability of the materials that are used to comprise an oven, to the safety and precautionary interlocks that will serve as fail-safes in case things go wrong. Depending on the oven type, there’s a dedicated section of the standard that covers the full spectrum of its specialized functionality, and its specific role.
