Industry Standards

• The National Fire Protection Association’s Standard NFPA 86 documents guidelines for the safe operation of industrial ovens and furnaces. All LEWCO Ovens are designed and manufactured to meet the requirements of this standard.
• Ovens and furnaces in which flammable volatiles or combustible materials are present in the work space are classified by NFPA 86 as Class A. Similarly, ovens and furnaces wherein no flammable volatiles or combustible materials are present are considered Class B. Due to the risk of fire or explosion, NFPA 86 requires specific safety equipment for all Class A ovens and furnaces. Fuel gas fired ovens and furnaces also require the same safety equipment. Specifically:
• Powered exhaust of capacity determined by burner size and solvent load present.
• Explosion relief of adequate area determined by oven or furnace volume.
