This is a Safety Design Form for a NFPA Class A solvent atmosphere oven manufactured by The Grieve Corporation. The form documents the specifications and approved operating conditions for a convection heating oven located at McCconnell Air Force Base in Kansas (zip code 67221), owned and operated by the 22/931 MXS Composites Building.

The oven is designed specifically for curing aircraft composites, including carbon/graphite, fiberglass, Kevlar, and boron materials, with product batches weighing 10-500 pounds. The system uses gas-fueled convection heating and processes solvents including methyl ethyl ketone, acetone, alcohol, and methyl propyl ketone, with solvent and volatiles entering the oven at 0.20 gallons per batch. The oven operates at 500 degrees Fahrenheit with internal dimensions of 279" x 118" x 133" (2,534 cubic feet total volume), accommodates baking times of 1-8 hours per batch, and includes a thirty-minute purging interval between operations. Fresh air is admitted at 343 standard cubic feet per minute at 70 degrees Fahrenheit, while exhaust air is removed at 677 actual cubic feet per minute at 500 degrees Fahrenheit. Products of combustion do enter the oven during operation. The form explicitly warns against deviating from these specified conditions and notes that the information provided is for performance checking purposes only and does not constitute a guarantee of equipment performance.
