Such ovens shall be constructed of metal and incombustible materials so designed as to preclude the direct application of flame to the materials in process. Ventilation shall be provided for each oven of sufficient capacity to maintain an oven vapor concentration at all times during the drying process of less than 1/4 the low explosive limit of the solvent used. All oven openings shall be maintained at a negative pressure relative to room pressure for inward flow. The controls for the safety exhaust and recirculating fans shall be properly interlocked with the gas supply line so that when the gas is flowing the fans are in operation. A time delay relay shall be installed to provide a minimum of four oven volume changes with fresh air and in the case of an indirect fired type of oven simultaneous purging of the combustion chamber before the ignition system can be energized and gas flow started. Each oven shall be equipped with gas burning equipment approved for such use and with electrical controls so arranged as to shut off the gas valve when ignition fails or the gas supply pressure drops to 2 inches of water. The use of a continuous gas pilot light is prohibited unless an automatic gas shut off valve is provided which will shut the gas off at the pilot light when the flame is extinguished or the supply of gas cut off. Electrical pilot ignition shall be of the continuous type or equal in performance, designed for use in high temperatures, with controls so inter-locked as to shut off the gas supply when current is interrupted. An auxiliary manually operated gas shut off valve shall be located not nearer than 25 feet from the oven so as to control the gas supply in the event of an emergency. Such ovens shall be adequately insulated on all sides and top to limit the maximum surface temperature to 140°F and to 160°F on the base, unless the floor is protected by a 3 inch mat of reinforced concrete placed over and bonded into the existing concrete floor and projecting not less than 6 inches outside the projected area of the equipment or unless an unenclosed clear air space not less than 4 inches above the concrete floor is maintained between the floor and the underside of the oven.

When equipped with duct ventilating system, the Infra-Red Ray Oven shall be adequately secured so as to prevent moving.
(B) Where the evaporation of a considerable amount of flammable vapors are involved, ventilated hoods located as near to the floor as practicable or enclosures shall be provided at the initial stage of the process with adequate exhaust system to discharge the primary evaporation from the solvents to the outer air, so that when the processed material progresses through the lamp drying tunnels only a comparatively small amount of solvent is left for evaporation. A space between such ventilating section and the drying section shall be maintained.
(C) Lamps and other electrical equipment shall be kept free from flammable deposits and adequate cleaning shall be maintained.
(D) Lamp and resistance heater type drying units shall be separated from spraying and dipping processes complying with these rules by a distance of at least 15 feet or shall be installed in a separate fireproof room.
