However! Fire rated extraction booths may be your solution to increasing your solvent limits without expensive engineering, labor and materials. Control areas are built when the building area exceeds the maximum allowed quantities of solvent (MAQ). Your MAQs are defined by the building type and a couple characteristics such as fire suppression and solvent storage, for example. A control area is designed to multiply your maximum allowed solvents by separating a chosen area from the rest of the building with fire walls. This separation actually allows you to have multiple ares inside your building that reach the MAQ. A F-1 occupancy building (standard manufacturing building) can have (4) control areas on the first floor of the building, each with it's own separate maximum allowed quantities of solvent.Therefore, you could potentially have (4) areas with 480 gallons of ethanol, in a F1 occupancy building without having to build any additional fire walls. This is a huge advancement in the extraction booth tech and is patented by C1D1 Labs LLC!
