I am building a small office in a warehouse that is rated Class 1 Division 2. I know I have to supply a slight positive pressure to the room to keep hazardous fumes out but I cannot find anything listing the requirements. Can anyone tell me how much positive pressure is required or does anyone know where I can find this information.
