Question: Can a flammable cabinet be put on a riser to allow use of something below it?
Answer: I’m not aware of any specific prohibitions of this, but there are some things that you will want to consider. A flammable cabinet is designed with an air space at the bottom that serves as natural insulation. In the event of a fire, the temperature of the air in this space would increase before the temperature inside the cabinet. To retain that capability, you would only want to place the cabinet on a solid surface much like the floor that it would otherwise be on. That surface needs to be level so the cabinet remains square, a necessity for the doors to properly close and latch.
There is also a requirement that combustible materials not be stored near cabinets, so a riser could not be made of a material such as wood. Pre-fabricated steel frames are available for many standard-sized cabinets. They have a height of 4 inches with forklift pockets to allow movement of an empty cabinet with a forklift. This kind of frame is also used to elevate a cabinet to keep the bottom from rusting in an area that is moist or wet.
