(As we all know, fire regulations are the biggest killer of interior designers, especially in the field of tooling. For an interior decoration project, no matter how much the owner likes the design scheme in the early stage and how superb the construction technology in the later stage, if it wants to be put into use, it must pass the fire protection level. In practical work, most designers only pay attention to the design effect, and it is easy to ignore the rigid rules and regulations of some industries, which often leads to touching the red line of the fire prevention code without paying attention in the design process, which makes the previously finalized plan beyond recognition, or even completely overturn and redo, increasing additional workload and even losing old money. If you know some basic knowledge of fire laws and regulations, you can completely avoid these unnecessary troubles.)
