Mezzanine Floor

Mezzanine Floor Fire Rating

Mezzanine floor installations do have legal requirements like fire protection to consider, this depends on a number of factors such as the use, size and extent of the mezzanine floor.

Basic Mezzanine Fire Rating Guidelines

If a mezzanine floor that is less than 10m x 10m in size, and occupies less than 50% of the area of the building in which it is located and this is not permanently occupied and is not regulary accessed for instance when being used for storage, then it will not need to be fire rated.

If a mezzanine floor that is less than 20m x 20m in size, and occupying less than 50% of the area of the building in which it is located and which is not permanently occupied and is not regulary accessed for instance when being used for storage, then it will not need to be fire rated provided it is fitted with an appropriate fire detection and alarm system.

If a mezzanine floor is going to be permanently used for functions like manufacturing or assembly, packing, office areas, canteen space or used as retail space where the general public will have access, then the floor will have to be fire protected irrespective of size.

Mezzanine floors that are larger than 10m x 10m and don’t have an appropriate fire detection and alarm system, all mezzanines larger than 20m x 20m and all mezzanines whose size exceeds 50% of the area within which they are located also need fire protection.

Fire rating is normally specified by building regulation control, we will discuss this with our approved inspectors and advise you if this is applicable for your mezzanine floor.
