Fire Protection for Mezzanine Floor Structures

Once we have determined if a mezzanine floor needs fire protection (usually to 60 minutes fire resistance) we will undertake the necessary work to fire rate the steel structure.

This is normally in the form of a fire rated suspended ceiling (installed to the underside of mezzanine floors) where both ceiling tiles & gridwork have both met or exceeded their specific test specifications from the manufacturer.

The purpose of fire rating a mezzanine floor is to allow personnel enough time to evacuate the area safely in the event of a fire and to allow fire fighters enough time to safely access the structure in order to fight the fire and to bring it under control.

Elements that make up a traditional fire protection system to the underside of mezzanine flooring include :-

•Fire Rated Suspended Ceiling & supporting gridwork.
•Fire Rated Bulkhead detail / Upstand to exposed edges of mezzanine floor.
•Fire Rated Column Casings (Galvanised or White) to all structural steelwork.
•Fire Rated Cavity Barrier within ceiling void at approved centres.
