There is a misconception around OFSTED's requirement for displays in school so a joint circular has been produced to dispel them.  It can be viewed through the buildings section of BSO under the Fire Safety.

All schools must read and follow the guidance as displays such as those shown in the document not only endanger the lives of occupants in the event of a fire, but they are particularly hazardous for officers attending a fire who may have to enter the building in smokey conditions.   Not only do they hinder officers but officers can get tangled in them due to low visibility and unfamiliarity of the space.  

Please follow the guidance here
