Understand all associated hazard knowledge
A cellular room arrangement is the division of an area of a building into separate rooms, which are normally served by common corridors. Older office buildings and educational facilities are examples of this kind of structure. Buildings can contain both open plan and cellular sections.
The presence of dividing walls and rooms with more than one entrance can increase the complexity of fire and rescue operations and travel distances may be taller than expected due to the building’s internal layout.
It may be difficult to differentiate between walls that are load-bearing or fire-resisting and those which only divide space between different rooms. However, the dividing walls may help to contain a fire to a smaller area. Walls constructed using glazing systems may affect the use of thermal imaging.
Partition walls may not continue above a false ceiling to the floor above, which may allow undetected firespread in ceiling cavities between rooms.
