The main corridor gives access to the lift as well. Figure 2: Typical Floor Plan (1-4)Fire Risk AssessmentThe apartment block contains a ground floor and four (4) upper floors, with three self- contained flat units on each floor, totaling to 15 flat units across the building. Each of the flats on the upper floors can be accessed indirectly off a single stairway and a single lift servicing a common corridor. The structure is of substantial construction, comprising of concrete floors, 150mm thick, with external masonry walls, 200mm thick. Partitioning walls are 150mm thick. This s tructure provides a good standard of fire resistance between adjacent flats, between flats and common parts and between different floors. The lack of any communal fire alarm system depicts the adoption of the ‘stay put’ policy, which is supported by the construction materials. All doors are made of hardwood, except those covering closets, which are thin panels of softwood. The lift doors are made of rigidized metal (steel) as well as the whole lift assembly. There are large, openable windows in all rooms with outside facing walls, to allow adequate venting of smoke. The staircase also has large openable windows on the outside facing wall. However, the main corridor and lobbies for each flat do not have any windows, which could present a hazard of smoke build- up should the fire reach these locations. The largest travel distance from the farthest point to the flat entrance was found to be. It is crucial to mention that this exceeds the maximum travel distance allowed in Approve d Document B â€" Diagram 3Figure 3: Flat with restricted travel distance from furthest point to entranceThe flat closest to the lift has the smallest internal entrance halls. The other flats have relatively long internal entrance halls, which could pose a hazard as occupants will be required to travel longer distances, in a fire outbreak, to reach areas of safety. The bedroom of the single flat is also located closer to the flat entrance door than the kitchen. For the other flats, occupants in the bedrooms may be exposed to fire as they try to exit the flat. The floor space for the larger flats was found to be and for the smaller flat, totaling to, excluding the common corridor. Using a floor space factor of â€" Table C1, the maximum total occupancy for each floor comes to approximately32 persons per floor. The total number of people who will use the ground floor stairs in the case of evacuation will be 160 persons. The widths of the individual flat lobbies, the common corridor an d the staircase are large enough to evacuate all the occupants in the case of an outbreak and also provide the firefighting service access to the blaze. â€" Table 6
