igned to have very high levels of reliability. 3.3.3 Height of Building It takes longer for a tall building tobe evacuated than a short building and therefore the structure ofa tall building may need to have a higher level of fire resistance. The implications of collapse of tall buildings on adjacent properties are also greater than for buildings of only several storeys. 3.3.4 Limited Extent of Burning If the likely extent of burning is small parison with the plan area of the building, then the fire cannot have a significant impact on the overall stability of the building structure. Examples of situations where this is the case are open-deck carparks and very large area building such as plexes where the fire-effected part is likely tobe small in relation to area of the building floor plan.
