(Fig 1.6) The fire-resistance capacity of the compartmentalized wall and/or floor depends upon: ■ ■ ■ ■ ■ ■ Integrity, i.e. the ability to resist the passage of flames/hot gases and.or Insulation, i.e. the ability to restrict the temperature rise on the unexposed face Stability: the ability to withstand under the hose stream test when subjected to impact, erosion and cooling effects. COMPARTMENTATION Large buildings are typically segmented into smaller compartments with fire-resistive boundaries and protected openings through these boundaries. The objective of compartmentation is to confine a fire to a limited area for a specified time and thus slow down fire spread through a building, to leave more time for safe evacuation of the occupants, and to reduce property and indirect losses.T his advantage not only helps the occupants to evacuate from the building, but it also allows significant advantage to the fire-fighters to fight the fire in a relatively safer scenario. 25
