The contributors ended up furnished a diagram with the space and images from the contents, partitions and ceiling. An approximate 2-square foot (0.19 m2) grid was founded along with the contributors have been questioned to select the grid Room that most represented their space of origin. Up coming, the members were offered with depth of char measurements for all written content products and depth of calcination measurements for most of the partitions for the same compartment fire and were being requested to re-study here the pictures and select a place of origin yet again.
