The purpose of the work is presenting principles of examinations for determining reducing the fire load density for coincidences other than expected in standard (in PN-B- 02852:2001). Examinations showed that in case of sawdust and pellets the burning was observed only an outer layer of stacks (of heaps) – up to 10 cmof the depth (rise of temperature above 220°C thatmeans above the ignition point). Flaming burning on the surface was moderately intense. Examinations showed that in case of tobacco no flaming burning was observed however the front of the high temperature moved deep into samples as a result of smouldering of the tobacco plant. The temperature rise higher than 250°C was observed on levels between 10 and 20 cm. Received results gives reasons for reducing densities of the fire load density for calculations: 10% for wood and tobacco; 20% for pellets.
