Every one of the fire pattern research have been summarized in Additional file 1. This spreadsheet offers most of the test facts, basic instrumentation effects, list of indicators recognized or not and presents the probability for the identification of these indicators.
The higher layer gases are elevated in temperature and possess a chance to radiate warmth downward on to the tops of contents through the compartment. Fire investigators describe this consistent damage to tops of contents as radiant warmth problems remaining because of the upper layer.
