The heat transfer from the source of initiation to the adjacent surfaces is a physical phenomenon worth considering in the process of analyzing the fire. This complex phenomenon describes how the transport, exchange, and redistribution of the thermal energy are carried out and is based on the theoretical knowledge that describes the initiation and fire evolution in time. Flames transfer heat from nearby surfaces through two physical processes, convection, and radiation. A third mode of heat transfer is conduction,...

Under the effect of strong heat, chemical fertilizers tend to decompose. These decompositions can be followed by burns or explosions. The tendency to suffer self-sustaining decomposition is determined by the test method described in Test S.1 of the United Nation Manual of Tests and Criteria for the classification of ammonium nitrate fertilizers. The purpose of this work is to present the tests, experiments and interpretation of the experimental data necessary for the classification of chemical fertilizers based on...

The hydraulic systems used in the aviation industry use pressurized fluids that transmit energy to various driving systems of the aircraft (hydraulic motors, cylinders or hydraulic actuators). It is known that hydraulic fluids, along with the fuels used, present a potential risk of fire, which can lead to damages or the loss of the aircraft, often with very serious consequences. At the same time, in the event of a plane fire after the crash, hydraulic fluids can be an additional fuel source. For these reasons, the...
