Actual questions of fire safety of materials internal structural elements for special vehicles

Introduction. Special requirements for fire safety, in particular for interior decoration, must be formulated for vehicles that are associated with the transport of people and goods, the rapid evacuation of which can not be carried out in the event of a fire. The current regulatory documents do not contain fire safety requirements or do not fully reflect them, which does not ensure the safety of personnel and cargo in the event of a possible fire.

Problems of the issue. The fire hazard assessment of materials used in the internal structure of vehicle elements is limited to determining the speed of flame propagation on a horizontal surface from a low-power ignition source and does not take into account other fire hazards that affect the safe evacuation of people. The purpose of the work is to develop proposals for improving the fire safety requirements of interior materials of special vehicles.

Results and discussion. A comparative analysis of existing regulatory criteria and methods for assessing the fire hazard of materials used for the interior of vehicles. The results of experimental evaluation of fire hazard parameters of materials showed that they are classified as non-flammable according to GOST 25076, according to other standard methods can be considered flammable, capable of forming a burning melt and extremely dangerous in terms of toxicity of Gorenje products.

Conclusions. It is advisable to limit the use of flammable materials in the interior of special vehicles and, along with the method used for assessing the fire hazard, make mandatory requirements for the exclusion of the formation of a burning melt and the toxicity of combustion products.
