Research of change of protective properties of fire fighter’s protective clothing at multicyclic operational action

The results of research of influence of the basic operational factors on the change of protective properties of fi re fighter’s protective clothing are presented. Mathematical models of dependence of stability to thermal action of the package of materials and the number of cycles of action are received by various factors of deterioration. The methodological approach for classification of factors of deterioration by degree of influence on reduction of protective properties of a package of materials of fi re fighter’s protective clothing is offered.
