Analiza zasiegu widzialnosci w dymie powstalym w czasie spalania materialow poliestrowych
The changes in visibility range in smoke generated during thermal decomposition and combustion of polyester materials (PES) in the model room-corridor scheme during 1st stage of a fire development were analyzed. The effects of external heat flux density and flame-retardants on the course of changes of visibility range in smoke versus time were investigated. Critical time of visibility reduction was used as one of possible criteria of assessment of possibility of people evacuation. The MoO3 or Sb2O3 flame-retardants were used in an amount of 14 wt. %. The largest average value of specific extinction area of smoke was determined for PES containing 14 wt. % Sb2O3 and lower for PES containing 14 wt. % of MoO3 and unmodified one. The calculation of visibility range reduction in the model room-corridor scheme indicated the fastest visibility range reduction in smoke for the combustion of PES containing 14 wt. % of MoO3.
