Summary

A zone model was used to evaluate fire hazards from burning plastics [polyurethane foam, foamed polystyrene (PSS), poly(vinyl chloride)] and natural materials (wood,cotton, flax). Fire hazard parameters are: temperature, rate of temperature rise, position of smoke zone. Fire was assumed to develop in a room 100 m2 in area and 400 m3 in volume equipped with two vents 12 m2 in total area. Maximum area of fire is reduced to 20 m2. Computer calculations revealed that the temperature of the smoke zone is higher with burning plastics than that with natural materials; higher is also the rate of temperature increase. The highest temperature of the fire zone occurs with PSS (993°C) and the lowest with cotton (195°C). The highest rate of temperature increase has been observed for PVC (5.84°C/s) and the lowest one for cotton (1.96°C/s). The highest fire hazards are provoked by foamed polystyrene and the lowest by cotton
