Notes:
This paper examines the influence of oxygen and environmental temperature on the generation of smoke from burning polystyrene sheet. The experimentation was performed using a Stanton Redcroft HFTA linked to a Stanton Redcroft FTB Smoke Box. The results showed that different forms of smoke were formed depending upon the environmental conditions. For example, in oxygen-enriched atmospheres and at elevated environmental temperatures, as in spacecraft fires, large smoke particles were formed with a lower level of obscuration. This phenomenon was accompanied by higher rates of burn and high fire temperatures. At lower oxygen contents, as in real-life fire conditions, close to the Critical Oxygen Index, finer smoke particles were formed which gave a higher level of obscuration. The time to maximum obscuration was comparatively long.
