- Abstract
- In the CEC project Guidelines for Management of Fires in Chemical Warehouses, TOXFIRE (EV5V-CT93-0275), carried out by a consortium of seven European partners, SP has carried out controlled large-scale combustions on amounts in the 100 kg range. This report describes experiments performed in the ISO 9705 room. Combustion experiments were successfully carried out under conditions from well ventilated to oxygen depleted on five organic materials with different chemical composition, containing the heteroelements nitrogen, sulfur and chlorine, respectively. The materials studied were polypropene, Nylon, chlorobenzene, chloro-nitro-benzoic acid and tetramethylthiuram monosulfide. A special instrument, a phi-meter, was build and used to measure the equivalence ratio, a measure of the degree of ventilation.
