This project presents the work on assessment of flammability and explosion potential of waste from industries. Nowadays, revolution in lifestyle leads to the industrial revolution that at last gives some problems of industrial waste which may be toxic, ignitable, corrosive or reactive. If improperly managed, this waste can pose dangerous health and environmental consequences. The objective of this work is to investigate the flammability and explosion potential from a waste generated from industries by understanding the problem, selecting some mitigation methodology and preparing the safety analysis. This report will give some information regarding the hazards of the waste from industries focusing more on fire and explosion hazards. Two different liquid waste samples are collected from Kua!iti Alam Waste Management Centre, Seremban, Negeri Sembilan. The samples have been analyzed using gas chromatography (GC) to measure the compositions of all combustible species contain in them. The compositions have been identified for both samples. Gas Chromatography analysis also shows that both of the liquid waste samples majority are alkane group. It has been found from the GC results, that the both samples contain water. Therefore, the water extracted from the sample l and sample 2 using distillation experiments. Some properties related to flammability study have been measured. The density and heat of combustion of the waste samples have been calculated also using pyconometer and bomb calorimeter respectively. The results show that the density of sample 1 is 0.8023 g/ml and sample 2 is 0. 77 g/ml while the heat of combustion for sample l is 26320 J/g and sample 2 is 38354 Jig. The results of the experimental work were used for consequences analysis to calculate equivalent of TNT mass, overpressure, impact of overpressure, pool fire and boiling expanding vapor cloud explosion (BLEVE).
