The fireworks industry is a dangerous business. Many disasters occur due to manufacturing and use of fireworks. It has been recorded that there have been 15 disasters resulting from fireworks worldwide. Malaysia has experienced such tragedies through a fire and explosion of Bright Sparklers fireworks factory. This paper summarizes the sequence of events which led to the Bright Sparkler disaster and proposes some lessons which could be learned from the experience.

Major hazard organizations are dealing with hazardous material exceeding the threshold quantity. Major hazard organizations are relatively secure areas and cannot fail from single error. However, failure of an organization to control hazardous material usually results in a technological man‐made disaster. The conditions preceding the onset of technological man‐made disaster are collectively called the technological man‐made disaster precondition phase “incubation period”. A model has been developed representing the technological man‐made disaster pre‐condition phase where it focuses on the origin of the technological man‐made disaster. The model was based on detailed analysis of four technological man‐made disasters at major hazard installations in Malaysia.

Disasters are classified as natural and man‐made disasters. Man‐made disaster, which occurs at the major hazard installation, is a technological disaster. For an incident to be classified as technological disaster criteria are required to be met. Several criteria have been proposed by researchers and agencies defining the disasters in terms of casualties, economic loss and environmental impact. Few models have been drawn describing the sequence of development of the technological disaster. This paper reviews in detail the proposed criteria, which define the disaster. The paper also summarizes the models which describe the disaster stages. Finally the paper summarizes a proposed model of the technological disaster precondition phase for major accidents.
