What caused the impact?
It was found that a several crackers that had been stocked up had caught fire leading to this huge explosion. There is a firecracker competition at the temple and each time tries to better the other. In order to better the other team, it is ensured that the sound of the firecrackers are louder.
The police say that they are questioning the contractors to find out if any of the members of the team had instructed them to increase the capacity of the firecrackers. In this context the contractor may have added potassium chlorate which is a banned chemical. Moreover the norms do not permit the use of this chemical in firecrackers in India.

The impact was so loud that it could be felt at a radius of 1.5 kilometres. The storage unit which caught fire led to the series of explosions which left over 100 dead.

The storage room was not guarded properly, the police have alleged.
The use of potassium chlorate was banned in the firecracker industry in the year 1990. This was banned as the experts had stated that the chemical is a highly sensitive one. It is extremely sensitive to temperature and friction and hence it was banned in 1990.
