Samples of Sound Producing Fireworks :

With a view to ensure strict compliance of statutory provisions regarding limiting decibel level of all sound producing fireworks as stipulated and set vide additional conditions of licenses and in compliance of directions of Hon’ble Supreme Court regarding the same, samples of sound producing fireworks are drawn during pre-diwali season from licensed shop / store houses by the department for the purpose of verification of sound level by testing at Departmental Testing Station.

Some of the important guidelines issued by CCE in this regard are as follows :

  • Samples of only sound producing fireworks should be collected from licensed shops. Sample of non-sound producing items like Sparklers, Chakkars, Flower pot etc. need not be collected as the purpose is to test for verification of sound level.
  • No test fee is to be charged in respect of such samples collected from licensed shops, during pre-dewali season as it is for the purpose of cross-checking compliance of adherence to the sound limit, in the interest of public safety.
  • In no case samples should be forwarded through courier or postal/ parcel service.
