sound-emitting fire crackers (firecrackers)

Sound-emitting fire crackers are pyrotechnic devices whose primary effect is a loud explosive bang, as distinct from purely visual fireworks. They are regulated under the Noise Pollution (Regulation and Control) Rules, 2000, reinforced by Supreme Court directions, because of their sharp, high-peak noise and its impact on health, the elderly, the unwell and animals.

The controls are specific. The noise level of an individual cracker is capped (the standard limit is 125 dB(AI) or 145 dB(C) peak measured at 4 metres from the bursting point; crackers exceeding this may not be manufactured or sold). Bursting is restricted to limited hours — courts have confined permitted bursting to a defined window in the evening on festival days and prohibited it late at night (generally barring the 10 p.m. to 6 a.m. period). And in silence zones, around hospitals, schools and courts, sound-emitting crackers are prohibited entirely.

For most industrial operators this term appears in the Noise Rules schedule rather than in daily operations, but it can matter at the boundary: a plant near a residential or silence zone shares the same noise framework, and community cracker use is part of the ambient noise environment that surveys may capture. The relevance is mainly to understand the full scope of the Noise Rules the plant operates under.

For an Indian entrepreneur the guidance is contextual rather than operational: be aware that the Noise Rules covering your plant also regulate fire crackers, that the same silence-zone and night-hour logic applies, and that any on-site celebratory use of crackers must respect the noise cap, the permitted hours and any silence-zone prohibition. In practice this is a minor compliance point compared with DG-set and machinery noise, but it is part of the same regulatory fabric.
