The exercise that was conducted on Wednesday revealed that single crackers were within the permissible noise limits, but the series of firecrackers violated them. The readings showed the series of firecrackers had a noise level of 140 decibels, while the prescribed level is 105 decibels.

According to Awaaz foundation, the MPCB officials have stated that they will recommend to the Controller of Explosives that these be banned.

“A total of 25 firecrackers of different types, which were purchased from the open markets were tested. The highest noise level recorded for the single bombs (permissible limits of 125 dB) manufactured across the brands was 119dB and though it was below the permissible level it was higher than the maximum noise level recorded in 2016, which was 117dB,” shared Suraiya Artes from Awaaz Foundation.

According to Artes, the major worry this year could be the series firecrackers if not brought within the permissible noise levels as the highest noise level recorded for series bombs such as the 10000 Lar- manufactured by Win Fireworks violated the prescribed limit for series firecrackers. “While the noise levels prescribed is 105dB, the lar measured 140.5 dB, which is a major concern,” informed Artes.

Another concern raised by officials of MPCB was that in general, the smoke and dust pollution caused by all crackers seemed to be higher than last year. “The firecrackers will also be tested for their chemical composition to determine other pollutants,” said a MPCB official adding similar tests will also be carried out all over the State and a report will be shared with Controller of Explosives.

As per its standard procedure MPCB will measure noise levels during the Diwali period between October 19 and 22.
