MPCB will monitor noise levels at 45 locations in Mumbai during Diwali

The Maharashtra Pollution Control Board (MPCB) tested 25 popular firecracker types at the RCF grounds in Chembur on Thursday, October 16. The exercise aimed to check which firecrackers meet the Central Pollution Control Board's (CPCB) Diwali sound limits. Police confirmed that all 25 types stayed within the allowed decibel levels.

The annual test is conducted in partnership with the Mumbai-based NGO Awaaz Foundation before Diwali. It serves as a benchmark to monitor ambient noise levels during the festival. Despite MPCB’s findings, the Awaaz Foundation raised concerns about the test conditions. They noted that the RCF ground has grass and mud surfaces, whereas firecrackers are usually set off on hard surfaces in residential areas, which amplifies sound.

However, it should be noted that the majority of the 25 well-known firecracker brands that were tested lacked QR codes and decibel ratings. Such firecrackers are prohibited by law from being sold or used, and the police should seize them. Certain brands, including Blueberry, King, Football-Double Dhamaka, 3D Sound Racket, Angry Bird, Indian King, Colour Sparklers, and Colour Sound, did not display decibel levels. 

The NGO also pointed out that during tests, firecrackers are ignited one at a time. In real celebrations, multiple firecrackers are set off together.

The 45-minute test included both traditional and eco-friendly firecrackers purchased by the Awaaz Foundation. MPCB officials measured sound levels with noise metres placed four metres from each firecracker. CPCB regulations allow sound levels up to 120 dB(A) for humans and up to 145 dB(C) to gauge effects on animals and birds. Officials said years of advocacy with manufacturers have paid off, as all samples now meet required standards.

Mumbai and Navi Mumbai are treated as separate zones. Similar tests are conducted annually across Maharashtra’s 12 zones. Awareness campaigns are held throughout the year based on these tests. The MPCB’s Explosives Department takes action against manufacturers who breach noise norms. 

During Diwali, MPCB will monitor noise levels at 45 locations in Mumbai, including quiet zones, residential areas, sensitive regions, and crowded markets.

Meanwhile, across Maharashtra, 158 sites will be observed this season.
