The state pollution control board has approved the use of all 26 types of firecrackers that were tested for noise levels on October 18 in Mumbai. However, the result for a chemical analysis test of the firecrackers is yet to be issued b the board.
Officials from the Maharashtra Pollution Control Board (MPCB) told HT on Thursday that individual noise levels from serial (1000 series) as well as single crackers, was calculated by their scientific officers and the decibel (dB) levels were found to be below the permissible limit of 125 dB .
“Apart from testing crackers in Mumbai, we have received reports of similar firecracker testing done across the state over the past week. Noise from none of the crackers surpassed safe limit under noise rules,” said VM Motghare, joint director, MPCB. “We submitted our findings to the Controller of Explosives, Nagpur with a conclusion that none of the crackers should be banned this year.”
On October 18, the annual testing by MPCB and anti-noise campaigner Awaaz Foundation, found the noise levels from serial crackers (1000 series) to be at a maximum of 116 – 118 dB (1000 series at 116.2dB). The testing was done in an open ground in Rashtriya Chemical and Fertiliser (RCF) colony, Chembur, 12 days before Diwali.
While permissible limits for single crackers is 125 decibels (dB), a series of crackers (ladi) have limits between 90 decibel (dB) and 110dB, depending on the number of crackers put together. “For serial crackers, noise from each individual cracker from the series was tested and a logarithmic analysis showed that individual crackers were below 110 dB limit,” said Motghare.
Meanwhile, the results for the chemical analysis of the crackers are yet to be received from the pollution board’s laboratory. “While some of the crackers showed release of thick smoke and could have traces of lead and zinc, it is yet to be confirmed from our lab,” said Motghare.
Anti-noise activists said that there was a drop in noise levels due to enforcement as well as awareness. “During 2012, firecracker testing by different groups clearly showed a 100% violation for all firecrackers. While awareness has resulted in a lesser use of firecrackers, over the years, the firecracker testing done by our NGO, the pollution board and several complaints to the Controller of Explosives and the police that led to better enforcement and the manufacture of less noisy crackers,” said Sumaira Abdulali, convener, Awaaz Foundation.
