Only green crackers can be burst during a two-hour window – 8 pm to 10 pm – on Kali Puja and Diwali . Bursting any other type of cracker or using green crackers at any other time is illegal according to a 2021 state PCB order, later endorsed by Calcutta High Court. At Wednesday’s meeting, police told the fireworks traders to maintain a minimum gap of 9 ft between stalls. Organisers of Bazi Bazaars have to submit samples of the crackers to police by 11 am on Thursday.
“We hope to get the allotment letters soon,” said an organiser. A trader said they will submit two sets of samples to police as one set will be sent to NEERI. Bazi Bazaars are also held at Kalikapur and Behala.
Kolkata: Kolkata: QR codes will no longer determine whether the cracker you are buying is a legally approved green cracker or not, officials of National Environmental Engineering Research Institute (NEERI) told fireworks traders on Wednesday at a meeting attended by police and pollution control board (PCB) officials. Fireworks traders said the new applicants were not invited to the meeting with police on Wednesday, giving the indication that the old organisers will retain the right to hold the fairs. On Friday, Kolkata Police will conduct tests of the green crackers to be sold before Kali Puja and Diwali.
