- Clear Overhead Clearance: For multi-shot repeaters and sky rockets, ensure at least 25 feet of vertical distance from balconies and trees.
Green Crackers FAQs
What makes a firecracker a "Green Cracker"?
Green crackers are formulated using eco-friendly formulations developed by CSIR-NEERI (Council of Scientific and Industrial Research - National Environmental Engineering Research Institute). They eliminate toxic barium nitrate and potassium nitrate, reducing particulate matter (PM2.5 and PM10) emissions by at least 30%.
How can I scan and verify the green cracker QR code?
Every genuine box manufactured in Sivakasi features a unique green logo with a QR code. Using the official CSIR-NEERI Green Cracker verification mobile app or any camera scanner, scanning the code confirms the manufacturer name, license number, and product formulation.
Are green crackers permitted in Bangalore, Chennai, and other metro cities?
Yes, Supreme Court and state pollution control board orders across Tamil Nadu, Karnataka, and Telangana explicitly permit the manufacturing, sale, and bursting of CSIR-NEERI certified green crackers during designated festive hours.
Do green crackers produce bright colors and sound?
Yes. Green crackers match traditional sparklers, flowerpots, and aerial repeaters in visual vibrancy and sparkle quality, while producing noticeably less pungent smoke and cleaner air dispersion.
