Pune Police have banned sound-emitting firecrackers between 10pm and 6am except for light-only types, and prohibited the sale, use, and possession of 'atom bomb' crackers. Temporary vendor licenses are valid from October 20-24. Noise limits are capped at 125 decibels, and crackers are banned near silent zones, roads, and public places to ensure a safe, pollution-free Diwali.
