SC permits green crackers in Delhi-NCR on Diwali; blanket ban kicks in from Nov 9

The Supreme Court created a brief exception for green firecrackers in Delhi-NCR. People may use them only on November 7 and 8, during specified morning and evening hours. This matters because the court is balancing festival celebrations with concerns about air pollution.

The court also excluded firecrackers containing Barium and any products not approved by CSIR-NEERI as green crackers. The permission is therefore limited both by time and by the type of firecracker used. It does not allow unrestricted bursting across the region.

The complete ban starts on November 9. The court also imposed 300-metre no-firecracker areas around listed sensitive locations. The order was issued while hearing petitions covering air pollution, firecrackers, stubble burning and solid waste management in the National Capital Region.

The Supreme Court set two daily windows for green-firecracker use in Delhi-NCR on November 7 and 8. The first runs from 6 am to 7 am. The second runs from 8 pm to 10 pm. These limits sharply narrow when celebrations may take place.

For example, someone wanting to burst an approved green cracker must wait until the relevant window opens. Bursting it at 7:30 am or 10:30 pm would fall outside the hours permitted by the order. The rule works by controlling both the dates and the clock.

This temporary allowance ends when the complete ban begins on November 9. The court also prohibited firecrackers near hospitals, schools and other protected sites. Those restrictions apply alongside the time windows, so an approved product is not automatically allowed everywhere.

In this article, green crackers are the firecrackers approved by CSIR-NEERI. The court permits only this approved category during the limited November 7 and 8 windows. This distinction matters because the order is not a general permission to use every kind of firecracker.

The key mechanism is certification. A product must be recognised as a green cracker by CSIR-NEERI, while firecrackers containing Barium are specifically excluded. Products that lack the required approval are also not permitted. The article does not list the technical tests or ingredients used to classify them.

In broader established usage, green crackers are intended to reduce pollution compared with conventional fireworks, but the source does not explain their performance or standards. The practical reality is clear: approval is required, and the complete ban still begins on November 9.

The Supreme Court ordered no firecrackers within 300 metres of hospitals, nursing homes, primary and district health centres, old-age homes and notified silence zones. Educational institutions are also to be included. These places will be marked and publicised as No-Cracker Zones.

For example, a celebration near a hospital cannot simply rely on an approved green cracker or an allowed time window. The 300-metre restriction still applies. The order uses location-based protection, keeping fireworks away from places associated with healthcare, older people, education and designated quiet areas.

The article does not give separate medical or noise explanations for every category. It identifies these locations as protected areas and requires clear public marking. This should help residents know where the restriction applies, while enforcement will determine how effectively the zones are followed.

A 300-metre radius means every point within 300 metres of a protected location is covered. If treated as a circle, the area is about 282,700 square metres, or 0.28 square kilometres. The exact shape on the ground may vary because the restriction is measured outward from each listed site.

For example, a home, street or celebration spot inside that distance from a hospital falls within the restriction. People may not burst firecrackers there, even if the product is an approved green cracker and the clock is within the November 7 or 8 windows. The location rule works alongside the time rule.

People living nearby are not told to leave their homes by this order. They must avoid bursting firecrackers within the protected radius. The court also requires these areas to be marked and publicised, helping residents identify the boundary before celebrating.

When many firecrackers are burst together, the air can become heavily polluted for a period. Fireworks release smoke, gases and particles from combustion. Fine particulate matter can remain suspended in the air and reduce air quality, especially when weather conditions limit dispersion. The article gives air pollution as a central concern.

The public-health mechanism is exposure. People nearby breathe the polluted air, and those with asthma or heart and lung conditions may be especially vulnerable. Noise can also disturb people and animals, although the source focuses on air pollution and court restrictions rather than listing detailed health outcomes.

The article does not provide pollution readings, hospital figures or a measured health impact. Its response is preventive: restrict the dates and hours, exclude Barium-containing and unapproved crackers, and create protected zones. The complete ban from November 9 represents the next, stricter step.

Particulate matter, or PM, is a mixture of tiny solid particles and liquid droplets suspended in air. The smallest particles can be inhaled deeply. Fireworks create particulate matter through burning fuel and oxidisers, and coloured effects can add metal-containing particles. The source does not define PM, so this explanation uses established scientific knowledge.

Fine particles can travel beyond the nose and upper airways into the lungs. Some may pass into the bloodstream. The body can respond with inflammation and stress on blood vessels, which can worsen breathing problems and increase strain on the heart. Risk is higher for people with existing respiratory or cardiovascular illness.

The article does not provide particle measurements or specific medical case numbers. Its restrictions address the exposure source by limiting firecracker types, hours and locations. The complete ban from November 9 is the strongest measure described for reducing this pollution.
