Explanation:

Rajasthan government had earlier banned the sale and use of firecrackers from October 1, 2021, to January 31, 2022, because of the danger posed to patients of Covid-19 and other diseases by their toxic fumes.

However, in the recent order, the state department amended the order by allowing the sale and use of only green crackers during Diwali, Chhath, Gurupurab, Christmas, and New Year.

Green Crackers

Developed by the Council for Scientific and Industrial Research (CSIR), green crackers emit pollutants at a 30% lesser rate than their conventional counterparts.

Green crackers are made using less polluting raw materials. Their chemical formulation ensures reduced particle emission into the atmosphere by suppressing the dust produced.

There are three types of green crackers available in India - SWAS, STAR and SAFAL.

SWAS stands for Safe Water Releaser

These crackers have unique property of releasing water vapour and /or air as dust suppressant and diluent for gaseous emissions and matching performance in sound with conventional crackers.

SWAS crackers eliminates usage of (KNO3) Potassium nitrate and Sulphurwith consequent reduction in particulate matter (30-35%) SO2 and NOx.

It has matching sound intensity with commercial crackers in the range of 105-110 dBA.
