BAN ON FIRECRACKERS
- The Supreme Court said a preliminary enquiry by the CBI into the firecracker industry, including in Tamil Nadu, revealed rampant violation of its ban on use of toxic ingredients like barium and its salts.
- In March 2020, the court ordered the CBI Joint Director in Chennai to conduct a “detailed” probe into allegations of violation of the court ban in 2018.
- According to the report, a chemical analysis of the samples of finished and semi-finished firecrackers and raw materials taken from the manufacturers showed barium content.
- The case gained significance with the onset of the wedding season and festivals like Dussehra and Deepawali.
- Use of Aluminium powder, sulphur and potassium nitrate produces noise.
- Use of barium nitrate (green) and strontium nitrate (red) emit light. A combination of barium nitrate and strontium nitrate in varying proportions produces different colours.
- Aluminium powder is used in sparklers.
|Antimony||Antimony sulphides are used in the production of the heads of safety matches, military ammunition, explosives and fireworks.
Risks: Inhalation of antimony trioxide is suspected of causing cancer.
|Mercury||A mercury compound called "Mercury(II) fulminate" is a primary explosive.
It is mainly used as a trigger for other explosives in percussion caps and blasting caps.
|Arsenic||Arsenic is generally non-combustible.
But Arsine, a compound of arsenic is highly explosive and toxic gas. It is used as an agent in chemical warfare.
|Lead||Lead azide and lead styphnate, compounds of lead are found in most heavy grade explosives.
Instead of red lead we have switched to bismuth oxide.
|Lithium||It is potentially explosive when exposed to air and especially to water.|
