These chemicals come from sources like aerosol sprays, refrigerants, solvents, and fire extinguishers, which release them into the atmosphere when used or disposed of.

What is the difference between dry chemical and hcfc 123 fire extinguisher?
Dry chemical fire extinguishers use a powder substance, such as sodium bicarbonate or monoammonium phosphate, to smother the fire and interrupt the chemical reaction. HCFC 123 fire extinguishers contain a clean agent called HFC-123, which is a halocarbon compound that extinguishes fires by removing heat and interrupting the chemical reaction. The main difference is in the extinguishing agent used, with dry chemical extinguishers being more versatile but leaving residue, while HCFC 123 extinguishers are cleaner and more suitable for sensitive equipment.
How do fire extinguishers affect the ozone layer?
No, fire works donot harm ozone layer.The substances that are causing ozone layer depletion are freons, CFC's etc.. These are called as ozone-depleting substances (ODS).
