Why nitrogen preferred over carbon dioxide as propellant in DCP fire fighting system?

Answer 1

Carbon dioxide is a pollutant. Nitrogen is used by the plants. When you use carbon dioxide as a propellant,it adds more pollution or makes greenhouse effect worse....

Answer 2

Nitrogen is preferred over carbon dioxide as a propellant in DCP (dry chemical powder) fire fighting systems because nitrogen is an inert gas, which means it does not react with the chemicals in the dry powder. This ensures the stability and effectiveness of the fire extinguishing agent. In contrast, carbon dioxide can react with some dry chemical powders, potentially reducing the extinguishing efficiency of the system.
