Question : Fire extinguishers emit which gas?
Option 1: Carbon monoxide
Option 2: Chlorine
Option 3: Carbon dioxide
Option 4: Nitrogen
Correct Answer: Carbon dioxide
Solution : The correct option is Carbon dioxide .
For fire suppression, fire extinguishers release CO 2 gas. Carbon dioxide fire extinguishers emit CO 2 , a non-flammable gas that displaces oxygen to reduce the flames, as fire needs O 2 to keep burning. CO 2 can be used to extinguish Class B (flammable liquids and gases) and Class C (electrical) fires. Portable fire extinguishers are meant to manage or extinguish minor flames in emergency circumstances.
