What is a fire extinguisher?

Answer 1

• Fire extinguishers are a device in which carbon dioxide is produced in different forms for use as the extinguishing agent. It is a modem type of fire extinguisher in which liquid carbon dioxide is stored in a steel cylinder under pressure.
• Fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations.
• It consists of a metal container filled with water, Sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, or Sodium bicarbonate $\left({\mathrm{NaHCO}}_3\right)$ to produce${\mathrm{CO}}_2$.
• We generally use a soda-acid fire extinguisher or a CO₂ fire extinguisher which cuts off the supply of oxygen to extinguish the fire as they are prepared in water, which conducts electricity and there can be short-circuiting, causing another fire.
