Question

Why is carbon dioxide preferred in fire extinguishers to put out fire in multi-storey hospitals?

Answer 1

Carbon dioxide in fire extinguishers:

• The reason for carbon dioxide being used in fire extinguishers is because of its capability of replacing oxygen from the fire.
• When the supply of oxygen is cut, fire extinguishes because fire grows in the presence of oxygen.
• The carbon dioxide is cool gas, hence can help in putting out the fire.
• Moreover, in a multi-storey building there must be electric appliances or electronic devices present.
• Carbon dioxide is a bad conductor of electricity and can prevent currents and shocks as well. Hence, safe to use.
