Question

Which chemical is used in fire extinguishers? How is it harmful

Answer 1

dry co2 is used in fire extinguisher

Answer 2

Sodium bicarbonate, regular or ordinary used on class B and C fires, was the first of the dry chemical agents developed. In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That is, the gas drives oxygen away from the fire, thus stopping the chemical reaction.
