Question

precisely! there are usually two different types of fire extinguishers: co₂ based extinguishers and foam based extinguishers. never use a co₂ based extinguisher on a person. do you know the reason why? a). co₂ is freezing cold b) the person would suffocate c) co₂ is toxic d) co₂ is corrosive

Explanation:

CO₂ extinguishers release highly cold gas as pressurized CO₂ expands rapidly on discharge, which can cause severe frostbite. While CO₂ can displace oxygen, the immediate critical hazard of direct use on a person is the extreme cold. CO₂ is not toxic in this context nor corrosive.

Answer:

a). CO₂ is freezing cold
