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

Answer

Brief Explanations:

CO₂ in fire - extinguishers is in liquid or solid (dry - ice) form under pressure. When released, it rapidly expands and cools to extremely low temperatures, which can cause severe cold - burns to human skin. CO₂ is non - toxic in normal concentrations, not corrosive, and while it can displace oxygen and cause asphyxiation in an enclosed space, the main immediate danger to a person from a CO₂ extinguisher is the freezing cold.

Answer:

a) CO₂ is freezing cold
