Question 228Safety & Environmental - QMED

The correct answer is D) freeze burns and blistering. Carbon dioxide (CO2) is a commonly used firefighting medium, but it can be dangerous under certain conditions. When discharged, the rapid expansion of CO2 can cause the temperature to drop significantly, resulting in freeze burns and blistering on exposed skin. This is because the rapid cooling can cause frostbite and damage to the skin and underlying tissues. The other answer choices are incorrect because they do not accurately describe the primary hazard associated with the use of CO2 as a firefighting agent. Hallucinations, carbon monoxide poisoning, and undulation are not directly related to the use of CO2 in firefighting.
