What are the two types of blood agents?

Cyanogen chloride (CK) and hydrogen cyanide (AC) are both classified as blood agents due to their mechanism of action in the human body. Blood agents work by being absorbed into the bloodstream and interfering with the body’s ability to use oxygen at the cellular level. This results in cellular asphyxiation, which can lead to loss of consciousness and death if exposure is significant and timely medical intervention is not provided. Cyanogen chloride, in particular, is a colorless gas that can cause severe respiratory distress, while hydrogen cyanide is also a colorless gas (or liquid at low temperatures) that is even more lethal in lower concentrations. Both agents highlight the critical nature of understanding chemical warfare and the necessity for preparedness and protective measures in military operations.

In contrast, the other choices represent different categories of chemical agents not classified as blood agents. Nerve gases affect the nervous system, whereas phosgene is a choking agent and mustard gas and lewisite are classified as blister agents. Understanding the distinctions among these various types of chemical agents is essential for recognizing their effects and required responses in a military context.
