What is the relative toxicity level of hydrogen cyanide?

• A. Low
• B. Moderate
• C. High
• D. Very High

Answer: (C)

Hydrogen cyanide is classified as having a high toxicity level due to its ability to interfere with the body's use of oxygen at the cellular level. It is a potent chemical that can be lethal in relatively small doses, affecting the central nervous system and leading to severe health consequences, including death. The rapid onset of symptoms after exposure, such as dizziness, confusion, and respiratory failure, further emphasizes its high toxicity. This makes it extremely hazardous in both occupational settings and potential accident scenarios. Thus, understanding the toxicity of hydrogen cyanide is crucial for ensuring proper safety measures and response protocols in environments where it might be present.
