Carbon tetrachloride is most likely to cause damage to the:

1. Heart

2. Lungs

3. Liver

4. Bones

The correct answer is: Liver

Carbon tetrachloride is most likely to cause damage to the liver due to its metabolism and the toxic effects it produces when the body processes it. When inhaled or ingested, carbon tetrachloride is converted in the liver to reactive metabolites that can lead to cellular damage. This damage manifests as hepatotoxicity, resulting in issues like fatty liver degeneration, liver necrosis, and can eventually lead to liver failure if exposure is significant. Understanding the specific effects of toxic substances on various organs is crucial for safety professionals, as it helps in the development of prevention strategies and response protocols in situations involving hazardous materials. In contrast, while other organs such as the heart, lungs, and bones can also be affected by various chemicals, carbon tetrachloride's primary association is with liver damage due to its toxicological profile. This highlights the importance of recognizing the unique pathways and risks associated with specific chemicals in occupational health and safety.
