American Chemical Society (ACS) Laboratory Safety Practice Test

When a label states "Fatal if swallowed," it clearly indicates that the substance poses a significant health risk and can lead to death upon ingestion. This warning is a crucial part of chemical safety labeling because it alerts individuals to the extreme danger associated with the chemical. Understanding this label is essential for ensuring proper handling and storage of hazardous materials in a laboratory or workplace setting.

The phrase implies a need for immediate attention and caution, driving the point that precautions should be taken to avoid accidental ingestion. This helps to promote awareness and adherence to safety protocols, which are critical in managing the risks associated with toxic substances. In contrast, the notion that the chemical could be edible or a food product is misleading and risky, as is the suggestion that the chemical is free of health risks. Understanding the implications of such warnings is vital for anyone working with hazardous materials to ensure their own safety and the safety of others.
