Which of the following is NOT considered a hazardous substance?

The identification of substances that are hazardous is crucial in pollution response and environmental safety. A material that is classified as non-hazardous in federal regulations is specifically designated to not pose a significant risk to human health or the environment under normal conditions. This classification means that such materials do not require the stringent handling or disposal protocols applied to hazardous substances.

In contrast, the other options refer to substances that may pose risks or complications. For example, substances without safe disposal methods can lead to environmental contamination. Similarly, chemicals found in agricultural products may be hazardous due to their toxicity, even though they serve essential functions in food production. Common household products can also be hazardous depending on their contents and usage, for instance, products containing toxic chemicals.

Understanding the regulatory framework surrounding hazardous and non-hazardous materials is crucial for ensuring safety and compliance in pollution response activities. This highlights why the choice classified as non-hazardous is the correct answer to the question.
