Which of the following is considered a hazardous material?

Household bleach is considered a hazardous material because it contains sodium hypochlorite, a chemical that can cause irritation or chemical burns upon contact with skin or eyes. Inhalation of bleach vapors can lead to respiratory issues and can be particularly dangerous in enclosed spaces. It is essential to handle household bleach with caution and follow safety guidelines during use, as improper handling can pose health risks.

In contrast, salt, water, and sand are generally considered non-hazardous materials under normal circumstances. They do not possess the same level of toxicity or risk that would classify them as hazardous. Salt is primarily used for culinary purposes and has well-known safe handling practices, water is vital for life and poses minimal risks unless in extreme conditions, and sand typically poses no health risks when used in construction or recreation.
