Which of the following is classified as a hazardous material (HAZMAT)?

The correct classification of Simple Green (a brand of cleaner) as a hazardous material (HAZMAT) stems from its potential chemical properties and effects on health and the environment. Although Simple Green is often marketed as a biodegradable and environmentally friendly cleaner, certain formulations may contain surfactants or other ingredients that can be classified as hazardous when spilled, improperly disposed of, or if they come into contact with skin or are inhaled in concentrated forms.

When assessing materials for hazardous classifications, considerations include the chemical composition, toxicity, flammability, and reactivity. In various contexts, professionals must identify and handle HAZMAT according to safety regulations and standards to protect people and the environment. In contrast, substances like water, oxygen, and sand are generally considered non-hazardous under typical conditions of use and handling, as they do not present significant risks to health or safety.
