Which material is unlikely to be classified as HAZMAT?

Sand is unlikely to be classified as HAZMAT because it is a natural material composed primarily of silicate minerals and does not possess the hazardous characteristics associated with substances that can pose a risk to health or the environment.

In contrast, oil, pesticides, and lacquer thinner are considered hazardous materials due to their toxic, flammable, or environmentally harmful properties. Oils may contain harmful additives or pose risks when spilled. Pesticides carry risks to human health and wildlife due to their chemical compositions designed to kill pests. Lacquer thinner, often a mixture of solvents, can be hazardous due to flammability and potential health risks from inhalation or skin exposure. Thus, sand’s inert nature and lack of toxic properties set it apart from the other materials in this context.
