Is a vapor classified as a particulate?

Vapor is classified as a gas that is produced when a substance transitions from a liquid or solid state into a gaseous state. It consists of molecules that are in a gaseous form but are usually derived from a liquid or solid. Particulates, on the other hand, are tiny solid or liquid particles that are suspended in the air, such as dust, pollen, or smoke. Since vapors do not consist of discrete particles but rather molecules in a gaseous state, they do not meet the definition of particulates. Therefore, the classification of vapor as non-particulate is accurate and aligns with how these terms are used in environmental and workplace safety contexts.
