What is a primary hazard associated with dry flowables (DF) or water-dispersible granules (WDG)?

The primary hazard associated with dry flowables (DF) or water-dispersible granules (WDG) is their high inhalation hazards. These formulations are composed of fine particles that can become airborne during handling, mixing, or application. Inhalation of these particles can lead to respiratory issues and other health problems, making proper safety precautions essential when working with these products.

While dry flowables can indeed be abrasive on equipment, this characteristic does not pose a direct health hazard in the same way that inhalation does. Moreover, these materials typically require thorough agitation to ensure they dissolve and disperse properly in water; hence, the choice that suggests they require no agitation is incorrect. Another misconception is that dry flowables leave no visible residue, which is not consistent as they can leave a visible deposit on application surfaces depending on the formulation and concentration.
