Which of the following best describes the nature of flowables (F) during handling?

The best choice is one that accurately reflects the characteristics of flowable formulations during handling, and option B effectively describes flowables as leaving visible residue and being abrasive. Flowables are often thick, liquid products that can contain suspended particles, contributing to their tendency to leave residue after application. This residue is a critical consideration in the handling and application of these substances, particularly in maintaining equipment and ensuring effective cleaning.

Additionally, the abrasive nature of flowables can affect both application equipment and other surfaces they come into contact with. When dealing with flowables, it's important to note that their particle content can lead to wear on application machinery, necessitating careful handling practices. Therefore, understanding these properties is crucial for safe management and application within right-of-way maintenance or agricultural contexts.

The other options do not encapsulate the physical nature of flowables accurately, as they do not highlight these significant characteristics of visibility and abrasiveness associated with the handling of flowable products.
