Sladkaya [172]

Hi!


The answer would be C. Three

Explanation:

Floor dry compounds are absorbents that are employed in various settings to ensure complete clean up of waste, dust or spillages. They can be water-soluble or oil-emulsion based products. They are particulate like, and can be scattered over the spill, which they take up, and then cleaned. These can be used on wide-spread spills.

The hydrophobic mop has a front that absorbs materials lacking water, such as oil or hydrocarbons, and is effectively employed to deal with large spills.

A cleaning rag is employed for small spills, usually to cut down the cost of using new tissues and paper towels for spills. They are used frequently for bench-tops, and good quality rags can prevent scratches on surfaces.

Small spills are those which can be cleaned up with three or less rags, and larger spills are those which require more than three rags to clean up.
