Design
Sheep dip is available as wettable powders, pastes, solutions or suspensions which are used to prepare diluted solutions or suspensions. The term is used both for the formulation itself, and the trough in which the sheep is dipped. The sheep are completely immersed in the preparation.
There are two broad classes of sheep dip: organophosphorus compounds, from which chemical warfare agents were later developed, and synthetic pyrethroids. Organophosphorous compounds are very toxic to humans, as they travel easily through the skin. When traveling over water, containers for these sheep dips are subject to United Nations regulations which state that they must remain legible after immersion in water.
Plunge sheep dips may be a permanent in-ground structure or a steel transportable mobile dip. Invented after the permanent plunge dip was the rotating, power spray dip. These dips are redundant in the major sheep breeding countries, as the backliners and jetting provide a better alternative.

Famous quotes containing the word design:
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
