In the Triple Rinsing Procedure, after the initial drain, the container is refilled with water to what fraction?

• A. 1/4-1/3
• B. 1/2
• C. 3/4
• D. Full

Answer: (A)

Rinse volume in triple rinsing is kept small but effective, so residues are removed through repeated cycles rather than one large rinse. After the initial drain, you refill the container with water to about one-quarter to one-third of its capacity. This amount provides enough liquid to loosen and carry residues when you agitate, while keeping rinse water manageable to handle and dispose of. You then repeat the rinse two more times, each time refilling to the same fraction. Using larger amounts, like half, three-quarters, or filling to full, wastes water and can make disposal harder, while a smaller amount wouldn’t adequately rinse residues over multiple cycles.
