What does the Margin Symbol "CI" indicate?

The Margin Symbol "CI" stands for "Critical Inspection," which designates steps that require independent cleanliness inspectors, known as SCI (Site Cleanliness Inspectors) or RCI (Residual Cleanliness Inspectors). This symbol highlights processes that need a heightened level of scrutiny to ensure that cleanliness standards are strictly adhered to.

Using this symbol is crucial for maintaining quality control, especially in industries where cleanliness is essential, such as pharmaceuticals or food production. By requiring independent inspectors, the process aims to eliminate biases and ensure that cleanliness protocols are followed rigorously. This oversight is particularly important to prevent contamination or defects that could arise from inadequate inspections.

In contrast, steps that require critical inspection or immediate review do not necessarily involve the specific oversight from cleanliness inspectors, and actions that can be performed without supervision do not meet the rigorous standards implied by the "CI" symbol. Thus, the correct interpretation of "CI" effectively underscores the necessity of independent inspection in maintaining quality assurance.
