Which margin symbol indicates independent cleanliness inspectors?

The margin symbol that indicates independent cleanliness inspectors is "CI." This designation specifically refers to individuals or teams responsible for assessing cleanliness without any influence or bias from those directly involved in the cleaning or maintenance processes.

Independent cleanliness inspectors play a crucial role in ensuring that standards are upheld objectively. Their findings are vital for maintaining the integrity of hygiene protocols, particularly in settings where cleanliness is essential for compliance with health and safety regulations. This autonomy allows for unbiased evaluations, fostering trust in the cleanliness assessments within the organization.

The other symbols do not represent this specific role or function and may refer to other categories or types of inspectors or processes that are not independent. Therefore, "CI" is the appropriate choice for identifying independent cleanliness inspectors.
