The primary ethical responsibility is to ensure the health and safety of visitors and staff (the principle of non-maleficence). The presence of mold spores, confirmed by an inspector, constitutes a credible threat, particularly to the lead archaeologist who has a pre-existing respiratory condition. While the archaeologist disagrees, the precautionary principle dictates that potential health risks should be mitigated immediately, even before full scientific certainty is established. Quarantining the sarcophagus is a reversible action that neutralizes the immediate danger, creating a safe environment for further testing, which can then provide the definitive evidence needed to resolve the professional disagreement between the inspector and the archaeologist. This choice prioritizes human well-being over reputational or interpersonal concerns.
