This decision prioritizes public health and safety, which must be the paramount concern when faced with identified health risks. Mohammed Al-Farsi, as an external inspector, has professional credentials and has identified a specific hazard (mold spores) that poses documented risks, particularly to immunocompromised individuals like Dr. Carter. While Dr. Carter's expertise in archaeology is valuable, her respiratory illness may actually cloud her judgment about airborne hazards, and her suspicion about motives doesn't negate the physical evidence of contamination. Quarantining allows for proper testing while protecting visitors and staff, demonstrates institutional responsibility, and can be communicated transparently to avoid worse reputational damage than a temporary closure would cause.
