T4 Sentinel tracking
DT
A few organisms are dangerous enough that finding them demands action, not just a note — the airborne mould Aspergillus fumigatus, a serious health risk to hospital patients and vulnerable people, is the prime example. T4 Sentinel tracking flags these highest-tier species, turning a routine clean into a health-protection measure where it is needed.
T4 Sentinel Tracking is the highest tier of the ATH Forensic Tier system (T1–T4), reserved for sentinel species whose presence demands mandatory action. The archetype is Aspergillus fumigatus — the T4 Sentinel, COSHH-applicable — whose airborne spores cause invasive pulmonary aspergillosis in immunocompromised patients (haematological malignancy, transplant recipients, advanced HIV). Tracking T4 organisms converts a routine clean into a health-protection and compliance obligation, particularly for hospitals and care settings, and links the biological registries directly to occupational and public-health duty.
