A resident on the top floor (34th floor) of Heng Tai House, Fu Heng Estate, Tai Po has been diagnosed with the novel coronavirus COVID19 today (14-3-2020) RTHK reports [link] and he lives two floors above a couple already diagnosed on 11 March 2020 (same flat number ending with 13).
This is eerily similar to the incident in Tsing Yi in Feb. 2020, where I predicted drainage vent pipes issues, the pipe was subsequently discovered to be damaged, and additionally, repairs were carried out in nine (9) flats while those residents were evacuated.
This time, residents in Heng Tai House living in flat numbers ending with 13 and 14 , and living six floors below the “latest case” on 34th floor (top floor) will be evacuated RTHK reports [link].
Why this evacuation is limited to only six floors seems strange, citing droplets from the roof vent (which one?) reentering the building as the reason. While it is not impossible, the airflow pressure and patterns created around buildings are very complex, it seems highly unlikely, that only flats 13 and 14 would be impacted in this style of public housing.
It is worthwhile remembering that in the workplace, employers are responsible, by law, for the Health and Safety of their employees! Therefore workers in high traffic areas, for example, healthcare, building management, sewerage plants, transportation, etc. are responsible for their employees Health and Safety (H&S).
