Thanks Amiga 500
A little bit more on the rationale for my opening post.
Who checks that the filters are replaced with correct ones at the recommended time or sooner if contaminated?
Are these records available in real time to all airport health and safety experts that each aircraft makes a stop at (ideally before the aircraft lands)?
Are there random or regular checks (using e.g. hand held devices, that do not require maintenance operations) on filters and air ducts that are made or can be made, by airport health and safety experts, that aren’t the same checks that are carried out by the airline’s maintenence staff at routine schedules?
Why are these and other related questions possibly relevant?
Large numbers of pax are moved for long, medium or short haul periods all enclosed in a presurised cabin (a sealed container).
Aircraft are turned around very quickly for very obvious economic reasons.
Very few of these pax have had any form of adequate medical or health screening before boarding each flight. (dare I say it, some have even forged or obtained for a fee medical vaccination certificates required for entry to the UK)
Bacteria thrive in warm to warmer while viruses can thrive in both warm, warmer, cold and colder environments.
It is not just pax airlines that are affected by this but freighters as well.
There is much recent ado about containers (shipping and air) that are having to be checked very carefully on opening as they bring inside/outside them bacteria, viruses and all manner of small vermin.
Business premises (ie office blocks), hospitals, nursing/care homes, public transport are all potential harbours for bacteria and viruses to thrive in.
Why do these issues become more relevant – prevention is better than cure certainly in the UK, otherwise the NHS bears the burden. UK citizens lose time at work, school, college and university if they develop infections.
