#Covid19 High risk (yellow) zone at temperatures 5-11°C (spring & autumn)

An urgent public health message about clean indoor air & #ventilation (not fines & roadblocks) can have immediate impact on virus spread & prevent cases Image
WHO: ‘we are very concerned about rise in cases in Europe as it heads into winter’

‘Colder weather leads to behaviours that favour transmission of a respiratory virus- people tend to crowd indoors to stay warm, more often in poorly ventilated spaces’ smh.com.au/politics/feder…
‘overwhelming evidence that *inhalation* represents a major transmission route’

‘we urge public health officials to add clear guidance about importance of moving activities outdoors, improving indoor air & improving protection for high-risk workers’ science.sciencemag.org/content/early/…
Germany’s top doctor: ‘Most people only pass it to one person.. But occasionally, someone spreads it widely, creating a cluster of infections that drives the pandemic’

**To avoid another lockdown Germany must focus on identifying & preventing clusters** bloomberg.com/news/features/…
#Level 5 has no plan to prevent super-spread clusters in ~known~ high-risk conditions (crowds, indoors,poor ventilation) such as happening in overcrowded homes & schools, nursing/care homes, meat/food plants, or risk mitigation in shops, offices, cars, buses/trains/planes) Image
‘After 9 months of epidemiological data, we know that this is an overdispersed pathogen, meaning that it *tends to spread in clusters* but this knowledge has not yet fully entered our way of thinking about the pandemic—or our preventive practices’ theatlantic.com/health/archive…
#Covid19 has meant hard choices & serious consequences, with an escalation in restrictions and enforcement.

But, if the rules aren’t being effective, could the rules be wrong? irishtimes.com/opinion/why-go…

[Thread] Clean air & Ireland’s inconsistent #Covid19 rules 1/

‘possibility of airborne transmission of SARS-CoV-2 through aerosols is still uncertain..no conclusive proof..further research needed’ HPSC, 22 Sept

^known very high risk & there’s evidence hpsc.ie/a-z/respirator…
..but ‘crowded indoor spaces have been shown to be associated with increased transmission.. determining what is due to proximity & poor hygiene practices, & what is ~due to poor ventilation~ though, is difficult’

^so, risk of spread due to poor ventilation is accepted by HPSC 2/ Image
..but, no rules from HSPC, just ‘suggestions, specifically for commercial & public buildings’ ..& only for mech ventilation, which is small % of all buildings ..but ‘residential & healthcare settings fall outside the scope of HPSC document’ ..& very limited advice for schools 3/ Image

Explainer: Why the changes to Irish fire regs for ‘open-plan flats’ put lives at risk

(could be a long thread, please bear with me, this is ~most critically important~ issue for discussions about our future housing, & it’s not getting any attention 1/
video is a recent rescue in Los Angeles, from 6th floor balcony of 25 storey building, in daylight, attended by 20 fire-trucks & rescue helicopter, in a fire-sprinklered & regulated building; 7 people & a baby injured, 10 homes burnt
(this is all important later in the thread) 2/
Typical 2-bedroom flat before reg changes;
note- balcony, hall separating kitchen from bedrooms, direct escape from bedrooms (not through kitchen), opening windows; + short main corridors with escape stairs every 6ish flats (kitchen, esp oil fire is a high-fire risk area) 3/

Building heights (again)..
here’s an example of how Planners consider building heights. First by looking at existing buildings 1/ (Liberties Dublin, Local Area Plan)
& taking account of broader issues... ‘high rise residential development is market driven & relies upon sufficient numbers of purchasers prepared to pay a premium’ 2/
& looking in great detail at the impact, both on the immediate area & on the city (looking in & looking out) 3/
