‘The Approved Code of Practice (ACOP) to COSHH Regulation 7 states that if employers cannot prevent exposure to a biological agent, they should take steps to ensure that it is controlled adequately & consider all the requirements set out in regulation 7(3), (4), (6) and (7).’
/2
‘They [employers] should apply the principles of good practice and use each requirement where, and to the extent that:
• it is applicable;
• the assessment carried out under regulation 6 shows that it will lead to a reduction in risk.’
‘HSE guidance document HSG53 states ‘when in an airborne state, micro-organisms can be classed as particles, so can usually be removed by filter-type Respiratory Protective Equipment (RPE).’
‘You should always use equipment fitted with the highest efficiency filter possible (protection factor of at least 20) to control exposure down to the lowest levels.’
Therefore HSE recommends the use of an FFP3 for use against viruses.’
/5
‘Whilst FFP3 is the usual recommended control measure, it may not be reasonably practicable to use these if global supplies of FFP3 masks are low during a pandemic.
In this scenario, an FFP2 could be used as an alternative, as this is consistent with WHO guidance.’

IPC Cell guidance - unknown members, within @UKHSA
Droplet IPC precautions for SARS2 as it is not ‘wholly’ airborne, unless during an AGP, or in an AGP hotspot.

☣️ 1,600 🇬🇧 HCW deaths isn’t enough to change HMG-linked IPC Cell’s approach, who are *still* more interested in saving their own skin & covering up past errors.
☣️ #Omicron immune escape with greater transmissibility: ready for round 4 of Red Zone Russian roulette?
‘Healthcare leadership has lost its way. Its foundation should be in love, not lies. We are truly sorry for what we have done’
** ‘testimony’ 🙃
/🧵
‘We knew SARS2 transmission was airborne in Jan 2020, but instead of showing love to healthcare workers & being honest with them about the RPE shortages, we lied to them & kept on lying’
‘…we are truly sorry for what we have done’
/2
We knew AGP-only aerosol risk was a smokescreen - a thinly disguised rationing tool for RPE - but instead of being honest with HCWs, in love, we lied to them & kept on lying’
If you missed what Prof Sir Chris Whitty said on IPC & PPE, or just couldn't carry on watching after the amazing @Kevin_Fong [God bless you sir, & thank you for all you do 🙏]
TL/DR
/1
Sir Chris worked shifts on the wards in every wave
Wore FRSM mainly - as per IPC guidance, he said
HCID declassification had no bearing on IPC guidance
"I am not an expert on IPC'
/2
On national IPC guidance:
'quite a lot of people had partial responsibility'
Now we've seen IPC Cell minutes from 22/12/2020 & the plea from 'CB' for wider FFP3 use because:
'Our understanding of aerosol transmission has changed'
🚨Would you like to know whether very late 2020 was when *all* 🇬🇧Gov departments knew of the importance of aerosol risk?

'You should ensure that steps are taken to avoid people needing to unduly raise their voices to each other...

'This includes...refraining from playing music or broadcasts that may encourage shouting, including if played at a volume that makes normal conversation difficult. This is because of the potential for increased risk of transmission, particularly from aerosol transmission.’
Over the last 2 days at @covidinquiryuk the NHS has shown its dark & ugly side
There was never going to be an apology from IPC guidance authors whose guidance drove disproportionately high rates of death & COVID19 in non-ICU HCWs & huge rates of nosocomial SARS2, but…
/1
the level of obfuscation, evasion & incompetence on display from those tasked with keeping HCWs safe, is jaw dropping
I was one of the lucky ones: my NHS Trust ALWAYS provided HCWs with FFP3 when caring for those with COVID19 - my IPC remained precautionary
As a result…
/2
by Dec 2020 the number of consultant staff working on Covid wards testing positive was: 0
🚨The ONLY deviation from national guidance was universal FFP3!
The last & most vital line of defence - FFP3 - *is life saving* @SMHopkins
TL/DR in evidence to @covidinquiryuk, CH stated SARS2 transmission is via large droplet & fomites
But:
Following peer review triggered changes 6 Jul 2022, CH's own work stated that SARS2 transmission is via 'fine aerosols & respiratory droplets, & to a lesser extent...fomites'
Why omit the empirical truth that SARS2 transmission occurs importantly via the airborne [aerosol inhalation] route?
Why do this, particularly as David Heymann's 13th Oct 2023 evidence to the PI clarified the @WHO position:
WHO knew SARS2 transmission was via aerosols, Jan 2020
'Arguably the most fundamental misstep in the UK response was the presumption that covid would be an unstoppable flu-like wave'
This
underpinned the early (Chris Whitty) position on T&T, & the Vallance view on 'herd immunity' (later air-brushed)'
Aside
Early SAGE minutes clarify the UK rationale for stopping community SARS2 testing: it was deemed unnecessary because with rapidly increasing case numbers there was no point in testing, as there were insufficient personnel to contact trace
Good to know whose plan this was
'But there was an alternative'
'This led us to question...though we found ourselves quietly dismissed as not understanding the science'
'Ironically, the pride in our science & our capabilities, slowed our ability to learn lessons from other countries'
