While it is fun to laugh at the idea, I don't think , to be accurate, that anyone has suggested cutting the doors in half as the headlines have it, even those 2% to 4% of doors on "problematic spaces" where it will prove difficult to increase the ventilation - it would be more like planing a bit off the bottom of them, and that would be a temporary last resort.
“Based on informal local authority feedback, we expect that relatively only a very small number of learning, teaching or play spaces will have persistently high CO2 levels,” the education secretary’s letter states.
"Scottish Government guidance, based on the current weight of expert advice, is that the primary focus of mitigating activity should be on regular CO2 monitoring and associated remedial actions to improve ventilation (i.e. the introduction of fresh air into spaces).
“Where this cannot be readily achieved, and CO2 readings remain high, air cleaning/filtration devices may exceptionally be used as a temporary mitigation to reduce risks in problematic spaces while more sustainable, ventilation-based solutions are implemented.
“The informal local authority feedback indicated that around 2-4% of spaces have so far fallen into that problematic category, equalling around 2000 spaces out of 50,000 learning, teaching and play spaces across all local authority school and ELC settings.”
