Queensland schools are being encouraged to increase natural airflow in classrooms, or hold lessons outdoors, when school resumes to help reduce COVID-19 transmission — but air quality experts say the measures do not go far enough.
The guidelines do not encourage schools to use carbon dioxide monitors — a proxy measurement for ventilation — to assess ventilation risks, or to install HEPA filters, which air quality experts have been strongly recommending.
Last year, ABC Radio Brisbane reported that a high school teacher had recorded a high-risk ventilation level more than four times the recommended level in his classroom, prompting fresh calls for ventilation audits.
