SEND and specialist settings – additional operational guidance: coronavirus (COVID-19)
Check out at the GOV.UK Website the latest updates on wearing face coverings.
All I would ask you to consider is wearing a mask that is fluid resistant to support no sneezes or coughs passing through materials. And visors do not protect you fully you will need to wear a face covering to. Ensure the face coverings fits to the face across the nose with a nose wire and fits the face so no gaps. There are a lot of products on the market with CE Marks still with gapping sides my own opinion and would rather be safe with a fitted mask please take care we are not out of the woods yet.
