Government guidance for lab working stipulates that “where you are already using PPE in your work activity to protect against non-COVID-19 risks, you should continue to do so… When managing the risk of COVID-19, additional PPE beyond what you usually wear is not beneficial. This is because COVID-19 is a different type of risk to the risks you normally face in a workplace, and needs to be managed through social distancing, hygiene and fixed teams or partnering, not through the use of PPE. The exception is clinical settings”.
