Q.

Is a valved mask safe to use?

We issue our workshop staff FFP 2 masks with a valve. We are now being told that the valved masked does not prevent the spread of the covid 19 virus as the valve allows the virus to escape.

Hi Arthur

New evidence keeps on being gathered, so the facts change on a daily basis, but yes, it does seem to make sense. If there is an exhalation valve on the mask, the virus can escape through this valve. Good luck and stay safe.
