The Manufacture and Use of Barrier Masks

The French Standards Development Organization, AFNOR has produced a reference document that anyone can use to make"barrier masks". Intended for both mask manufacturers and the public, this document provides guidance on how to make masks for all healthy individuals and supplements the range of good hygiene practices that are essential for tackling the coronavirus epidemic. We feel this is a useful document that aids the UK collective efforts to combat COVID-19 so it is now available to download.
