Remember the webinar on EPP and Covid-19 that we held some time ago?
WHO published a useful document with technical specifications for PPE.
The document provides guidance on quality, performance characteristics and related standards for PPE for use in COVID-19. It includes information on: surgical masks, non-surgical masks, gloves, goggles, face shields, gowns and N95 masks.
The document can be downloaded here: https://www.who.int/publications/i/item/WHO-2019-nCoV-PPE_specifications-2020.1.
