Updated guidance on masks/face coverings

As you are aware we are constantly updating our guidance in respect Covid 19 and the following updated guidance on the wearing of masks the following update has been received.

Updated guidance from SAGE:

“Face coverings and face masks control the source of the virus and provide important mitigation against all routes of transmission. They also provide a degree of protection against exposure. The effectiveness of face coverings improves with quality of design (multilayer masks are better than single layer), a snugger fit on the face, and correct usage with both nose and mouth covered (high confidence).A better level of mitigation could be achieved through specifying higher performance face coverings and masks, and this should particularly be considered in settings where people are more vulnerable to the consequences of the disease and/or are more likely to be infectious. It may be necessary to extend the use of face coverings to a wider number of settings (e.g. workplaces and education) where they are not currently mandated. This is important even when people are more than 2m apart, as correctly worn face coverings also reduce the emission rate of small aerosols.”

WHO guidance:

“Homemade fabric masks of three-layer structure (based on the fabric used) are advised, with each layer providing a function: 1) an innermost layer of a hydrophilic material 2) an outermost layer made of hydrophobic material 3) a middle hydrophobic layer which has been shown to enhance filtration or retain droplets. Factory-made fabric masks should meet the minimum thresholds related to three essential parameters: filtration, breathability and fit. Exhalation valves are discouraged because they bypass the filtration function of the fabric mask rendering it unserviceable for source control.”

Please ensure you have read the above thoroughly and that you make sensible and informed decisions to keep yourself and others safe.
