Face masks are currently required on the Boston University Shuttle and in healthcare spaces, including the Occupational Health Center.
While masks are no longer required in most University spaces, face masks remain an invaluable tool for public health and preventing transmission of disease. A high-quality mask worn correctly and consistently will significantly reduce the risk of viral transmission even if others around you are not masked.
Face masks should:
- Fit snugly but comfortably against the sides of the face and cover the nose, mouth, and chin
- Fasten securely with ties or ear loops
- Include multiple layers of fabric
- Allow for breathing without restriction
- Be able to be laundered without damage or change to shape, if they are the reusable type
- Allow breaths to be taken through the mask, not around it! (see “How to Wear Your Mask” below)
How to Wear Your Mask
In order to be an effective tool to prevent the spread of illnesses like COVID-19, any facial mask must be worn correctly and consistently. Facial masks should ideally consist of at least three layers of material (3-ply) and cover the chin, mouth, and nose. To ensure a snug fit, after washing your hands and placing your mask on, place your hands around your mask and be sure that air is passing through the mask and not around the sides of the mask.
Types of Masks
- N95s, KN95s, KF94s, FFP2s, and other similar masks that provide enhanced filtration offer the greatest level of protection.
- Surgical or high-grade medical masks are almost always made of three layers and offer greater protection than cloth masks when worn properly or used with a cloth mask.
- Three-ply cloth masks offer good protection and are more readily available.
- Gaiters, bandanas, neck fleeces, scarves, and masks with exhalation valves should not be used.
- Regardless of which type of mask is used, it must be worn consistently and have a snug fit!
