Face shields are personal protective equipment devices that are used by many workers (e.g., medical, dental, veterinary) for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids. Face shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment.
Getting the most benefit from a face shield
To get the most benefit from a face shield, the Following is recommend these three things:
1. Always wear a face shield with a mask
For Instance, those face shields give the most benefit when you wear them along with a face mask.
“Adding a face shield is the icing on the cake and confers protection to you, the wearer”.
2. Make sure your face shield fits properly
“The shield should come to the level of the chin or below in the front.
It should almost reach the ears on the sides and “there should be no gap between the forehead and the front of the shield unless there is a cover over the gap. Otherwise, a droplet could come through the gap and land on your face.”
3. Clean and disinfect your face shield after each use
The CDC Trusted Source suggests referring to the manufacturer’s instructions, if available.
If there are no instructions available, they suggest cleaning with a neutral detergent and warm water to remove any visible soiling, followed by a clean water rinse.
They then recommend disinfecting the face shield, preferably with a chlorine-based solution. Alcohol can damage plastic and glues over time. Also, it may remove any anti-glare or anti fogging properties.
Rinse again with clean water to remove any residue.
Air dry or use clean paper towels to remove any moisture.
