5 points of advantages of using face shields
Answers
Explanation:
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. Although there are millions of potential users of face shields, guidelines for their use vary between governmental agencies and professional societies and little research is available regarding their efficacy.
Answer:
As opposed to face masks, face shields actually completely cover the face from the head extending all the way below the chin. As a result, it prevents you from touching your own face which isn’t exactly possible with face masks. Another argument in the favour of face shiels can be a recent study conducted to test the “Efficacy of Face Shields Against Cough Aerosol Droplets From a Cough Simulator”.
In the study, it was found that face shield reduced the inhalational exposure of the worker by 96 per cent within 18 inches of a cough. They can also prove to be far more comfortable and convenient to be worn by people when compared to face masks which may be restrictive and uncomfortable when used for very long hours.
