Face Shields To Help Protect Yourself

Nov 11,2020

What is a face Shields?

A face shield, an item of personal protective equipment (PPE), aims to protect the wearer's entire face (or part of it) from hazards such as flying objects and road debris, chemical splashes (in laboratories or in industry), or potentially infectious materials (in medical and laboratory environments).

Functions:

  •  Anti-spray
  •  Anti-fogging
  • Anti-smoke
  • Oil splash proof
  • Anti-exhaust

When should you wear a face mask?

CDC recommends all people 2 years of age and older wear a mask in public settings and when around people who don't live in your household, especially when other social distancing measures are difficult to maintain. COVID-19 can be spread by people who do not have symptoms and do not know that they are infected.

Are face shields effective?

  • A 2014 study showed that when tested against an influenza-infused aerosol from a distance of 18 inches away, a face shield reduced exposure by 96% during the period immediately after a cough. The face shield also reduced the surface contamination of a respirator by 97%.

Are face shields good for everyday use?

  • CDC does not recommend wearing face shields for normal everyday activities or as a substitute for cloth face coverings. However, some people may choose to use a face shield when they know that they’ll be in sustained close contact with others. In these cases, it’s best to wear a mask underneath the face shield and maintain physical distancing when possible. This will help minimize the risk of infection since face shields have openings at the bottom.
  • The CDC also says if face shields are used without a mask, they should wrap around the sides of the wearer’s face and extend to below the chin. The CDC does not recommend plastic face shields for newborns or infants.

How to keep a face shield clean

As mentioned earlier, masks absorb droplets when we sneeze or cough. Face shields don’t. Dr. Esper stresses that should you decide to wear a face shield, you’ll need to sanitize it frequently.

“We know this virus likes to live on plastic a lot better than it likes to live on porous materials like cloth, paper or cardboard,” he says. So again, clean your face shield once you take it off. You can sterilize it with an antibacterial wipe, alcohol pad or soap and water.

If your face shield cracks or becomes damaged, don’t continue to use it. Many places offer face shields in bulk. This makes it easier for you to pitch the damaged face shield and move on to the next one.
