What is face shield?

The laboratory is a place dedicated to experimental purposes and an indispensable part of the scientific path. However, while experimenters are conducting scientific experiments, there are many hidden "killers" such as foreign body impact, solvent burns, poisoning, etc. The eyes and face are the most vulnerable parts of the laboratory, so their protection is especially important. Face shield, a type of personal protective equipment (PPE), is designed 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 industry), or potentially infectious materials (in medical and laboratory settings). Depending on the type of use, the mask can protect the wearer from physical hazards, chemical splashes, or biohazards.

The face shield is constructed by installing a knob with teeth on each side of the elastic head clip, and a large curved thin curved transparent cover on the knob with teeth, and the transparent cover can be screwed on the face or the top of the head on the elastic head clip with teeth knob. It can be used with anti-drug masks, dust masks, work caps, to achieve the purpose of comprehensive protection.

Face shield is divided into welding mask, safety protection mask, medical protection mask, anti-toxic mask and radiation mask according to the different occasions of use.

Feature of face shield

a. Face shield is a hard, clear piece of plastic that is attached to the headband.

b. Face shields come in a variety of forms, such as disposable or reusable, but all provide a clear plastic barrier that covers the face.

c. Some materials are tougher than others, and some shields are more scratch resistant, thus extending the overall life of the face shield.

d. Optical clarity in plastic face shields is critical.

e. If possible, do not share your face shield with others.

f. If there are not enough face shields available for each person to assign their own, be sure to clean and disinfect your shield before sharing it with others.

g. For best protection, the face shield should extend forward below the chin and laterally to the ears, and there should be no exposed gap between the forehead and the headgear of the face shield.

h. Face shields may be worn voluntarily as general PPE or may be required depending on the hazard assessment of the work task to be performed.

i. The required face shield must comply with OSHA's 29 CFR 1910.133, which requires the use of eye and face protection when workers are exposed to eye or facial hazards (e.g., flying objects, molten metals, liquid chemicals, acids or corrosive liquids, chemical gases or vapors), or potentially harmful light radiation.

j. Most required eye and face protection devices in use today are designed, tested, and manufactured in accordance with American National Standards Institute (ANSI) American National Standard ANSI Z87.1-2010.

k. General purpose face shields are not required to meet ANSI standards and can be worn voluntarily.

l. Universal face shields are not a substitute for a face shield and should be worn with a face shield.

m. Universal face shields offer several advantages for protection against COVID-19, especially when worn with a face shield.
a) The face shields provide full protection and are virtually impossible to wear improperly.
b) They can be reused indefinitely.
c) They are easy to clean.
d) They reduce the likelihood of autoinoculation by preventing the wearer from touching their face.
e) The face shield should be cleaned at least once a day after use.

Things about face shield in the laboratory that you should know

a. Face shields do not provide complete eye protection, so goggles (goggles for chemical splash hazards; glasses for particle and splash debris hazards) need to be worn under the face shield.

b. Various procedures in the laboratory require laboratory workers to wear face shields as part of their personal protective equipment. For example, face shields and goggles are required when filling/dispensing liquid nitrogen.

c. It is the laboratory PI's responsibility to purchase and provide laboratory staff with face shields when PPE is required in the laboratory.

d. Refer to your laboratory standard operating procedures (SOPs) and hazard analysis to determine the specific PPE requirements for your laboratory tasks.

Note: Face shields with ANSI approved goggle assemblies are available.

Advantages and disadvantages of face shield

There are many advantages and disadvantages to wearing face shields. They are easy to use because they do not require a tight seal, and they can be secured to the head for increased comfort. They are also less disruptive to breathing than face masks or respirators, and can be used in combination with other PPE such as face masks. Masks can be produced cheaply and easily in large quantities and can be cleaned and reused without loss of effectiveness (however, it is recommended that the mask be disinfected after use). Because the mask does not visually obscure the wearer's face, facial expressions are not impeded, making it useful for people who rely on non-verbal communication such as lip reading.

Type of face shield

Face guard

A. Plastic face shield

Plastic face shields are becoming an increasingly common choice for workplace PPE solutions that provide full protection for the face and extremities while also acting as a barrier to the spread of germs. But there are actually various types of face shields on the market, each with their own advantages and disadvantages.

B. Disposable face shield

In many cases, disposable face shields are essentially headband masks that are made of more fragile, lower quality materials. The trick is in the name, these are not a permanent option, but they are a good choice if you need a visor occasionally. You can also get replacement visors for slightly more fragile but not completely disposable masks.

C. Food-grade face shield

The space where food is prepared is one of the hardest hit workplaces in a pandemic, which is why it's critical for many of them to step up their personal protective equipment game. For high-traffic food preparation areas, protecting ingredients from droplets from the mouth and nose is only part of the battle, which is why food-grade face shields add some hair protection to improve protection and safety.

D. Pivoting visor

While you can usually adjust or remove the visor easily, there is a form designed specifically for convenience. The pivoting visor allows you to rotate the screen at your leisure, perfect for mealtimes or moments when you need to trust your naked eye.

E. Wide visors

One of the main criticisms about plastic face shields is their lack of peripheral protection, which wider visors help remedy. They are the same as headbands or food-grade masks, only with a wider visor to protect more of the face.

F. Goggle-based masks

Some masks are designed with built-in goggles or operate with separate, specific goggles. These are designed to provide full eye protection while still offering the additional protection that a plastic face shield can provide.

Use of face shield

a. Simply wipe with alcohol or rinse with soap and hot water to make the face shield contamination-free again.

b. To avoid causing surface scratches, submerge the face shield in warm water to remove particles.

c. Add a mild liquid dishwashing detergent to reduce surface tension and allow the soapy water to disperse evenly over the surface.

d. A soft cloth or sponge can be used to gently clean the face shield.

e. Rinse the guard with water and dry with a soft cotton towel or microfiber cloth.

f. Remember that soap and water remove microorganisms from our hands, so it applies to your face shield as well.

g. You may feel the need to wipe or spray with a surface disinfectant, but these products will leave a visible residue that needs to be removed.

h. A 70% alcohol wipe will also disinfect and keep the surface of the plastic face shield clean, but it is critical to wash the mask to remove the bioburden before disinfecting.

i. Remember also that face shields are made of a variety of plastics and over time some masks may become brittle or cloudy after being disinfected with alcohol or other disinfectants. This may shorten the life of the mask.

j. It is acceptable to wipe the headband with 70% alcohol after cleaning.

k. Clean the dedicated face shield according to the manufacturer's instructions.

How to avoid damaging the face shield?

a. Avoid using household cleaners containing ammonia or products specifically formulated for cleaning surfaces of face shield with glasses. Cleaners such as these have the potential to damage plastic surfaces and cause permanent clouding of the surface.

b. Commercial cleaners containing any type of grit, including toothpaste, are also not recommended.

c. Avoid using paper towels, which can easily scratch the mask.
