Eye and face protection is one of the most important forms of Personal Protective Equipment (PPE) for employees in laboratories. It should be used to protect laboratory personnel from chemical, biological, and physical hazards, including flying particles, molten metal, broken glass, acid or caustic liquids, chemical liquids, chemical gases or vapors, or potentially injurious light radiation.

Goggles
Goggles, also called safety glasses or goggles, are protective eyewear that usually encloses the area around the eyes to prevent water, chemicals, or particles from striking the eyes. They are used in many industries, including chemistry laboratories and woodworking shops; people who work with power tools, such as drills or chainsaws; and snow sport athletes. They are also available in prescription strength for those who wear corrective lenses.
Goggle-style eye protection is the most basic form of PPE, and it consists of protective devices that sit snugly over the eyes. They are often worn by workers performing physical labor, such as in sawmills, welding shops, and factories. They are also often used in snow sports and swimming to help keep the eyes from being irritated by chlorine or flying balls.
They are also used for motorcycle riding and other activities in which the eyes may come into contact with dust, insects, or other objects. They are also frequently worn in laboratory and research environments in order to help the eyes adapt to exposure to high levels of light or radiation.
Most goggles have a strap that goes across the face and secures them in place. This allows them to be pulled up by the head when necessary, preventing them from falling out of the face in an accident.
There are several types of goggles, depending on the type of liquid or chemical they are designed to protect against. The main type is called a chemical goggle, which forms a seal around the eyes that can prevent sprays, mists, or vapors from entering the eye. Some goggles have a vent in the lens that allows air to flow through, reducing fogging.
A third category is indirectly vented goggles, which have a vent in the lens that lets air pass through but does not allow liquids or other objects to enter the eye. This is the best option for workers with moderate quantities of splashed liquids or fine dust.
All of these types of protective eyewear should be disinfected and cleaned according to the manufacturer’s instructions before storage or reuse. The lenses should be rinsed with a mild soap and water solution, then dried thoroughly and discarded if they have pits or scratches.

Face Shields
Face shields are a form of eye and face protection that is commonly used in industrial settings. They are designed to protect the eyes and face from impact, chemical splashes, glare, sparks, and other hazards. They are also used in medical and dental settings, where they are often paired with safety glasses or goggles.
A face shield can be made from a variety of materials. Some are constructed from plastic, while others are made of acetate or polycarbonate sheets. They are typically lightweight and can be custom-printed with logos or colors. They can also be used for a number of different tasks, including insulating workers from heat and protecting them from harmful UV rays.
Some of the advantages of face shields over face masks are that they’re easier to clean (a simple wipe with a disinfectant can remove germs) and they’re usually reusable. However, they can be difficult to wear in some cases due to vision distortion and foggy appearance, so they should be used in conjunction with other forms of eye and face protection – such as goggles or glasses – when possible.
Another important advantage of face shields is that they prevent the spread of germs through respiratory droplets. That’s because a shield extends down below your chin, making it less likely for infectious air particles to get inside your mouth or nose. This means they’re an excellent choice for medical, dental, and other healthcare workers who may have to regularly come into contact with the COVID-19 virus and its associated respiratory droplets.
Finally, some face shields protect your chin and sides from flying metal chips or chemicals. These shields are naturally curved to provide extra coverage and protection from these hazardous substances.
Despite their benefits, they are still considered inferior to face masks when it comes to preventing the transmission of droplets that could carry the coronavirus and other germs. Therefore, they should be used with a cloth face mask covering your nose and mouth.

Safety Glasses
The primary eye and face protection classes are goggles, face shields, and safety glasses. These eye and face protective devices protect you against hazards ranging from particles to molten metal and radiation.
They come in a variety of frame styles and lens shades. Still, they must meet specific criteria established by the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). In addition, the lenses must meet high-impact requirements.
These goggles are typically made of metal or plastic and have side shields that provide additional eye protection in front of the eyes. They may also have lenses that block out hazardous light sources.
Some safety goggles have air vents that help prevent vapors and fumes from entering the eye area. They are often paired with anti-fog coatings to keep your vision clear while working in a chemical environment.
Inspect your safety glasses and snow goggles before you use them. Look for scratches, dents, and any other damage that might affect the performance of the material.
The material used to make safety goggles and glasses can decay over time, especially if the materials are not regularly cleaned or replaced. These deteriorated parts can make the glasses less effective in protecting you from hazards and cause them to break down sooner.
While a pair of poorly maintained goggles can be dangerous, most workers are only exposed to very small amounts of chemicals. It is, therefore, generally considered safe to wear goggles or glasses all day if they are rated for safety by a reputable manufacturer.
For example, the ANSI Z87.1-2003 standard specifies that safety goggles must have at least a “U6” impact resistance rating. If the lenses don’t meet this standard, they must have a warning label that can be removed only by the person wearing the eyewear.

Welding Helmets
A welding helmet is a type of headgear used to shield the eyes and face from welding hazards. These include flying debris, ultraviolet rays, and heat generated during welding processes.
Welding helmets come in many different styles and feature a variety of features that make them comfortable to wear. Some models offer adjustable fore/aft viewing to provide a closer fit, while others feature an ergonomic design that reduces strain on the head and neck.
Helmets with auto-darkening lenses can be a great choice for welders who want the added safety of a dark lens when the arc strikes. These lenses can be adjusted to match the arc brightness of various welding processes. They also feature several sensors that help determine how much light enters the eye.
The most important factor when choosing a welding helmet is the amount of coverage it provides. Generally, the larger the lens shade, the better it will protect your eyes from the welding arc. A good rule of thumb is to select a shade that’s between 8 and 13 (the darker the shade, the greater the coverage).
Another feature to look for in an auto-darkening helmet is its ability to automatically adjust its shade when it detects the arc. This can save a lot of time because it eliminates the need for the welder to manually adjust the helmet’s shade.
Some auto-darkening helmets also feature a grind mode that allows them to double as grinding shields for weld prep and post-weld clean-up tasks. This feature is especially helpful for out-of-position welding activities.
Finally, some auto-darkening helmets are able to adjust their shade to reflect the color spectrum of the weld puddle, helping welders to see it more clearly. This can significantly reduce eye fatigue and improve welders’ ability to control the weld puddle.
Welding helmets can be purchased from a wide range of manufacturers, including some of the top names in the industry, such as Miller Electric, Lincoln Electric, Optrel, and 3M. Each of these brands has a high-quality line of helmets designed to help you perform your job better and stay safer.
