A large percentage of eye injuries are caused by direct contact with chemicals. These injuries often result from an inappropriate choice of personal protective equipment, that allows a chemical substance to enter from around or under protective eye equipment. Serious and irreversible damage can occur when chemical substances contact the eyes in the form of splash, mists, vapors, or fumes. When working with or around chemicals, it is important to know the location of emergency eyewash stations and how to access them with restricted vision.
When fitted and worn correctly, goggles protect your eyes from hazardous substances. A face shield may be required in areas where workers are exposed to severe chemical hazards.
Personal protective equipment devices for chemical hazards:
Safety goggles protect the eyes, eye sockets, and the facial area immediately surrounding the eyes from a variety of chemical hazards. Goggles form a protective seal around the eyes, preventing objects or liquids from entering under or around the goggles. This is especially important when working with or around liquids that may splash, spray, or mist.
Safety goggles may incorporate prescription lenses mounted behind protective lenses for individuals requiring vision correction. Take time to consider specific lens, frame, and ventilation options when selecting safety goggles.
Safety goggles lenses are designed and tested to resist moderate impact.
Safety goggle frames must be properly fitted to the worker's face to form a protective seal around the eyes. Poorly fitted goggles will not offer the necessary protection.

Ventilated goggles allow air circulation while providing protection against airborne particles, dust, liquids, or light.
Heat-reflective and wire-screen face shields are intended to shield the entire face from a range of heat hazards. Specific hazards associated with heat include high temperatures, splash from molten metal, and hot sparks. Face shields are considered secondary protectors to be used in addition to primary protection such as safety spectacles or goggles.
Face shield windows are made with different transparent materials and in varying degrees or levels of thickness. The thickness of the face shield window should be matched to the task. Window and headgear devices come in various styles in order to enable the worker to select the appropriate equipment.
Face shield windows extend from the brow to below the chin and across the entire width of the face.
Windows are available in both removable or lift-front designs:
Headgear supports the window shield and secures the device to the head.
