Heat injuries may occur to the eye and face when workers are exposed to high temperatures, splashes of molten metal, or hot sparks. Protect your eyes from heat when workplace operations involve pouring, casting, hot dipping, furnace operations, and other similar activities. Burns to eye and face tissue are the main concern when working with heat hazards.
Working with heat hazards requires eye protection such as goggles or safety spectacles with special-purpose lenses and side shields. However, many heat hazard exposures require the use of a face shield in addition to safety spectacles or goggles. When selecting personal protective equipment, consider the source and intensity of the heat and the type of splashes that may occur in the workplace.
Personal protective equipment devices for heat hazards:
Safety spectacles with side shields are used as primary protection to shield the eyes from heat hazards. To adequately protect the eyes and face from high temperature exposure, use safety spectacles in combination with a heat-reflective face shield.
The frames of safety spectacles are constructed out of metal and/or plastic and can be fitted with either corrective or plano impact-resistant lenses. Side shields are incorporated into the frames of safety spectacles when workplace operations expose workers to angular impact hazards. Consider each component of safety spectacles when selecting the appropriate device for your workplace.
The lenses of safety spectacles are designed to resist moderate impact from flying objects and particles.
Prescription (Rx) Lenses:
Special Purpose Lenses:
The safety spectacle frames must fit comfortably and correctly to offer the necessary protection.
Side shields provide angular protection from impact hazards in addition to frontal protection.
Flatfold or Semi Side Shields:
Full (cup) Side Shields may be:
Safety goggles are used as primary protection to shield the eyes from heat 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 molten metals that may splash.
When employees are exposed to high temperatures, additional protection beyond that offered by primary protectors may be required. Use safety goggles in combination with a heat-reflective face shield for severe temperatures exposure. Consider specific lens, frame, and ventilation options when selecting safety goggles.
Safety goggles lenses are designed and tested to resist moderate impact.
Special Purpose Lenses:
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.
Eyecup Safety Goggles:
Cover Safety Goggles:
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 Temovable or Lift-front Designs:
Headgear supports the window shield and secures the device to the head.
