PPE Selection - Heat: Safety Goggles
Goggle Protection 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.
Lenses
Safety goggles lenses are designed and tested to resist moderate impact.
  • Clear lenses:

    • Are available with removable lenses
    • May incorporate prescription lenses
    • Do not provide special protection against optical radiation

Frames
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 the eye sockets completely
    • Are available with direct or indirect ventilation
    • May be rigid or flexible

Ventilation
Ventilated goggles allow air circulation while providing protection against airborne particles, dust, liquids, or light.
  • Direct ventilation:

    • Resist direct passage of large particles into the goggle
    • Prevent fogging by allowing air circulation
Direct-ventilated goggles

  • Indirect ventilation:


    • Prevent fogging by allowing air circulation
    • Protect against liquid or chemical splash entry
Indirect-ventilated goggles

  • Non-ventilated goggles:


    • Do not allow the passage of air into the goggle
    • Prevent splash entry
    • May fog and require frequent lens cleaning
