PPE Selection - Dust: Goggles

---

Safety goggles are intended to protect the eyes against dust hazards. Goggles form a protective seal around the eyes, preventing nuisance dust from entering under or around the goggles. Ventilation should be adequate, but well protected from dust entry.

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

• Lenses
• Frames
• Ventilation

Lenses

Safety goggles lenses are designed and tested to resist moderate impact. Fig. 1: Clear, Removable Lenses 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. Fig. 2: Eye Cup Goggles Eyecup safety goggles: Cover the eye sockets completely Are available with direct or indirect ventilation May be rigid or flexible Fig. 3: Cover Goggles Cover safety goggles: May be worn over corrective spectacles without disturbing the adjustment of the spectacles Are available in direct, indirect, or non-ventilated types May be rigid or flexible

Ventilation

Ventilated goggles allow air circulation while providing protection against airborne particles, dust, liquids, or light. Fig. 4: Direct-ventilated Goggles Direct ventilation: Resist direct passage of large particles into the goggle Prevent fogging by allowing air circulation Fig. 5: Indirect-ventilated Goggles Indirect ventilation: Prevent fogging by allowing air circulation Protect against liquid or chemical splash entry Fig. 6: Non-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
