Impact Hazards: Safety Goggles
Safety
goggles are intended to shield the wearer's eyes from impact
hazards such as flying fragments, objects, large chips,
and particles. Goggles fit the face immediately
surrounding the eyes and form a protective seal around
the eyes. This prevents objects from entering under or around the goggles.
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.

| 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.

Direct ventilation:
- Resist direct passage of
large particles into the goggle

Indirect ventilation:
- Prevent fogging
by allowing air circulation
- Protect against liquid or
chemical splash entry
