Protective Eye and Facewear Standard: Selection and Use
Eye and face injuries may be prevented by using the appropriate protective eyewear and facewear for the job. Appropriate protective wear must protect against the specific hazard presented, provide a comfortable and secure fit, and comply with CSA Standard Z94.3.1-09, "Eye and Face Protectors."Eye and face injuries may be prevented by using the appropriate protective eyewear and facewear for the job. Appropriate protective wear must protect against the specific hazard presented, provide a comfortable and secure fit, and comply with CSA Standard Z94.3.1-09, "Eye and Face Protectors." The following outlines the general categories of protective eyewear and facewear:
1. Spectacle Type Safety Glasses
Safety glasses have lenses that are impact resistant and frames that are far stronger than those of regular eyeglasses. "Plano" (non-prescription) or prescription safety glasses (for those who need corrective lenses) with permanently attached side shields must be worn by those who require protection against flying particles. Safety glasses must comply with CSA Standard Z94.3.1-09.
Safety glasses come in a variety of lens materials, shades and tints. Lens materials include glass, polycarbonate, or plastic. It should be noted that current glass material lenses do not meet the impact criteria in CSA Standard. Safety glasses intended for protection where a reduction of visible radiation or a moderate reduction of optical radiation are required must be opaque or have side protection with a shade number equal to or greater than that of the filter lens.
Use of prescription eyewear is recommended practice for workers who require corrective lenses and are exposed to eye hazards on a regular basis. “Over-the-glasses” protectors (oversized protectors designed to be worn over non-safety spectacles) should only be used for workers and visitors who require protection occasionally.
2. Safety Goggles
Safety goggles are devices contoured for full facial contact and are held in place by a headband or another suitable means and therefore offer greater eye protection than safety glasses.
Safety goggles are impact resistant and must meet the minimum requirements of CSA Standard Z94.3.1-09. Like safety glasses, they are available in a variety of tints and shades.
Safety goggles may have direct or indirect ventilation to protect against fogging. Goggles with direct ventilation allow heat and humidity to dissipate, but do not protect against splash hazards. Goggles with indirect ventilation are designed to protect against dust and splash hazards.
