Protective eyewear must fit snugly without unduly interfering with the wearer's movements, according to the U.S. Department of Labor Occupational Safety & Health Administration. In addition, the eyewear must provide adequate protection against the presented safety hazards.
Distinct markings on the protective eyewear must facilitate identification of the manufacturer, states OSHA. Durability and ease of cleaning and disinfection are also minimum requirements for the eyewear. Comfort, as well as safe design and construction, are also mandatory. A person skilled in the procedure must fit the protective eyewear on the employee. Qualified optical personnel must fit prescription safety eyewear. To ensure a comfortable fit, eyewear with adjustable features is fitted on an individual basis. When fitted properly, safety eyewear forms a protective seal that prevents eye contact with chemical splashes, dust and other safety hazards.
Protective eyewear with optical or structural defects is prohibited, explains OSHA. Pitted lenses reduce vision and require replacement. In addition, deeply scratched lenses are prone to break and also require replacement. Headbands that are worn out, twisted or otherwise misshapen do not hold the eyewear in proper position. Headband replacement is required when the elasticity is reduced so much that the headband no longer functions properly.
