• Z87-2+: Denotes prescription frames compatible with high-impact Rx lenses.
• D3, D4, D5: Highlight droplet/splash (D3), dust (D4), and fine dust (D5) qualifications for goggles or sealed eyewear.
• U scale: Indicates ultraviolet filter category, relevant for some lenses.
• W shade: Refers to the welding filter designation and associated shade number.
• R scale: Denotes infrared filter categorization.
• L scale: Marks visible light filtering or tint category, specifying scale value.
• H: Indicates smaller headform sizing.
• Manufacturer marks and symbols: Essential for tracing compliance and determining specific products.

Selecting eyewear with appropriate codes guarantees compliance with both ANSI standards and OSHA program requirements. Safety managers often retain manufacturers' specification sheets and product declarations referencing ANSI Z87.1-2020. This approach supports site protection plans and simplifies the purchasing process.

Applications of Z87 Safety Glasses

Z87 safety glasses deliver protection across industries where impact, splash, dust, or optical radiation pose vision risks. ASTM, ANSI, and ISEA standards provide the guidelines necessary for compliance, while OSHA's eye and face protection mandates (29 CFR 1910.133) ensure usage wherever threats may occur. Aligning eyewear features with specific hazards enables specifiers to enhance security effectively.

In the construction and demolition sectors, activities such as cutting and drilling produce fragments necessitating Z87+ lenses with side shields for extra protection. Tasks in dusty environments benefit from D4/D5 ratings which guard against particle exposure (OSHA 1926.102). Metal fabrication tasks like grinding or sawing also require Z87+ impact-rated glasses, with welding operations benefiting from filter shades tailored to exposure levels.

Chemical processing and lab environments demand D3-rated eyewear or sealed goggles for splash resistance. Combining them with a face shield is common in procedures with elevated splash risk (OSHA 1910.133; CDC/NIOSH Eye Safety). Healthcare contexts call for splash-resistant eyewear compatible with respirators to handle blood or body fluid exposure risks (CDC/NIOSH Eye Safety).

Utilities and electrical maintenance industries contend with arc-related radiation; eyewear compatibility with arc-flash ensembles is essential (NFPA 70E). Oil, gas, and petrochemical fields require Z87+ lenses equipped with D3/D4/D5 features to guard against windborne debris and corrosive mists, while anti-fog coatings preserve visibility.

Mining and quarrying demand robust eyewear due to high-velocity particles from blasting and crushing. Suitable options include impact-resistant glasses offering wraparound coverage (MSHA PPE guidance). Carpentry and woodworking need Z87+ models with dust control to mitigate sawdust exposure—sealed or foam-lined versions further reduce ingress (OSHA 1910.133).
