What does the marking z87+ indicate on safety glasses?

• A. High impact resistance
• B. UV protection rating
• C. Chemical resistance rating
• D. NASI/OSHA designation for safety glasses

Answer: (D)

Z87+ marks are about meeting a safety standard for eye protection. It means the glasses conform to the ANSI Z87.1 standard, which OSHA uses to approve protective eyewear for workplace use. The plus sign indicates a higher level of impact resistance, showing they can withstand high-velocity impacts beyond the basic requirement. This designation is about safety performance and regulatory acceptance, not about UV protection or chemical resistance, which would be shown by other specs.
