What does the marking z87+ designate in workplace safety equipment?

• A. High impact rating
• B. Noise rating
• C. NASI/OSHA designation for safety glasses
• D. Electrical resistance rating

Answer: (C)

The marking shows compliance with a specific eye‑protection standard. Z87+ means the eyewear meets the ANSI/ISEA Z87.1 standard for safety glasses used in workplaces, and the plus sign indicates it has passed high-velocity/high‑impact testing beyond the basic requirements. This designation is recognized by OSHA as proof the glasses offer approved eye protection. It’s not related to noise levels or electrical resistance, which is why the best interpretation is that it’s an ANSI/OSHA designation for safety glasses, with the added note of higher impact resistance.
