ANSI Z87.1 is a standard established by the American National Standards Institute that outlines the requirements for eye and face protection in various environments. It specifies performance criteria for safety glasses, goggles, and face shields to ensure they provide adequate protection against hazards like impact, heat, and chemicals. This standard is essential for workplaces where there is a risk of eye injury, such as construction sites, laboratories, and manufacturing facilities. Products that meet ANSI Z87.1 standards are marked with a specific label, indicating they have been tested for safety and effectiveness in protecting the eyes.
