Thinking you'd have to read the ANSI Z87 to find the specifics. The glasses will not say Z133. they will be simply stamped ANSI Z87
ANSI Z87.1 Safety Glasses Standard
The ANSI Z87.1 standard outlines essential requirements for safety glasses, particularly regarding side protection.
Side Protection Requirements
- Mandatory Side Protection: Safety glasses must include side protection when there is a risk of hazards from flying objects.
- Acceptable Options: Detachable side shields, such as clip-on or slide-on types, are permitted as long as they meet the ANSI Z87.1 standard.
Importance of Side Shields
Side shields enhance the overall protection of safety glasses by preventing debris and particles from entering the eye area from the sides. This is crucial in environments where flying objects are a risk, such as construction sites or manufacturing facilities.
Protective eye and face protection devices must comply with any of the following consensus standards:
1910.133(b)(1)(i)
ANSI/ISEA Z87.1-2010, Occupational and Educational Personal Eye and Face Protection Devices, incorporated by reference in § 1910.6;
1910.133(b)(1)(ii)
ANSI Z87.1-2003, Occupational and Educational Personal Eye and Face Protection Devices, incorporated by reference in § 1910.6; or
1910.133(b)(1)(iii)
ANSI Z87.1-1989 (R-1998), Practice for Occupational and Educational Eye and Face Protection, incorporated by reference in § 1910.6;
To meet the ANSI Z87.1 standard, eyewear must provide adequate lateral coverage. This can be achieved through:
- Removable Side Shields: These can be added to standard safety glasses to enhance protection.
- Integrated Wrap Frames: These frames are designed to provide a snug fit around the eyes, offering additional side protection without the need for separate shields.
