Safety Glasses Are Not a PPE Program
CFR reference: 29 CFR 1910.133 (general industry) · 29 CFR 1910.132 (PPE hazard assessment)
OSHA Z87.1 eye and face protection requirements, side shields, face shields for grinding and chemical handling, and the PPE hazard assessment — 29 CFR 1910.133.
OSHA 29 CFR 1910.133 is the eye and face protection standard. It requires employers to ensure that affected employees use appropriate eye or face protection when exposed to hazards from flying particles, molten metal, liquid chemicals, acids or caustics, chemical gases or vapors, or potentially injurious light radiation. The standard works in tandem with 1910.132 — the general PPE standard — which requires a written hazard assessment before PPE selection.
The hazard assessment is the first compliance step, and the most commonly missing one. Under 1910.132(d), the employer must assess the workplace to determine if hazards are present that necessitate PPE, select appropriate PPE based on the assessment, communicate selection decisions to affected employees, and verify by written certification that the assessment has been performed. The certification must identify the workplace, the person performing the assessment, the date of the assessment, and a statement identifying the document as a certification. Most small operations have safety glasses on the shelf and no written assessment anywhere. That is two citations — one under 1910.132 for the missing assessment, and one under 1910.133 for the unverified eye protection.
ANSI Z87.1 is the consensus standard OSHA references. Eye protection that meets the standard is marked Z87 (basic impact) or Z87+ (high-velocity impact) on the frame or lens. Without the marking, the eyewear is not OSHA-compliant. Reading glasses, prescription glasses without the Z87 marking, and "fashion" safety glasses bought off the rack at a hardware store often do not carry the marking — they look like safety glasses but do not meet the standard.
Side shields are required when the hazard assessment identifies impact, dust, or lateral particle hazards — which is most general industry operations. Wraparound safety glasses with frame designs that wrap toward the temples meet the requirement. Conventional flat-front glasses without side coverage do not. Snap-on side shields are an acceptable retrofit but tend to disappear within a week of use.
Face shields are secondary protection. Worn over safety glasses or goggles, they protect against face-level impact, chemical splash, and molten material. Grinding, chipping, and chemical handling routinely require both safety glasses and a face shield. The most common gap I see is a grinder with safety glasses but no face shield — grinding fragments routinely hit the cheek, neck, and lower forehead, all unprotected.
Welding lenses and helmets are governed by 1910.252(b)(2) under Subpart Q (welding). Shade numbers must match the process and amperage — shade 10 minimum for stick welding at moderate amperage, higher for higher amperage and TIG. Auto-darkening helmets are acceptable if they meet the standard and are set appropriately for the process. A welding helmet with the wrong shade is not compliant.
Prescription users present a recurring problem. Employees who wear prescription glasses cannot achieve compliance by putting safety glasses over their prescription eyewear unless those safety glasses are specifically designed for the over-glass fit and are Z87-rated. The compliant option is prescription safety eyewear with the Z87 marking — available through occupational health providers for around $80 to $200 per pair, often covered by the employer under 1910.132(h) (the OSHA-employer-pays rule for required PPE).
Corrective action: perform a written hazard assessment for every workstation. Document it with date and certifier. Replace any non-Z87 eyewear in service. Add side shields or replace with wraparound designs. Add face shields at grinding stations and chemical handling stations. Provide Z87-rated prescription eyewear for prescription users. Train annually on PPE selection, fit, and use — document it. Total cost: under $500 for a typical small operation, plus prescription eyewear for any wearer. Total time: one shift.
Almost every shop I walk into has safety glasses available. Very few have a written hazard assessment. About half the glasses in use are non-compliant — no Z87 marking, no side shields, or scratched to the point of impaired vision. Grinders are run in safety glasses without face shields. Welders use whatever helmet is on the shelf, regardless of shade or process. Prescription users wear their personal eyewear. The PPE is mostly there. The program around it is mostly not.
ANSI Z87.1 is the American National Standard for occupational eye and face protection. The Z87 or Z87+ marking on the frame or lens indicates the eyewear has been tested to that standard. Z87+ indicates high-velocity impact rating. OSHA 29 CFR 1910.133 requires eye protection to meet the ANSI Z87.1 standard.
When the hazard assessment identifies impact, dust, or particles flying laterally — which covers most general industry operations — eye protection must have side shields. Side shields can be integral to the frame or attached. Wraparound safety glasses meet the requirement; standard glasses with no lateral coverage do not.
A face shield is required as secondary protection (worn over safety glasses or goggles) when there is a risk of significant facial impact, chemical splash, or molten material splatter. Grinding, chipping, and chemical handling typically require both. Safety glasses alone are insufficient for face-level hazards.
