KleenGuard™ Nemesis™ Small Safety Glasses (38474) — fit-driven compliance, and how eyewear should integrate into cleanroom gowning
Why eyewear belongs in the contamination-control conversation
Eye protection is often treated as a pure safety decision, but in controlled environments it also becomes a contamination-control variable. Fogging drives face-touch adjustments, poor fit creates gaps, and inconsistent storage/handling causes "bring-in" risk. Eyewear selection should be tied to the same operational control logic that governs garments.
What this product is (and is not) in cleanroom terms
- What it is: industrial safety glasses designed for impact-rated eye protection where comfort and fit improve compliance.
- What it is not: a cleanroom-dedicated goggle system.
- How to decide: your ISO operations program and Annex 1 CCS should define allowed eyewear type, cleaning method, and handling rules.
Gowning integration — ISO-first, then Annex 1
ISO operations lens: keep touch points controlled
- Don once, adjust once: pre-fit in the gowning area, then avoid repeated adjustments after gloves are on.
- Manage fogging proactively: if fogging is routine, move to an anti-fog lens SKU or a goggle system approved for your area.
- Control storage: the neck cord helps avoid placing glasses on uncontrolled surfaces; however, cords themselves can become contamination vectors if dragged across garments or benches.
EU GMP Annex 1 lens
In Grade A/B contexts, sites commonly require higher-control face/eye systems (often cleanroom goggles or sterile options). If Nemesis Small eyewear is used, it is typically restricted to support zones where explicitly permitted by SOP and where cleaning/handling steps are defined and verified.
Specifications in context
| Attribute |
38474 |
Why it matters |
| SKU / Code | 38474 | Traceability for receiving, training, and standardization. |
| Lens | Clear polycarbonate | Clear lenses support indoor visibility. |
| Lens coating | Hard Coat (manufacturer basis); listed as "Uncoated" on site (no anti-fog) | If fogging is present, move to anti-fog SKU rather than repeated face-touch adjustments. |
| Base curve | 8.25 (manufacturer basis) | Wraparound geometry can improve peripheral coverage. |
| UV protection | 99.9% UVA/UVB/UVC | Relevant for outdoor transitions and bright-light tasks. |
| Standard | ANSI Z87.1+ | Aligns to typical EHS personal eye protection programs. |
| Materials | Polycarbonate lens/nose; nylon frame/temple; TPR temple pads | Material mix matters for wipe-down compatibility. |
| Case unit | 12 glasses per case | Supports standardized issue/replace cycles. |
Best-practice donning technique
- Pre-stage clean: define wipe-down chemistry, wipe type, and method before introducing into controlled areas.
- Don before sterile gloves: reduces glove-to-face contact and adjustment risk.
- Fit check once: confirm temple placement once, then avoid repeated adjustments.
- Manage fogging correctly: move to anti-fog eyewear or approved goggles rather than repeatedly touching or lifting eyewear.
- Control storage: store in a controlled container/location defined by SOP.
Common failure modes
- Fogging → face touching: upgrade to anti-fog SKU or approved goggles.
- Poor fit on small faces: standard frames gap; "Small" sizing reduces the need for constant adjustment.
- Uncontrolled set-down: placing eyewear on uncontrolled surfaces undermines wipe-down discipline.
- Chemistry damage: aggressive solvents can craze plastics; validate wipe-down chemistry compatibility before rollout.
SOSCleanroom + Ansell (KleenGuard) — continuity matters
As KleenGuard transitions under Ansell's global protection platform, SOSCleanroom continues focusing on documentation-first support: consistent SKUs, manufacturer basis sheets, and practical technique guidance that reduces contamination behaviors during real shifts.

SOSCleanroom note about SOPs
The Technical Vault is written to educate customers and improve day-to-day handling technique. It is not your facility's gowning SOP, batch record, or validation protocol.
If you adopt any technique guidance here, treat it as a starting template: review, approve, and qualify it for your materials, disinfectants, acceptance criteria, and work practices.
