KleenGuard V30 Nemesis (25676) — clear-lens eyewear for facility work, with gowning discipline that reduces contamination behaviors
What this product is (manufacturer identity)
Manufacturer product information lists code 25676 (former code 3000354) as a clear-lens, black-frame Nemesis variant with %VLT 87–93 and packaging of 1 each/bag; 12 bags/case.
The Nemesis platform features a base curve of 8.25, a Flex-Dry nose piece to channel sweat and reduce slippage, and flexible temples for long-wear comfort. A neck cord is included for retention.
Cleanroom / controlled-environment fit
These are safety glasses intended for impact-rated eye protection in general facility and industrial contexts. In controlled environments, confirm whether your gowning SOP calls for open safety glasses versus sealed goggles. In higher-grade sterile manufacturing contexts (EU GMP Annex 1 Grade A/B), programs commonly require sterile eye coverings (goggles) as part of a fully enclosed gowning system.
Donning guidance: ISO first, then Annex 1 overlay
ISO operations mindset: control people + behavior to control contamination
- Stage eyewear before gowning begins: avoid carrying eyewear through uncontrolled areas after gowning starts.
- Don by temples only: treat the lens + face interface as "no touch."
- Fit check once, then hands off: repeated adjustments are a common particle-transfer event.
- Cleaning method qualification: validate wipe-down chemistry for polycarbonate to avoid haze and residue.
European Annex 1 overlay: Annex 1 expectations for Grade A/B commonly include sterile eye coverings (goggles). If your operation is Annex 1 governed, confirm sealed/sterile goggle requirements rather than using open safety glasses in critical zones.
Common failure modes
- Face touching / eyewear adjustment: transfers contamination to gloves, then to product-contact surfaces.
- Uncontrolled storage: eyewear placed on benches or carts becomes a contamination pickup point.
- Unqualified cleaners: can haze polycarbonate and leave films that drive more adjustments.
- Annex 1 mismatch: open safety glasses used where sealed/sterile goggles are required.
SOSCleanroom note about SOP's
The Technical Vault is written to help customers make informed contamination-control decisions. It is not your facility's SOP, batch record, or validation protocol.
Use these best-practice suggestions to strengthen your SOPs—not to replace them.
