Technical Vault: KleenGuard™ Nemesis™ Small Safety Glasses 38474

The KleenGuard™ Nemesis™ Small Safety Glasses 38474 are reusable, non-prescription industrial safety glasses engineered for workers with smaller, slimmer, or narrower facial profiles. This configuration combines a clear polycarbonate lens, scratch-resistant hardcoat, compact 8.25 base-curve wraparound frame, reinforced integral nosepiece, wider bridge, soft-touch temples, ultraviolet filtration, high-impact protection, and an included neck cord.

The SOSCleanroom catalog identifies this version as clear uncoated to distinguish it from the separate clear anti-fog SKU. SKU-specific product records identify the lens as hardcoated or scratch resistant. The technically accurate interpretation is therefore clear scratch-resistant hardcoat without KleenVision™ anti-fog treatment, rather than a completely untreated polycarbonate lens.

This Technical Vault entry consolidates the product’s identity, small-fit geometry, lens construction, coating distinction, protective classifications, fit verification, fogging considerations, PPE compatibility, controlled-environment guidance, cleaning requirements, inspection criteria, storage practices, and use limitations. Final selection must be based on the employer’s documented hazard assessment and confirmation that the frame provides correct coverage and retention for the individual wearer.

The term “uncoated” is commonly used in distributor and catalog naming to distinguish this SKU from the separately offered anti-fog version. However, SKU-specific manufacturer and distributor records also describe the 38474 lens as hardcoated or scratch resistant.

For accurate technical presentation, the lens should be described as a clear polycarbonate lens with scratch-resistant hardcoat and without KleenVision™ anti-fog treatment. This wording preserves the established catalog distinction while avoiding the inaccurate implication that the lens has no surface treatment of any kind.

The 38474 and 38478 models use the same general Nemesis Small fit platform but differ in lens treatment and catalog positioning. Selecting the correct version depends largely on fogging conditions, cleaning procedures, and operational requirements.

The Nemesis Small frame is intended for wearers whose facial width, temple spacing, bridge dimensions, or head size are not adequately accommodated by standard universal-size safety glasses. Oversized eyewear may sit too far from the face, create excessive side gaps, slide during movement, or interfere with other protective equipment.

Ansell describes the model as fitting smaller and slimmer heads without extensive adjustment. The compact frame, stronger nosepiece, wider bridge, and soft-touch temples are intended to improve lens position, retention, comfort, and peripheral coverage.

Protective performance depends on the eyewear remaining correctly positioned relative to the eyes and facial contours. A compliant lens that does not fit the wearer correctly may shift, create unintended openings, obstruct vision, interfere with other PPE, or encourage repeated adjustment.

• Helps keep the lens centered in front of both eyes
• Reduces excessive frame width on smaller wearers
• Helps limit side and lower-edge coverage gaps
• Reduces downward slippage during normal movement
• Helps reduce repeated face and eyewear touching
• Can improve compatibility with masks, hoods, hard hats, and earmuffs
• Supports more consistent eyewear use throughout the work shift

1. Place the glasses on the wearer without excessively spreading the temples.
2. Confirm that the integral nosepiece sits securely without painful pressure.
3. Verify that the lens is centered in front of both eyes.
4. Inspect the side and lower lens edges for excessive openings.
5. Ask the wearer to look upward, downward, and from side to side.
6. Confirm that the frame does not obstruct required vision.
7. Ask the wearer to bend, turn, walk, and perform representative work movements.
8. Verify that the glasses remain secure without frequent adjustment.
9. Repeat the assessment with all required hard hats, masks, respirators, hoods, face shields, and hearing protection.

Current Ansell Nemesis Small documentation identifies the platform as manufactured to comply with ANSI/ISEA Z87.1-2020 and as Z87+ high-velocity impact rated. The Z87+ designation identifies high-impact performance under the applicable requirements for spectacle-style occupational eye protection.

Older SKU-specific documents and distributor records may use ANSI Z87.1+, ANSI Z87.1-2010, or similar legacy wording. Current product content should use ANSI/ISEA Z87.1-2020 as the principal family-level reference while retaining legacy references only for historical, procurement, or lot-specific document review.

The Z87+ designation addresses impact performance under the applicable spectacle requirements. It does not establish sealed protection or suitability for every workplace eye and face hazard.

• Impact certification does not make the glasses chemical-splash goggles
• Wraparound coverage does not make the eyewear dust-tight or gas-tight
• A face shield may be required in addition to primary eye protection
• Welding, brazing, cutting, and laser work require specialized optical filters
• Fine dust, aerosols, splash, or multidirectional hazards may require greater enclosure
• Correct individual fit must be verified before assignment
• Damaged eyewear must be removed from service regardless of its original rating

Polycarbonate is widely used in occupational safety eyewear because it combines low weight, optical transparency, impact resistance, and ultraviolet filtration. The clear configuration is intended primarily for normally illuminated indoor environments and tasks where natural color recognition is important.

The hardcoat is intended to improve resistance to routine surface abrasion and preserve optical clarity during normal industrial use. It does not make the lens scratch-proof or immune to damage from grit, metal particles, abrasive wiping, chemical attack, or improper storage.

• Remove loose particles before contacting the lens surface
• Avoid dry wiping when dust, grit, or metal particles are present
• Use soft optical tissues, microfiber cloths, or approved cleanroom wipes
• Do not use scouring pads, shop towels, or rough paper products
• Do not place the lens directly against tools, fasteners, or abrasive surfaces
• Replace eyewear when scratches interfere with vision or hazard recognition

SKU 38474 does not include the KleenVision™ premium anti-fog coating. Fogging may occur when warm, moisture-containing air contacts a cooler lens and condenses into droplets that reduce visibility.

Fogging risk increases in high humidity, rapid temperature changes, physically demanding work, or when masks, respirators, hoods, and face coverings direct warm air toward the lens. Where these conditions are routine, the separately offered anti-fog configuration should be evaluated.

• Select SKU 38474 for stable environments where fogging is not a recurring concern
• Evaluate the anti-fog version for humid or temperature-variable operations
• Consider respirator and mask airflow when selecting the lens treatment
• Do not rely on repeated removal or wiping as the primary fog-control method
• Do not apply unapproved aftermarket anti-fog chemicals
• Use a purpose-designed anti-fog SKU where fogging affects safety or productivity

The clear lens is intended for normally illuminated indoor environments where tinted eyewear could reduce task visibility or interfere with color recognition. It does not provide sunglass-style glare or brightness reduction.

• Suitable for indoor manufacturing and assembly
• Supports laboratory, inspection, and quality-control work
• Supports packaging, warehousing, and material handling
• Appropriate where accurate color recognition is required
• Suitable for normally illuminated facility and maintenance areas
• May be unsuitable for intense exterior brightness without additional evaluation
• Does not replace specialized optical protection for welding or laser radiation

The 8.25 base-curve lens follows the general contours of the face and extends protection toward the sides of the eyes. This high-wrap geometry offers broader peripheral coverage than a flatter conventional spectacle lens.

The practical protection provided by the wraparound design depends on correct fit and position. A frame that is too wide may sit away from the face or shift during movement. The smaller Nemesis frame is intended to maintain closer positioning on narrow facial profiles.

Ansell identifies the nosepiece as integral to the lens and describes the Nemesis Small platform as having a stronger nosepiece and wider bridge for enhanced comfort. The integrated structure eliminates a separately attached adjustable nose pad while providing a stable frame contact point.

• Supports consistent lens positioning
• Helps distribute contact pressure across the nose
• Reduces the number of separate adjustable components
• Provides a durable sport-style construction
• Must be inspected for cracks, deformation, roughness, or sharp edges
• Must fit securely without painful pressure or excessive movement

The temple system uses soft-contact surfaces intended to improve wearer comfort and retention. SKU-specific listings also describe a ratchet-hinge temple design, which may assist with lens-angle positioning.

• Soft temple contact helps reduce pressure during prolonged wear
• Slip-resistant contact surfaces support secure positioning
• Compact temple geometry accommodates smaller head dimensions
• Ratcheted positioning may assist lens-angle alignment
• Temple position must be checked with hard hats and hearing protection
• Loose, cracked, or deformed temples require product replacement

Safety eyewear that sits too wide, slides, pinches, obstructs vision, or repeatedly fogs is more likely to be removed or incorrectly positioned. Correct sizing and comfortable retention can support more consistent compliance with workplace eye-protection requirements.

• Manufacturing and production operations
• Assembly, inspection, checking, and quality control
• Laboratory and technical work
• Packaging, picking, and material handling
• Warehousing, shipping, and receiving
• Construction and facility maintenance
• Transportation, automotive, aviation, and fleet maintenance
• Utilities and equipment servicing
• Indoor work requiring clear lenses and natural color recognition
• General occupational eye-protection programs
• Visitor and contractor safety programs requiring small-fit eyewear
• Safety programs requiring a dedicated narrow-frame option
• Controlled-work areas where the product is approved by facility procedure

Safety glasses must be evaluated as part of the complete PPE system. Hard hats, respirators, masks, earmuffs, hoods, bouffants, face shields, and protective garments can alter eyewear position or interfere with seals and contact surfaces.

• Confirm that the frame sits securely without excessive side openings
• Ensure temples do not cross tight-fitting respirator sealing surfaces
• Verify that disposable-mask positioning does not displace the eyewear
• Check whether mask or respirator airflow causes lens fogging
• Ensure earmuff cushions remain properly seated
• Confirm hard-hat suspension components do not push the glasses downward
• Verify compatibility with hoods, bouffants, and face coverings
• Check that face-shield brackets do not contact or displace the frame
• Confirm secure fit during representative work movement
• Do not force the glasses over prescription eyewear unless specifically evaluated

The employer should identify the source, direction, frequency, duration, and severity of each eye hazard before selecting protection. Spectacle-style eyewear may be suitable for general impact and particle exposure but may not provide sufficient enclosure for liquid splash, fine dust, aerosols, or multidirectional hazards.

Industrial safety certification and cleanroom suitability are separate determinations. ANSI/ISEA impact compliance does not establish sterility, ISO cleanroom classification, low particle release, low outgassing, disinfectant compatibility, or suitability for aseptic processing.

The small-frame geometry may help reduce slippage and repeated adjustment for workers with narrower facial profiles. However, the lack of premium anti-fog treatment should be considered where masks, respirators, hoods, high humidity, or temperature changes could cause visibility loss and face-touch behavior.

• Confirm correct individual fit before assigning the eyewear
• Evaluate fogging risk under the actual gowning and environmental conditions
• Assign eyewear by employee or controlled area when practical
• Stage cleaned eyewear on the designated clean side of the gowning process
• Handle the glasses by the temples rather than the lens
• Complete fit adjustments before entering the critical work zone
• Do not place eyewear directly on benches, carts, gowning seats, or critical surfaces
• Do not transfer glasses between uncontrolled and controlled areas without approved cleaning
• Use only facility-approved cleaners and compatible low-lint wipes
• Inspect for haze, residue, scratches, frame damage, and retained contamination
• Define actions for dropped, displaced, contaminated, damaged, or fogged eyewear
• Upgrade to an anti-fog model when condensation causes repeated adjustment or removal

1. Inspect the eyewear before beginning the gowning process.
2. Clean or disinfect the glasses under the approved facility procedure.
3. Stage the eyewear in the designated clean-side location.
4. Handle the glasses only by approved contact points such as the temples.
5. Don the eyewear at the step specified by the gowning SOP.
6. Confirm that the small frame sits securely and provides adequate coverage.
7. Complete nose and temple positioning before final glove donning when permitted.
8. Confirm compatibility with the mask, respirator, hood, bouffant, and face shield.
9. Evaluate whether the complete PPE configuration causes lens fogging.
10. Avoid touching or readjusting the glasses inside the critical work area.
11. Follow the defined deviation procedure if the eyewear is dropped, displaced, contaminated, or fogged.

1. Wash and dry hands or don clean gloves as required by the work area.
2. Inspect the lens for loose dust, grit, metal particles, dried residue, or abrasive contamination.
3. Remove loose particles using clean air or a gentle water rinse when permitted.
4. Apply an approved optical cleaner, mild soap and water, or another validated cleaning solution.
5. Wipe gently with a soft optical tissue, microfiber cloth, or approved cleanroom wiper.
6. Avoid excessive pressure and abrasive wiping.
7. Rinse where required to remove soap or cleaner residue.
8. Dry using a clean, soft, non-abrasive material.
9. Inspect the lens, hardcoat, nosepiece, temples, hinges, cord, and safety markings before reuse.

Do not assume that an aftermarket anti-fog spray, wipe, detergent, or coating is compatible with the 38474 lens. Unvalidated treatments may leave residue, create optical distortion, reduce scratch resistance, interact with disinfectants, or damage the polycarbonate surface.

• Use only treatments approved for polycarbonate safety eyewear
• Confirm compatibility with the existing hardcoat
• Evaluate residue and optical clarity after application
• Validate use under the facility cleaning and contamination-control procedure
• Do not use improvised household products
• Select the factory anti-fog SKU when persistent fogging is predictable

Inspect the eyewear before each use and after any impact, chemical contact, abnormal heat exposure, or cleaning process that could affect protection or optical performance. Remove the glasses from service when any condition could reduce fit, clarity, impact performance, or structural integrity.

• Cracked, chipped, warped, or deformed lens
• Deep scratches or abrasion that interferes with vision
• Persistent haze, clouding, distortion, or discoloration
• Damaged or visibly degraded hardcoat
• Cracked, sharp, or permanently deformed nosepiece
• Loose, cracked, bent, or deformed temples
• Loose or damaged ratchet hinges or fasteners
• Loss of secure fit during normal movement
• Excessive openings caused by incorrect sizing or frame deformation
• Illegible required safety markings
• Exposure to a significant impact event
• Chemical contact that may have degraded lens or frame components
• Residue that cannot be removed through the approved cleaning process
• Recurring fogging that prevents safe task performance

Store the glasses in a cool, clean, and dry location away from direct sunlight, excessive heat, abrasive materials, heavy objects, and chemical vapors. The coated lens and small-frame geometry should be protected from unnecessary contact and deformation.

• Use an individual case, sleeve, or designated storage compartment
• Do not store with sharp tools, fasteners, metal parts, or abrasive materials
• Do not place heavy objects on the lens or temples
• Avoid prolonged storage in hot vehicles or near process heat
• Keep away from solvent, adhesive, fuel, and cleaning-chemical vapors
• Store cleaned eyewear separately from contaminated PPE
• Do not allow the lens to rest directly against rough surfaces
• Do not force the small frame around oversized objects during storage
• Use the neck cord as a temporary retention aid rather than long-term storage

Ansell lists the Nemesis Small product family as eligible for the RightCycle™ Program. Actual eligibility, contamination restrictions, collection methods, geographic availability, minimum quantities, and accepted product conditions should be confirmed with the current program before the glasses are placed into a recycling stream.
