Extended-Cuff Protection and Gowning:
The 400 mm BioClean Nerva BNAL glove provides elbow-length coverage for tasks where the forearms may contact equipment, working surfaces, or incidental liquid splashes. Correct positioning and glove-to-garment overlap are important for maintaining protection.
- Elbow-Length Coverage: Extended glove length helps protect additional portions of the forearm compared with standard-length gloves.
- Gown-to-Glove Interface: Follow the approved arrangement of sleeve and glove cuff to minimize exposed gaps.
- Liquid Runoff: Position cuffs and arms to reduce the likelihood of liquid entering the glove opening.
- Beaded Cuff: Helps stabilize the extended cuff during movement.
- Workstation Movement: Confirm that the cuff remains correctly positioned during reaching, lifting, and equipment manipulation.
- Wet Handling: Avoid allowing chemicals to pool at cuffs or migrate underneath the glove.
- Glove Changes: Remove contaminated extended gloves in a controlled manner to prevent contact with clothing and skin.
- Material Compatibility: Confirm that chemicals contacting the sleeve and glove interface are compatible with all protective materials involved.
Extended Coverage Guidance: BNAL's elbow-length design provides additional forearm coverage, but the glove-to-garment interface must be managed as part of the facility's PPE program. Select the appropriate size, maintain secure cuff placement, and use a controlled removal procedure whenever chemical contact or contamination occurs.
AQL, Particle Performance and Glove Integrity:
BioClean Nerva BNAL includes manufacturer-documented barrier and cleanliness information to support controlled-environment selection. Freedom from holes and particulate cleanliness are different performance characteristics and should be assessed independently.
- AQL 1.5: Represents Performance Level 2 for freedom from holes under the applicable inspection procedure.
- Freedom-from-Holes Testing: The manufacturer references EN 374-2 for hole-quality testing.
- Typical Particle Count: Less than 1,200 particles/cm² at ≥0.5 µm.
- Particle Test Method: Manufacturer references IEST-RP-CC005.4.
- Target Thickness: Single-wall finger, palm, and cuff measurements represent manufacturer-published target values.
- Cleanroom Classification: Class 10 / ISO 4 describes intended application compatibility rather than a guarantee of contamination-free handling.
- Barrier Integrity: Gloves may become compromised through tears, punctures, stretching, abrasion, or chemical exposure.
- Particle Transfer: Actual contamination performance depends on handling, workstation conditions, glove changes, and contact surfaces.
- Receiving Controls: Verify the required product size, identification, lot information, and documentation according to facility procedures.
Cleanroom Performance Guidance: An AQL rating is a statistical manufacturing quality measure, not a guarantee that every glove is free from holes. Published particle measurements describe performance under defined test methods and do not replace controlled handling, glove inspection, or facility qualification procedures.
Chemical Permeation and Splash Protection:
BioClean Nerva BNAL is classified as PPE Category III and meets EN ISO 374-1 Type B (KPT) chemical protection requirements. Ansell publishes chemical permeation results for selected agents that can help determine suitability for laboratory chemical handling, cleaning, and incidental splash exposure.
The following examples are from the manufacturer-published BNAL chemical permeation summary. Results are for the tested concentrations and laboratory conditions and should not be interpreted as permitted glove-wear durations.

Chemical permeation performance varies by formulation, concentration, temperature, glove condition, and exposure method. Consult the complete manufacturer report before selecting gloves for the actual chemical being handled.
Chemical Protection Guidance: Breakthrough times represent laboratory permeation results under defined continuous-contact conditions. They are not recommended glove-wear times or guarantees of protection during actual use. In particular, the published results for 70% IPA, ammonium hydroxide, hexane, and concentrated sulfuric acid demonstrate why chemicals must be evaluated individually. Establish appropriate glove selection, replacement frequency, and exposure controls for the complete task.
Chemotherapy Drug and Sterility Limitations:
BNAL is intended for non-sterile cleanroom operations and selected chemical handling applications. Ansell does not identify this model as tested for chemotherapy drugs, and the glove is not supplied sterile.
- Non-Sterile: BNAL is not gamma sterilized or supplied in sterile pair packaging.
- Aseptic Procedures: Select an appropriately qualified sterile glove whenever the operation requires sterile presentation.
- Chemotherapy Testing: BNAL is not designated as tested for use with chemotherapy drugs.
- Hazardous-Drug Programs: Select gloves meeting the applicable chemotherapy testing and protection requirements for hazardous-drug handling.
- Double-Gloving: The manufacturer's outer-glove recommendation does not establish suitability for hazardous-drug use.
- Chemical Permeation: General chemical testing does not replace drug-specific chemotherapy permeation testing.
- Product Substitution: Do not replace a specified sterile or chemotherapy-tested glove with BNAL without appropriate assessment and approval.
Application Selection: BioClean Nerva BNAL is non-sterile and is not chemotherapy-tested. For aseptic processing requiring sterile gloves, choose a sterile cleanroom model. For hazardous-drug handling, select appropriately tested chemotherapy gloves supported by manufacturer drug-specific permeation documentation and the facility's PPE requirements.
Antistatic and ESD Considerations:
Ansell identifies BioClean Nerva BNAL as non-antistatic. Cleanroom compatibility and low particle contribution do not independently establish electrostatic charge dissipation or suitability for ESD-sensitive processes.
- Manufacturer Antistatic Classification: No
- ESD-Sensitive Components: Select qualified ESD-protective gloves where required.
- Personnel Grounding: Follow approved ESD wrist-strap, footwear, flooring, and workstation procedures.
- Glove Electrical Properties: Confirm required resistance and charge-control performance using appropriate qualification methods.
- Surface Contact: Consider electrostatic charging and particle attraction during repeated handling of insulating materials.
- Process Qualification: Evaluate electrostatic performance separately from sterility, chemical protection, and particle cleanliness.
Double-Gloving and Glove-Change Procedures:
Ansell recommends BioClean Nerva BNAL for consideration as an outer glove in double-gloving applications. The appropriate configuration depends on the facility's gowning procedure, chemical hazards, contamination controls, and required glove performance.
- Outer Glove: BNAL may be used as an additional outer layer when its non-sterile classification and chemical performance are appropriate.
- Inner Glove: Select a compatible inner glove based on the required task protection and cleanliness requirements.
- Fit: Check that the combined glove layers allow adequate movement without excessive stretching or bunching.
- Cuff Interface: Maintain appropriate coverage between gloves and cleanroom garment sleeves.
- Routine Changes: Establish time- or event-based replacement intervals within the facility SOP.
- Immediate Replacement: Replace gloves after punctures, tears, incompatible chemical exposure, or contamination events requiring removal.
- Task Changes: Change gloves at defined transitions between clean and contaminated operations.
- Removal: Peel gloves off carefully without snapping, allowing contaminated exterior surfaces to remain contained.
- Inner Glove Inspection: Check the inner glove after removing the outer layer and replace it if contaminated or compromised.
- Hand Hygiene: Follow the facility's hand hygiene requirements after removing gloves.
- Documentation: Incorporate glove-change triggers, layering requirements, and disposal procedures into approved work instructions.
Glove-Change Guidance: Establish replacement intervals based on contact conditions, material hazards, contamination requirements, and manufacturer performance information. Gloves should be changed immediately when damaged, visibly contaminated, or exposed to conditions outside the approved procedure. A double-glove configuration must provide the required protection for the actual task.
Latex-Free and Accelerator-Free Construction:
- Natural Rubber Latex-Free: Nitrile material does not contain natural rubber latex proteins.
- Accelerator-Free: Formulated without added chemical accelerators commonly associated with certain contact sensitivities.
- Powder-Free: Avoids added powder that could contribute contamination during donning or handling.
- Operator Comfort: Chlorinated interior supports convenient application and glove changes.
- Allergy Considerations: Latex-free and accelerator-free construction can reduce exposure to selected allergens but does not eliminate every potential sensitivity.
- Process Compatibility: Review material requirements when handling sensitive chemicals, product-contact surfaces, or contamination-sensitive components.
Size Selection and Manufacturer Ordering Codes:
BioClean Nerva BNAL is available in five manufacturer sizes. The correct fit supports finger control, secure cuff positioning, and comfortable use during extended handling tasks.
