Ansell BDOB-L BioClean-D™ Longer Length Overboots — Non-Sterile, Class 10 (ISO 4), 150/Case

Ansell BioClean-D™ BDOB-L are single-use, longer-length (500 mm) cleanroom overboots constructed from antistatic, low-linting CleanTough™ material. They are designed for controlled and critical environments where footwear control reduces particle transfer, and where a secure fit matters—featuring easy tie-fastenings at the top and ankle plus a slip-resistant sole. This SKU is supplied non-sterile and is commonly selected for ISO Class 4 / Class 10 garmenting programs requiring low shedding and repeatable donning.

Selection note: BDOB-L is non-sterile. If your SOP, customer requirement, or Annex 1 / aseptic practice requires sterile footwear, consider the sterile version: Ansell S-BDOB-L (Sterile).

About the Manufacturer:

BioClean-D™ garments are part of Ansell’s contamination-control apparel portfolio for controlled and critical environments. In this overboot design, the manufacturer emphasizes: low-linting CleanTough™ construction, static-dissipative behavior, and practical closures (top and ankle ties) to reduce footwear-related contamination transfer during entry/exit and routine movement.

BDOB-L Features:

Longer length (500 mm) for improved lower-leg coverage
Antistatic, low-linting CleanTough™ material
Tie-fastenings at the top and ankle to stabilize fit during movement
Slip-resistant sole to support safer cleanroom movement
Published particle-shedding performance (Helmke Drum Test) to support garment qualification

BDOB-L Benefits:

Footwear contamination control: helps reduce particle transfer from shoes into controlled areas when paired with a disciplined gowning boundary and approved entry procedure.
More stable fit: top and ankle ties help prevent slippage and “pumping” that can release particles during walking.
Lower-leg coverage: longer design helps protect the lower suit interface and reduces exposed garment-to-floor proximity risk.
Qualification-friendly: manufacturer-published test data supports QA review and incoming documentation sets.

Common Applications:

Controlled and critical environments requiring low shedding garments
Pharmaceutical, biotechnology, medical device, and laboratory workflows
Material handling and equipment prep in clean areas
Powder handling / compounding support where garment interfaces must stay controlled (process-dependent)

Best-Practice Use (Quick Guidance):

Don on the clean side of the gowning boundary: avoid stepping into overboots from a “dirty” zone after they are opened.
Control contact points: handle only inner surfaces where possible; avoid touching the outer sole and outer shin area with bare hands.
Seal the interface intentionally: bring the overboot up to full height and secure top and ankle ties to prevent slipping and reduce air pumping during movement.
Removal: remove slowly and deliberately; turn inside out as you doff to trap contamination and reduce particle release.
Follow your SOP: footwear selection, donning sequence, and disposal requirements should match your facility’s approved gowning procedure and risk assessment.

Compatibility / protection note: If you are selecting overboots for chemical splash or cytotoxic handling, review the manufacturer documentation and align to your hazard assessment and task exposure (chemical and time dependent).

BDOB-L (Non-Sterile) Class 10 / ISO 4 500 mm Longer Length CleanTough™ (Low Lint) Top & Ankle Ties 150/Case

Ansell BioClean-D™ BDOB-L Longer Length Overboots — footwear control to reduce contamination transfer

Ansell BDOB-L BioClean-D Longer Length Overboots

SKU shown: BDOB-L (non-sterile longer length overboots, 500 mm).

Why footwear control matters in ISO-classified cleanrooms

Floors and footwear are persistent contamination sources. Overboots are used to reduce that transfer by placing a controlled, low-shedding barrier between the wearer's shoes and the cleanroom floor. BDOB-L is positioned by the manufacturer for controlled and critical environments where low lint, stable fit, and consistent donning help protect product and process integrity.

What this product is used for

Footwear barrier control when entering and working in ISO-classified cleanrooms and clean zones.
Low-lint garmenting programs for pharma/biotech, medical device, lab, and manufacturing clean areas.
Lower-leg interface coverage where standard shoe covers do not provide enough height or stability.
Workflows where top-and-ankle tie control reduces slippage and "pumping" during walking.

Why customers consider BDOB-L

Longer coverage: 500 mm height helps reduce exposed lower-leg interface risk.
Low shedding basis: manufacturer publishes Helmke Drum particle shedding results.
Fit stability: tie-fastenings at top and ankle help prevent slippage.
Slip-resistant sole: supports safer movement in controlled areas.
Documentation support: PDS / DoC / IFU and material TDS available for qualification review.

Materials, composition, and build

BDOB-L is constructed from CleanTough™ material, described as a polyethylene / polypropylene laminate. The overboots are antistatic / static dissipative and low-linting, with bound seams and single needle stitching.

Functional design features include a slip-resistant sole and tie-fastenings at the top and ankle to maintain coverage and reduce movement-driven contamination release during walking and direction changes.

Packaging, traceability, and compliance

BDOB-L is packaged as 30 pieces per sealed inner PE bag; one inner per sealed outer PE bag; five outer bags per lined carton (150 pieces). Shelf life is five (5) years from date of manufacture.

Compliance documentation is available via the linked Declaration of Conformity and IFU. Treat these as inputs to your facility's qualification package along with your gowning SOP, training, and monitoring program.

Gowning (donning) education — ISO first, then EU Annex 1

ISO approach: build footwear control into an Operations Control Programme

Prepare the boundary: stage BDOB-L on the clean side; avoid bringing opened packs back into the "dirty" side.
Don without floor contact mistakes: sit or use a step-over bench so shoes do not cross the boundary unprotected.
Control touch points: handle inside surfaces; avoid touching the sole and lower outer surfaces with bare hands.
Bring to full height: pull the overboot up to maximize 500 mm coverage; ensure it sits smoothly with no folds that drag.
Tie top and ankle intentionally: secure ankle first (stability), then top tie (coverage).
Verify the interface: confirm your coverall/boot interface follows your SOP and taping rules if used/validated.

EU GMP Annex 1: sterile-area expectations may require sterile footwear

Because BDOB-L is non-sterile, many Annex 1-driven aseptic workflows choose sterile overboots (e.g., S-BDOB-L) or an approved sterile footwear approach aligned to their contamination control strategy.

Key takeaway: the garment only performs as well as the donning discipline behind it. Overboots reduce transfer risk when the boundary is respected, ties are secured consistently, and removal is controlled to avoid re-aerosolizing contamination.

Common failure modes

Boundary crossing without protection: use a step-over bench and don on the clean side.
Loose ankle fit (slippage): tie the ankle intentionally; re-check after initial walking.
Dragging folds: pull to full height and smooth the material to avoid floor contact.
Touching the sole: treat the sole as "dirty" even in clean areas; avoid hand contact.
Fast doffing that aerosolizes particles: remove slowly; turn inside out to trap contamination.

Closest alternatives

Sterile variant: Ansell S-BDOB-L (when sterile footwear is required).
Integrated boot option: consider coveralls with integrated boots when you need fewer interfaces to manage.
Other sterile footwear programs: compare sterile packaging, sterility method, and certificate availability against your audit and aseptic requirements.

Critical environment fit

BDOB-L is typically selected for ISO-classified cleanrooms where footwear control is required and non-sterile garments are acceptable. If your process is Annex 1–driven for aseptic manufacture, confirm whether sterile footwear is required and select accordingly.

SOSCleanroom note about SOPs

The Technical Vault is written to help customers make informed contamination-control decisions and improve day-to-day gowning technique. It is not your facility's SOP, batch record, or validation protocol.

If you adapt any technique guidance from this entry, treat it as a starting template. Review and approve the final method internally, then qualify it for your surfaces, footwear types, room grades, and monitoring program.
