Micronova Cleanroom Barrier Tape - CAUTION or DANGER DO NOT ENTER - Non-Adhesive Polyethylene - 3" x 1,000 ft - 12 Rolls/Case
Micronova Cleanroom Barrier Tape is a high-visibility, non-adhesive polyethylene film designed for temporary restricted-area identification and access-control warnings in cleanrooms, laboratories, production facilities, and controlled environments. Available with either yellow CAUTION messaging or red DANGER DO NOT ENTER messaging, it helps personnel recognize areas where specific safety or entry restrictions apply.
The tape is manufactured from 3-mil polyethylene film with bold black lettering in English and Spanish. Each roll measures 3" wide x 1,000 feet long and is wound on a 3" plastic core. Its non-adhesive construction allows the material to be deployed as a visible boundary between appropriate supports without applying an adhesive layer to facility surfaces.
The BT200-3YE yellow version displays CAUTION / CUIDADO. The BT100-3RE red version displays DANGER DO NOT ENTER / PELIGRO NO ENTRAR. Both versions use black bilingual print and the same polyethylene film dimensions.
Micronova positions the product for use in ISO Classes 5 through 9 controlled environments. This is a manufacturer-intended application range, not a certification of a facility's cleanroom classification or proof that the tape satisfies a particular particle-release requirement.
The manufacturer supplies each roll individually bagged, with the part number and lot number identified on the packaging. Both CAUTION and DANGER configurations are offered by SOSCleanroom in cases of 12 rolls.
The barrier tape is not irradiated and not autoclavable. It should be used under the facility's approved contamination-control and safety procedures. Where an actual physical barricade, locked entry point, engineered containment system, or equipment isolation is required, warning film alone is insufficient.
Restricted-Area Identification Advantage: Micronova BTx00 barrier tape provides bilingual warning messages, two clearly differentiated hazard-identification options, and 1,000 feet of non-adhesive film per roll. It supports quick, visible temporary boundaries while allowing the facility to maintain separate procedures for actual access control and hazard protection.

| Typical Role |
Visible caution messaging where the site has identified a condition requiring warning |
Explicit restricted-entry messaging where the site has determined that personnel must not enter |
Yellow and red barrier tape should not be treated as automatic substitutes for the facility's formal hazard assessment, approved signage, permit controls, access authorization, or mandatory physical barriers.
Warning Selection Guidance: Yellow CAUTION communicates a warning; red DANGER DO NOT ENTER communicates an explicit no-entry message. Define when each is used in the facility's approved safety procedure rather than relying on color alone.
Non-Adhesive Polyethylene Film Construction:
Micronova BTx00 barrier tape is made from non-adhesive polyethylene film. The 3-mil film is supplied with printed warning text and wound on a plastic core for dispensing during temporary boundary setup.
- Polyethylene Film: Provides the flexible backing material for suspended visual barriers.
- Non-Adhesive Design: Contains no pressure-sensitive adhesive for bonding directly to a surface.
- 3-Mil Thickness: Manufacturer-specified nominal film thickness.
- Black Printed Text: Provides the bilingual caution or restricted-entry warning.
- Plastic Core: Supports handling and dispensing of the long film roll.
- Surface Contact: Attach to suitable supports rather than expecting the film to stick to surfaces.
- Chemical Compatibility: Evaluate the actual cleaning solution and environmental exposure before use.
- Film Damage: Sharp fixtures, tension, traffic, and rough handling may tear or displace a temporary barrier.
- Particle Control: No numerical product-specific film-shedding or particle-release limit has been established from the identified manufacturer specification.
- Sterile Applications: The product is not irradiated or documented as sterile.
Adhesive Distinction: BTx00 is not an adhesive tape. It does not provide adhesive bonding, floor marking, surface sealing, or a manufacturer-defined peel strength. Any ties, clips, posts, or other installation accessories must be selected and qualified separately.
Visual Barrier vs. Physical Access Protection:
Barrier tape is designed to be seen and interpreted as a warning. It is not intended to stop a moving person, prevent a fall, contain a chemical release, or replace engineered protection from a hazardous operation.
| Barrier Tape Can Support |
Barrier Tape Does Not Replace |
| Temporary warning boundaries |
Engineered physical guarding |
| Caution and no-entry messaging |
Access locks or controlled entry systems |
| Temporary identification of maintenance areas |
Lockout/tagout or energy isolation procedures |
| Visual perimeter identification |
Spill containment or exposure controls |
| Visitor and contractor reminders |
Required supervision, permits, or site authorization |
Important Safety Limitation: Where the hazard requires prevention of physical entry, isolation from moving equipment, fall protection, or chemical containment, use the appropriate engineered and administrative controls. Warning film alone does not provide those protections.
Cleanroom Compatibility and ISO Application Range:
Micronova identifies its barrier film as intended for ISO Classes 5-9. Because it is a temporary facility-support product, the actual installation method and handling procedure may be just as important as the film construction itself.
- Manufacturer Positioning: Intended use in ISO Classes 5-9 controlled environments.
- Cleanroom Classification: The product does not determine or certify the room's classification.
- Material Introduction: Follow approved procedures for introducing individually bagged rolls.
- Handling: Avoid dragging film across dirty surfaces or allowing it to contact critical equipment.
- Particle Release: Evaluate handling and tearing where particulate sensitivity is important.
- Chemical Exposure: Confirm compatibility with actual cleaning and disinfection chemicals.
- Critical Product Contact: No direct product-contact qualification established.
- ESD Protected Areas: The film does not provide personnel grounding or static-dissipative performance.
- Sterility: Not irradiated and not supplied with a validated sterile claim.
- Autoclave: Not autoclavable.
- Site Qualification: Apply the facility's actual contamination-control and safety acceptance criteria.
ISO Guidance: ISO 5-9 is the manufacturer's application positioning, not an independently validated numerical cleanliness rating for every use condition. Qualify handling, installation, removal, particle contribution, and site safety requirements where necessary.
Recommended Temporary Barrier Setup Procedure:
The following general practices support consistent boundary identification. They should be adapted to the facility's approved EHS, maintenance, and contamination-control procedures.
- Identify the Hazard: Determine the restricted area and the required protective measures.
- Choose the Warning: Select yellow CAUTION or red DANGER DO NOT ENTER according to the approved site procedure.
- Verify the Manufacturer SKU: Confirm BT200-3YE or BT100-3RE.
- Inspect the Roll: Check packaging condition, part number, lot, film and printed message.
- Prepare the Work Area: Complete required hazard controls before installing a visual warning boundary.
- Select Safe Supports: Use appropriate posts, rails, or other approved fixtures.
- Position the Barrier: Establish a visible perimeter outside the hazardous activity.
- Keep Print Readable: Orient the warning text so personnel approaching the area can see it.
- Secure the Ends: Use approved knots, clips, or attachment methods that will not create additional hazards.
- Check Access Points: Ensure doors, walkways and alternate approach paths have appropriate warnings or access controls.
- Avoid Trip and Entanglement Hazards: Do not place unsupported film where it can snag equipment or personnel.
- Inspect Periodically: Check for torn, displaced, obscured or damaged barrier sections.
- Maintain Actual Protection: Continue required guarding, supervision, permits and isolation procedures.
- Remove When Authorized: Only remove the boundary after the responsible personnel confirm that the restricted condition has ended.
- Dispose Appropriately: Follow facility procedures for used or contaminated film.
Deployment Guidance: Use BTx00 to communicate and reinforce a boundary, not as the sole method of making an unsafe area safe. The responsible site team must select the actual access restrictions and protective systems for the hazard involved.
Chemical Compatibility, Handling and Service Limitations:
Micronova describes good general chemical compatibility with common solutions. This is a qualitative manufacturer statement and does not establish universal resistance to every solvent, cleaning agent, oxidizer, temperature or exposure period.
- Alcohol and Cleaners: Evaluate the actual solvent concentration and exposure duration.
- Disinfectants: Confirm suitability where repeated cleaning or spray exposure may contact the film.
- Oxidizers: Avoid assuming resistance to aggressive chemicals without specific evidence.
- Sharp Surfaces: Protect film from burrs, corners and abrasive contact.
- Temperature: No exact-model continuous-service temperature rating is established in the identified manufacturer specification.
- Tension: Do not rely on the film as a structural restraint or load-bearing component.
- Moisture: Check fixture attachment and warning visibility in wet areas.
- Flame and Heat: No flame-resistance or high-temperature protection claim established.
- Repeated Use: Inspect film condition and follow the facility's reuse or replacement procedure.
- Contaminated Areas: Handle removed film according to the hazards present in the work area.
Barrier Film Compared with Adhesive Facility Tapes:
Barrier tape and adhesive support tape serve different purposes. BTx00 is a nonadhesive film for temporary visual boundaries, while adhesive tapes are intended to bond, seal, label or mark suitable surfaces.
