The Lancs and Palo Verde teams designed, fabricated and set up two piping mockups based on PVNGS’ actual facility layout. Maintenance scenarios were presented and worked through. Additionally, the two teams developed solutions to recent industry challenges in weld preparations of EPRI Level 3 Alpha components, designing a new containment targeting this area. The PVNGS team gained a renewed appreciation for the utility of glovebags in resolving challenging problems in contamination control.

“Kudos to the entire Lancs Team for their innovative approach, positive attitude and professional response to the needs of the Nuclear Industry.” ~ Scott Williams, RP Ops Section Leader, Palo Verde Nuclear Generating Station

Lancs and its BOP Filters subsidiary manufacture flexible HEPA grade filters for use in contamination and particulate control applications. The filters are custom designed, and can be produced in various sizes and shapes. These flat and flexible panel filters can be welded or heat sealed by Lancs into polyvinyl chloride (PVC), or polyurethane (PU) plastic film. Our filters have been used in waste volume reduction, personnel protection, hazardous particle containment, environment control for purity of pharmaceutical reactions, containment of explosive environments (such as hydrogen generation during chemical reactions) and over-pressure protection in containment barriers. Applications also exist in biohazards and medical waste disposal, asbestos removal, “clean room” ventilation and equipment protection from hazardous environments.

We produce two standard sizes of filters: 1.5″ and 3.5″ in diameter, but can manufacture them in different sizes if required. Our filters are made to be welded into bags, sleeves or other barrier materials. The filter media function is the same regardless of the barrier material used.

BOP Filter/Barriers LLC was formed in 1998 to develop and market the technology of US Patent Number 5,720,789*.  The technology was invented by Paul A. Pinson at the Idaho National Laboratory (“INL”) as a solution to a nuclear waste bag venting problem regarding the need to allow air and other gasses to vent from sealed waste bags while maintaining containment of the nuclear contamination.  The patent was assigned to the Idaho National Laboratory General Contractor at that time, and BOP Filter/Barriers LLC was formed to develop and commercialize the technology. Mr. Pinson, as BOP Filter/ Barriers LLC’s founder and technical lead worked closely with Lancs over the subsequent years, and in December 2011 Lancs acquired the business including its worldwide exclusive license for the patent from Battelle Energy Alliance, LLC, INL’s current general contractor. Mr. Pinson serves as an advisor to Lancs on matters related to filter products.

*“Method for Contamination Control and Barrier Apparatus with Filter for Containing Waste Materials that Include Dangerous Particulate Matter”

The most important factor to consider is preventing contamination of the glove wearer through the damaged glove and spread of contamination when replacing the glove. To accomplish this, replacement of the damaged glove should not be attempted alone by the worker whose glove is damaged. It is also critical to ensure the new glove is properly oriented when it is being installed. This step is the easiest to miss in methods where the glove is installed inside out, then inverted after installation. The method used may vary depending on factors such as level of contamination, severity of damage, injury to personnel, etc.

Three methods of replacing damaged gloves while working in containment follow:

1.) Pull the damaged glove hand up and out until the glove is in the sleeve. Carefully remove your hand from the glove, leaving the glove inside the sleeve. Remove the tape and/or rubber ring from the glove ring. Carefully roll the damaged glove cuff lip away from the sleeve to expose the center of the glove ring.

2.) Place the replacement glove cuff lip over the glove ring. Secure the glove in place with tape (or by reinstalling the rubber ring, if used.) Take care not to catch the damaged glove between the new glove and the glove ring when taping down the new glove.

3.) With the replacement gloves in place, and working through the replacement glove, cautiously roll or lift the damaged glove cuff lip over the end of the glove ring. Pull the damaged glove free and draw it into the glovebag for transfer sleeve removal.

See diagrams of the above methods here.

1. Install rubber gloves (size 10 or 11 gloves are suggested) at locations indicated on the installation sheet.
2. Ensure proper orientation for working position.
3. Check the glove for pinholes by trapping air in the glove and squeezing.
4. Insert the end of the sleeve through the ring glove and fold the end of the sleeve over to cover the glove ring.
5. Tape the sleeve into the groove of the glove ring securely.
6. Insert the glove into the sleeve in the appropriate working position and fold the cuff of the glove over into the center groove of the glove ring.
7. Place the rubber ring (optional) over glove and sleeve and into the groove in the glove ring.
8. Apply tape over rubber ring. In place of a rubber ring, you can use a hose clamp, bungee cord, cable tie or Tygon tubing.
9. Check that glove is sealed by trapping air in sleeve and glove and squeezing.
