The American Glovebox Society (AGS) was created in 1986 for the purpose
of advancing the science of glovebox and containment technology. This
mission still drives the Society today. One method for fulfilling this mission is
through the AGS Conference which provides a forum for industry experts (and
those new to the industry) to share ideas, present lessons learned, and discuss
issues. The Conference provides vendors an opportunity to demonstrate their
products and/or services and allows operators to share their experiences
through technical presentations and displays.
While the Conference provides a means for members to meet once a year
and share information, advancements in technology have provided another
method for conveying information through the use of social media. Social
media includes web- and mobile-based technologies which are used to turn
communication into interactive dialogue among organizations, communities,
and individuals. Social media has revolutionized how we communicate. No
longer do we have to wait until the next AGS Conference to communicate.
Interactions with members and dissemination of information can now be
instantaneous.
As the incoming AGS President, one of my goals is to expand AGS’s
involvement in social media. To accomplish this, AGS has created LinkedIn,
Facebook, and Twitter accounts. I am requesting that you connect to us, like
us, and/or follow us, as applicable, on your computer or mobile device. I would
appreciate if you spread this message within your organization, as well. I
encourage those who do not consider themselves internet savvy to give it a try.
The interfaces are fairly simple, and I believe it will be worth your while.
Connecting with AGS on these sites will allow you to network within the
industry, pass on any glovebox-related news, or ask questions of your
colleagues, all in an instantaneous manner.
AGS will be providing information on the Society, industry updates, and
fun glovebox stuff, as well. We are also relying on our membership for content.
Once we are connected, you can help generate our content by sending us
glovebox-related news or information via any of the three sites or by email for
us to post. Please contact the AGS office with any questions.
Going forward, I believe social media will be the primary method for
communication throughout all industries, and it is time for the AGS to
embrace it.
Thank you for your participation in the society!
Sincerely,
Nate Levene, AGS President

AGS Conference
The 2012 AGS Glovebox/Isolator Conference andTrade Show was a resounding success! Held
August 6th – 8th in Arlington, VA, the Conferenceprovided an opportunity for attendees to meet andcollaborate on matters affecting the containmentindustry.
The Conference kicked-off with a keynote addressprovided by Dr. John E. Kelly, Deputy AssistantSecretary for Nuclear Reactor Technologies, U.S.Department of Energy. The keynote provided a greatstart to the Conference which focused on best practices.Experts from the pharmaceutical, biocontainment,nuclear, and radiological industries provided insightand training on best practices that affect the day-to-dayoperations of the containment industry. Specifically,“benchmarking” in the areas such as glovebox design,fire protection, fabrication techniques, training, andergonomics were discussed.
During the interactive case study, attendees wereassigned to teams and given a hypothetical problem tosolve, thus providing attendees the opportunity toapply the knowledge and training they receivedthroughout the Conference. Teams developed theirsolutions and then, presented to the entire group and toa panel of judges. This was a fun, interactive exercisethat provided not only education but also the benefit offorging a relationship with other attendees with similarjob characteristics. The networking resource thisprovides is invaluable and one of the great benefits ofthe AGS Conference.
One of the highlights of the Conference was thedemonstration provided by technicians from LosAlamos National Laboratory (LANL). LANL techni-cians provided live demonstrations of glovebox transferport operations, bag-in and bag-out techniques, glovechange-out and a HEPA filter change-out. At thecompletion of the demonstrations, a hands-on-trainingsession was held, allowing attendees to performglovebox activities under qualified supervision.
Beyond providing high quality education andtraining, attending the AGS Conference offersattendees the opportunity to interface with gloveboxusers, fabricators and the ability to meet with vendorsto learn about new containment technology.
Plans for next year’s Conference are underwayand it promises to exceed expectations. The Call forPapers is now posted on the AGS website and we inviteyou to submit your technical paper or poster forconsideration for next year’s Conference program.Mark your calendar and make plans to join us July 29-31, 2013 in beautiful Lake Tahoe, Nevada! �

ABSTRACTHere at Los Alamos National Laboratory (LANL), the
Department of Energy (DOE), and Los Alamos NationalSecurity (LANS), is challenging LANL employees to domore with less. In the case of the recently constructedRadiological Laboratory/Utility/Office Building (RLUOB)the staff here has risen to the challenge by designing andconstructing a multi-purpose building with the intent ofachieving LEED Gold certification through the UnitedStates Green Building Council (USGBC). With nearly20,000 square feet of radiological space, a trainingcenter, utility building, and office space to support 350personnel, this effort is complex requiring innovation tosucceed.
The radiological laboratories contained in RLUOBrequire gloveboxes that are not only safe, but ergonom-ic, efficient, and comfortable to the users for researchexperiments. In order to meet rigorous glovebox usagedemands, high performance lighting systems must bespecified. A study was performed to reevaluate theincumbent florescent lighting systems with the objectiveof selecting an advanced LED system which was morecompact, energy efficient, cost effective, and easy to
install. This article will outline the study performed atLANL to select the high performance fixtures currentlyemployed on all gloveboxes within the RLUOB facility.
This article will touch on the following topicsconcerning using LED lighting in glovebox applications:
• Current mixed waste issues
• LED technology
• RLUOB lighting selection process
• Luminaire testing
• User ergonmonics
• Installation methods
INTRODUCTION – Mixed up WasteIn recent years increased demand for energy efficient
lighting, waste reduction initiatives, and advancements inmaterial science have made LED lighting undergo a stepchange in luminous efficacy (lumens generated per Wattof energy consumed). Figure 1 illustrates the dramatic rateat which LED efficacy has improved in recent years.

This advancement in technology has made solid-stateLED lighting a viable alternative to florescent lights in avariety of applications. Although this technology is nowprevalent in outdoor lighting and retrofit applications, acomprehensive study has not been performed for its usein radiological areas. The most recent revision to theLANL Engineering Standards Manual Chapter 7 D5020“lighting and branch circuit wiring” now requires LEDlighting in radiological areas. The motivation behind this isnot due to energy efficiency alone, but mainly due to theexpensive mixed waste issues surrounding the disposalof contaminated bulbs that also contain toxic mercury(Hg) residue (hazardous waste). Even with the latest bulbpulverizing technology, this waste remains a significantdisposal cost to the national lab. Figure 2 illustratescurrent costs to dispose of different types of waste.
Figure 2: Costs of disposal of various types of waste at LosAlamos National Laboratory.
One can see that the costs to dispose of mixed lowlevel waste increases dramatically over the cost torecycle lamps classified as Haz/Chem waste. This is themain driver to eliminate lighting, using mercury contain-ing lamps in radiological environments. Radiologicalareas that contain disposable florescent bulbs mustreplace these bulbs (known as relamping) after approxi-mately 15,000 hours of use (every 5 years), while goodLED replacement luminaires are rated at 50,000+ hours(15+ years), eliminating 3-4 bulb changes from the wastestream. It should be noted that the fixtures chosen in thisstudy ended up costing less per glovebox (initial cost)than their florescent equivalents.
SELECTION PROCEDURE – Stage 1In order to light the gloveboxes with enough lumens
to approach the AGS recommended 100 footcandles atthe working surface, a fairly dense high output light isnecessary. The challenge for the CMRR engineering teamwas to come up with an alternative to the high outputflorescent filming luminaire, formally used that would stillfit in a fixed 23” x 6.5” light window.
Figure 3: Florescent lights formally used for glovebox lighting
STICK TO THE “TASK” LIGHTINGEVALUATION
The team paged throughnumerous catalogs, websites, andworked with resellers to come up witha initial pool of potential candidatesfor the first stage of evaluation. Theteams considered everything fromLED kitchen counter lights, jewelrydisplay systems, to reef capable fishtank lights and everything in between.It quickly became apparent that lightswith the appropriate lighting powerdensity required for the gloveboxeswere mostly task lighting luminaires,and not fixtures built for generalbuilding lighting. The luminairespicked for the first stage of theselection process needed to fit two

main criteria: fit in the light window and provide minimumof roughly 3000 lumens. Approximately 10 fixtures werechosen to move into the next phase of evaluation.
SELECTION PROCEDURE – Stage 2The most promising candidates were assembled in a
spreadsheet to compare them, based on various projectrequirements. The following criteria were evaluated:
• Power Consumption (Watts)• Lumens (lm)• Color Temp (Kelvin)• Color Rendering (CRI)• Beam Angle (Deg)• Dimming (Y/N)• Integrated Controller (Y/N)• Integrated Switch (Y/N)• Cord and plug (Y/N)• Estimated Price per window ($)• Installation Complexity
Realizing that no one candidate in considerationwould have every desired feature, rows were added todescribe advantages and disadvantages and weightingwould be given to features most important to the projectand the users.
Figure 4 (below) illustrates the candidates evaluated inStage 2:
Figure 4: Illustrations of the lights chosen for a technicalevaluation of their performance specifications.
Once the evaluation was complete in spreadsheetform, the most promising candidates were selected to beevaluated in the next phase of the test. It is important tonote that certain candidates such as the Cree LR6 andPhillips iW Blast were eliminated based on installationrequirements and not light quality. In our case it wasimportant to choose equipment that could be easilyretrofitted to fit the glovebox windows and mountingstuds without modification to the glovebox designsthemselves.
LUMINAIRE TESTING – Stage 3Samples were obtained from local suppliers to be
installed and evaluated on the glovebox windows. Themodels evaluated in the lab were Numbers 2, 3, 4, 5, 8,9, and one additional light that had already been in use asan LED alternative in another facility.
For the Stage 3 evaluation a typical glovebox waschosen and 6 marks were made on the working surfaceto ensure foot-candle measurements were taken atconsistent locations. Measurements were taken neareach corner and two on the center working surface (onenear the front and the other near the rear). This ensuredthat data would reflect the evenness of the light levelsthroughout the cavity. Measurements were taken, using acalibrated digital light meter, after sufficient warm up timewas given to each fixture.

User Ergonomics:Representatives from the user groups were invited to
make subjective comments on the light quality to ensureergonomic and human factors were addressed in theevaluation. Color wheels and charts were used in thegloveboxes to evaluate color rendering (CRI) and readingcomfort. Because LED light sources are usually an array ofdiscrete light sources focused by individual lenses, usersalso experimented with their hands in the boxes to ensureshadowing and glare were not issues.
Results: The two front runners in the testing were quickly identi-
fied as being the Moda Light Kandi Stix and the WaldmannMach LED Pro. The Moda Lights were eliminated due tomore complex mounting requirements (four daisy chained“sticks” were required per light window) although theirability to accept line voltage (120v) without aconverter/driver would have proved to be a benefit duringinstallation. The Marineland Reef Capable consumer gradefish tank light was actually very promising. It had durableconstruction, a slim form factor, built-in power switch andstand, and it accepted line voltage for a price that was verycompetitive. It was eliminated because of its color tempera-ture which was over 10k with integrated actinic blue LEDs,which caused eye strain and affected color rendering for theusers. It should be noted that if the manufacturer was willingto modify their design for a project with more lead time,these fixtures could prove to be a very practical solution.
The Waldmann Mach LED Pro was chosenfor many reasons:
• Only two lights per box met footcandle requirements• Durable monolithic aluminum construction and
form factor allow for simple mounting bracket fabrication.
• Durable glass lenses won’t degrade like plastic might in presence of radiation sources.
• Low profile opens space above glovebox for maintenance access.
• Switchable cord and plug power supplies were supposed to make installation a breeze (See lessons learned.)

Installation
Mounting:A stainless steel I shaped bracket was fabricated to
mount the waldmann fixtures side-by-side above the lightwindow. The bracket shown here was bolted to theexisting studs on either side of the window, suspendingthe fixtures directly above it.
Figure 7: Waldmann Mach LED Pro fixtures mounted toglovebox with custom stainless bracket in-between.
LED drivers and installation considerations:The default drivers for the Mach LED Pro fixtures are
Sylvania Optotronic OT20W Modules, which convert 120vline voltage down to 24v DC to drive each 18wattluminaire. The problem with this design is that they aredesigned to be DIN rail-mounted and require a UL-listedenclosure when installed. This results in increased instal-lation costs and additional physical space. In order tosimplify installation, the project chose to specify theSylvania Optotronic OT30/120/24CORD 30watt driversinstead. The OT30 Cord models were UL-listed as a unitthat included a switch, cord, and plug. This enabled theinstaller to simply plug them in on both sides and securethem with zipties. It’s worth noting that matching femaleconnectors did have to be purchased and installed on the24v luminaire side which didn’t present a problem.

Figure 8B: Silvania Optotronic OT75W hard wired powersupplies being installed in an electrical enclosure.
Driver supply issues:Unfortunately no installation project goes without hiccups. Midway through
the installation it turned out that the OT30 cord and plug model drivers werediscontinued and supplies exhausted so the project was forced to substitutean alternative. The model recommended was the OT75W which was able todrive multiple lights reducing the quantities procured but cost more to installdue to the enclosure mounting requirements since it is delivered with wireconnectors on both the 120v and 24v sides.
Lessons learned: If you are looking to go with LED luminaires on your gloveboxes, pay
attention to ease of installation to reduce total installed costs. Here are somerecommendations:
Pay close attention to life ratings: If the LED fixtures are rated less then50,000 hours don’t buy them. Some manufactures over-drive their products toincrease light output per diode thus reducing the lifespan of the product.
In some cases it is worth procuring luminaires with built-in drivers thataccept line voltage. This relieves the burden of procuring and mating up thelight and driver during installation.
In cases where a separate driver is used, pay close attention to instal-lation methods to ensure that excessive cost is not incurred during theinstallation phase.
Analyze wide, unpartitioned, gloveboxes separately from partitioned ones.On gloveboxes with multiple light windows and no partitions, there will likelybe “spillover” from adjacent lights increasing levels beyond required levels.View this as an opportunity to save money by using less fixtures in the centerposition to achieve appropriate light levels.
Conclusion:Using LED luminaires in gloveboxes can be an efficient, cost-effective,
space-saving solution which addresses many disposal issues that occur withmore common florescent solutions. That being said, it is important to properlyspecify and test lighting with programmatic users present prior to purchasingto ensure that correct light levels and color temperatures are chosen toincrease comfort and reduce eye strain of glovebox users.

For longer then I care to admit, the AGS SDC has been working
on the Standard of Practice for Leak Test Methodologies for
Gloveboxes and Other Enclosures. Well, it is finally complete!
The writing is done, subcommittee reviews finished, and the full
Standards Development Committee review was completed at our
Spring meeting in Indianapolis. The document is now in final
formatting and will then move to publishing. We know there are
readers out there anxious for the document; watch your email for
the release announcement. Information will also be posted on the
AGS website and social media sites as soon as the document is
available for ordering.
To streamline document development, the SDC is trying
something new; we are splitting the Standard of Practice for
Glovebox Ancillary Equipment, led by Med Allen of SRNL, into
concentrated sections. As each section is completed, they will be
immediately published, allowing the committee to issue and
disseminate documents more efficiently. The first section to be
published will be the Standard of Practice for Glovebox Inert Gas
Recirculating Purification Systems (SoP IGRPS or I-GRPS for
you acronym savvy, pronounced I-gripps), led by Will Mathews of
Vacuum Atmospheres. The group has made significant progress
on the Standard and we anticipate the release of I-GRPS next year.
At the AGS Conference in Washington DC, the SDC did
some strategic planning. Most of the discussion centered on
bringing previously published documents up-to-date. An up-to-
date document, as defined by ANSI, is a document which has been
reviewed in the last five years. Patrick Westover of SRNL will be
leading the effort to update the Guideline for Gloveboxes, AGS-
G001. During the process of updating an AGS Standard, the SDC
will be doing three things: 1) adding new sections due to updated
technology, 2) updating with new information and references
included in new AGS SDC publications, and 3) reviewing
comment forms. The comment forms are in the front of each AGS
document, and are available on the AGS website, www.glovebox-
society.org. Should you have any comments regarding the
Guideline for Gloveboxes, AGS-G001, please submit your form to
the Society office as soon as possible.
In conclusion, I want to recognize the hard work done by this
committee. It is amazing the amount of time spent authoring,
reviewing, and editing documents. All done by members who
volunteer their time and expertise to provide valuable information
to the containment industry. I want to thank everyone who is
actively participating or who has participated in the past. Your
commitment has made a difference and continues to enable AGS
to fulfill its mission of disseminating information to the contain-
ment industry. �
