Dexterity test data contribute to proper glovebox over-glove use
- Los Alamos National Laboratory
Programmatic operations at the Los Alamos National Laboratory Plutonium Facility (TA-55) involve working with various amounts of plutonium and other highly toxic, alpha-emitting materials. The spread of radiological contamination on surfaces, airborne contamination, and excursions of contaminants into the operator's breathing zone are prevented through the use of a variety of gloveboxes (the glovebox, coupled with an adequate negative pressure gradient, provides primary confinement). The glovebox gloves are the weakest part of this engineering control. The Glovebox Glove Integrity Program, which controls glovebox gloves from procurement to disposal at TA-55, manages this vulnerability. A key element of this program is to consider measures that lower the overall risk of glovebox operations. Proper selection of over-gloves is one of these measures. Line management owning glovebox processes have the responsibility to approve the appropriate personal protective equipment/glovebox glove/over-glove combination. As low as reasonably achievable (ALARA) considerations to prevent unplanned glovebox glove openings must be balanced with glove durability and worker dexterity, both of which affect the final overall risk to the worker. In this study, the causes of unplanned glovebox glove openings, the benefits of over-glove features, the effect of over-gloves on task performance using standard dexterity tests, the pollution prevention benefits, and the recommended over-gloves for a task are presented.
