“…The use of Cause and Effect Diagrams in the analysis of glove breaches and failures, air-purifying respirator incidents, have been previously reported in this journal. 3,4,8 The Cause-Effect Diagram was used in this analysis because it is a good tool for examining condition-related problems, as shown in Figure 5. Not using a drum lifter was the active error that triggered the immediate, undesired consequences: dropped drum, as shown in Table 2.…”

“…The worker-involved meeting to discuss the incident, called the ''fact finding'' meeting, is the most immediate part of the incident investigation and plays a central role in launching an effective partnership between workers, supervisors, and managers to understand the incident and improve future performance. 3,4 The most important outcome of the ''fact finding'' meeting is the establishment of a timeline. Established criteria determine reporting requirements.…”

A traditional view of incidents is that they are caused by shortcomings in human competence, attention, or attitude. It may be under the label of ''loss of situational awareness, '' procedure ''violation,'' or ''poor'' management. A different view is that human error is not the cause of failure, but a symptom of failuretrouble deeper inside the system. In this perspective, human error is not the conclusion, but rather the starting point of investigations. During an investigation, three types of information are gathered: physical, documentary, and human (recall/experience). Through the causal analysis process, apparent cause or apparent causes are identified as the most probable cause or causes of an incident or condition that management has the control to fix and for which effective recommendations for corrective actions can be generated. A causal analysis identifies relevant human performance factors. In the following presentation, the anatomy of a radiological incident is discussed, and one case study is presented. The contributing factors that caused a radiological incident are analyzed. Underlying conditions, decisions, actions, and inactions that contribute to the incident are identified. This includes weaknesses that may warrant improvements that tolerate error. Measures that reduce consequences or likelihood of recurrence are discussed.

Self-contained fire extinguishers are a robust, reliable and minimally invasive means of fire suppression for gloveboxes. Plutonium gloveboxes are known to present harsh environmental conditions for polymer materials; these include radiation damage and chemical exposure, both of which tend to degrade the lifetime of engineered polymer components. The primary component of interest in self-contained fire extinguishers is the nylon 6-6 machined tube that comprises the main body of the system. Thermo-mechanical modeling and characterization of nylon 6-6 for use in plutonium glovebox applications has been carried out. Data has been generated regarding property degradation leading to poor, or reduced, engineering performance of nylon 6-6 components. In this study, nylon 6-6 tensile specimens conforming to the casing of self-contained fire extinguisher systems have been exposed to hydrochloric, nitric, and sulfuric acids. This information was used to predict the performance of a load bearing engineering component comprised of nylon 6-6 and designed to operate in a consistent manner over a specified time period. This study provides a fundamental understanding of the engineering performance of the

“…A glove box, also known as an anaerobic station, is a vacuum environment without any water (H 2 O), oxygen (O 2 ), and organic gas, where high purity inert gas is filled, and the active substances are filtered out, which can prevent the external personnel from direct contact, so that the materials placed in the glove box can be stored or tested in the vacuum environment free of water, gas, and oxygen, and the material is operated by people in a safe and contactless manner [1]. The glove box is used in a wide range of applications such as the scientific research of chemical/chemical engineering/material/drug, and so on; the research and manufacturing of organic optoelectronic OLED/polymer PLED light emitting displays; the manufacturing and research of lithium ion batteries/lithium polymer batteries/solar cells/high capacity capacitors; the research and manufacturing of special (HID) light bulbs; metal welding or laser metal welding process; the preservation or research and manufacturing of noble sensitive drugs and nuclear energy research; and so on [2][3][4].…”

This study proposed a high vacuum deoxygenated and water removal glove box control system. Through parameter setting, the system can automatically perform various glove box cleaning operations and quickly reach the micro-oxygen and microwater concentration requirements. In addition, two sets of reaction tanks are built in the system, and the hardware pipeline switching design and monitoring software control are used to provide two sets of reaction tanks to execute the cycling cleaning and cycling regeneration operation procedures synchronously, which can effectively solve the problem of interruption of the experimental process, improve the efficiency of its cleaning operations, and greatly reduce the manpower and material costs of the glove box operation. In addition, the system can automatically record the relevant data during various operations for the analysis of glove box monitoring effectiveness.
