In the future, this mesoporous carbon material and ammonia borane:mesoporous carbon material will be handled under anaerobic conditions (glove box) to prevent further incidents.
No Lessons Learned, Specific Suggestions for Avoidance, or Mitigation Steps Taken.
This occurrence underscores the importance of appropriate design, equipment selection, and design review; the potential drawbacks of sharing utilities with other facilities; and the need to simplify [in this case, glove box atmosphere…
This occurrence underscores the importance of completing a hazard analysis for each different process. Non-safety-related systems or equipment may be used for purposes other than their primary purpose so long as potential hazards are identified…
The risk of a serious fire occurring inside the chemistry laboratory hood from use of hydrogen gas and/or presence of a small quantity of hydrazine-hydrate was underestimated. Additional control measures were required to reduce the risk of fire…
All safety devices worked as designed thereby protecting the environment and laboratory personnel. Researchers involved in the experiment acted properly and with the parameters set forth in operational procedures.
Follow up: Stops have…
Whenever a new program or organization is created, management should ensure that program interfaces and new responsibilities are clearly defined. Effective program integration is necessary to ensure that all responsibilities and requirements are…
Procedures will be revised to include specific information about hydrogen sensors and alarm controls. Caution will be added about sparks and flames in the fuel cell operation area. Workers will be cautioned that shunt resistors may reach high…
Management should ensure that a complete and thorough review of the previous work activities identified in the work package is performed at the pre-job briefing for the planned work. Work activities should be discontinued if any confusion exists…
This occurrence demonstrated the use of data by engineering to evaluate equipment problems. As the data changed, highlighting a problem with one-half inch PVC ball valves, the facility redesigned the valve extension and valve handle to prevent…
This occurrence highlights the need for ensuring work is organized and planned in a manner that is practical and efficient. The primary lesson learned from this occurrence is that personnel must be cognizant of the impact of their actions on…
Facilities should review their process systems to determine if they have valves installed that may be subject to this hazard. If so, facilities should conduct a detailed hazard analysis to determine the risk of valve failure. Detailed internal…
Cause and effect can sometimes be predicted by observing abnormal behavior even when the behavior is within specifications. Operators log equipment data and inform shift management when specifications are exceeded or when unusual equipment…
In this case, failure to recognize a run of tubing still maintaining pressure could have been avoided if such information was provided in a safety briefing. Knowledge of any job is the utmost importance in promoting and maintaining a safe working…
This incident highlights the need to ensure that the performance of special procedures does not place facility equipment in a condition that could lead to entry into a LCO.
