Metal hydride materials of a composition which is not well characterized should be handled with procedures that assume a "worst case" for that class of materials, intermediates or precursors.
Laboratory procedures should be in…
1. Evaluate any change in normal procedures or conditions for storage of aluminum hydride products. In this case, the aluminum hydride material was typically stored at -35°C in the glove box freezer. However, due to a change in glove boxes, this…
1. All samples with potential for hydrogen buildup should be limited to ground shipment only. (This shipment was by ground and air. If this incident were to have happened in an airplane, the consequences may have been worse.)

Now, when conducting a sulfur deprivation test, vessels are ventilated to prevent over pressurization and safely facilitate the release of excess hydrogen.
- Metal hydride materials of a composition which is not well characterized should be handled with procedures that assume a "worst case" for that class of materials, intermediates or precursors.
- Laboratory procedures should be in…
Laboratory accidents can happen despite the best preparation and careful attention to procedures. However, the lesson to be learned here is that employees must always be sure they understand the hazards of the activities, and that they know how…
On-site personnel performing treatment of reactive metals/chemicals must continue to exercise caution. Although there is an inherent risk in treating reactive metals/chemicals, personnel must adhere to conduct of operations principles to include…
In the future, the laboratory will issue a memorandum about this incident to illustrate the need to wear safety glasses with side shields, store chemicals compatibly, take care when placing chemicals in the refrigerators for storage, and keep the…

The researcher's failure to pull the fire alarm was an oversight of required facility practice. The alarm should have been triggered in consideration of the potential for greater harm to personnel and facilities.
Hot, reacting ammonia…
