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…
As stated on the MSDS and also on the container labels, LiAlH4 should be handled under argon. LiAlH4 is advertised and sold as a powder. If the researcher had to scrape it out of the jar, then it was no longer a powder, which seems indicative of…
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…

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…
