We recently had Sigma Aldrich (along with Neal Langermann) give an
excellent lecture at UC Irvine on safe handling of pyrophorics.  Dr. Mark
Potyen ( Sigma)  recommended having a fire watch (two-man operation)
during transfer of pyrophoric agents  as well as the use of fire resistant
clothing and gloves,  We have provided nomex lab coats and gloves to our
researchers.  Sigma also provided information on transfer techniques.

 If you're interested, I would recommend that you contact Scott Batcheller
at Sigma Aldrich.  I believe they are developing a video presentation.
