 From personal experiences with handling pyrophoric reagents (such as  
LAH, n-BuLi, t-BuLi, Mg, etc.)

When performing on-scale reactions involving reagents such as these,  
I would always perform the operation with, a) by DOUBLE TIPPED  
cannulas, and b) under Argon atmosphere. Additionally another staff  
member should be present during such an operation and notifications  
should be posted accordingly.

Syringes should NEVER be used when handling these reagents!

I believe Aldrich may have some Technical Bulletins on this subject...?

Note that when Ar was not available, N2 would be used, but keep in  
mind that N2 atmospheres can cause ignitions.

Seems as if She was going to Law School...Hmm I wonder why? Sad
indeed. But that is due to a simple lack of training.

Just because you're a grad. student doesn't mean You know everything
& can't ask questions. Such as the case with TMSCN....

This debate can go on & on & on, but suffice it say that when in  
doubt ask questions.

The only dumb (and possibly fatal) question is the one You don't ask.
