Safety Violation at wbgeneral

Labmembers --

My apologies for the general broadcast, but the feeling is that the 
perpetrator just simply cannot be a qualified user at wbgeneral, given 
the violations (and therefore might not be on the wbgeneral email list.) 

 From the evidence this morning, it would appear that someone used 
wbgeneral without enabling it and leaving what appears to be ammonium 
fluoride/BOE crystals in the main sink as well as in spots on the 
bench.  There also appear to be bits of broken glass wafer and tiny 
flecks of metal everywhere (there are even metal flakes on the N2 gun!)  
Clearly, no one trained by Uli would have done this (though, as she has 
pointed out, I covered wbgeneral training in her absence, so can't 
attest for my trainees.)

And if anyone has observed someone using wbgeneral between about 5 pm 
yesterday and 9 am this morning, please be a good community member and 
share what you know with your favorite/most-trusted SNF staff member.

Thanks for your attention --
