[LORRE-list] 4107 hoods B, C and G cleared to use

All, Ryleigh Turner (REM) checked our fume hoods today (Lab 4107): - hood G clear to regular use; - Hoods B and C have a new sign attached to them with instructions: "For horizontal use only. Vertical movement of the sash will no longer protect the user" -> That means: if you are preparing you experiment, it is okay to move the sash vertically, but every time when running the equipment/experiments, move the sash only horizontally, to guarantee the air flow needed - for your safety. Thank you, Fernanda
