empty bottles in the pass through

[Linda Whittelsey]

Empty bottles should only be put back into the pass through from which they 
originated.  I found two 50:1 HF bottles and a Hydrogen peroxide bottle in the 
left pass through.  This is not where they came from. The chemicals are 
separated due to chemical compatability issues.  Even an "empty" bottle poses an 
incompatability threat, as there is always some residual chemical in the empty 
bottles.  Please put empties only in the pass through where you got them before 
they were empty.  Thanks
