When I came in today both sulfuric:peroxide baths were overfilled to the top and the
logsheet showed I was the last to change chemicals there a week ago. At that time I
changed the HCl:H2O2 and HF, and the sulfuric:H2O2 baths were both filled to normal
levels. Since I was unable to find staff members today, I dumped and refilled the 4:1
bath, the HCl:H2O2  and HF, but did not touch the 9:1 bath.
