At the last CAP inspection I went through about (2 1/2 years ago) the 
inspectors insisted that temperatures had to be checked daily (including 
weekends) on all critical equipment (refridgerators, freezers, tissue 
processors, cryostats, etc.). That meant we had to find someone in the 
clinical lab to check temps on weekends since we were not open on weekends. 
As far as flotation baths, and other equipment that was used only when doing 
work, they had to be checked each day they were used. I don't know if the 
same guidelines would apply to your type of lab.

We have an accreditation inspection coming up in the year 2000. We are
updating all procedures. For recording temperatures, what is the standard
as to frequency. My director thought for example, that for a drying oven
once a week should be acceptable. I realize that to CYA, it is probably
better to do it daily, but I would like other opinions. What about water
baths for floating sections, are temps recorded regularly? If anyone has
written guidelines that they are willing to share, it would be
