[Histonet] Cryostat Decontamination

[Laurie Colbert]

According the the NCCLS Publication "Clinical Laboratory Safety; Approved Guidelines" dated Sept. 1996:

1)  "Cryostats should be decontaminated frequntly with 70% alcohol after removal off tissue debris." 

2)  "The cryostat should be defrosted and decontaminated with a tuberculocidal antiseptic at least once a week.  If a suspected tissue contains mycobacteria, immediate decontamination should be done with a tuberculocidal antiseptic."

Do you all follow both of these requirements?  I have always done #1 but not #2.
