12-24 hours
What should be done to sharp ends of surgical implements prior to sterilization?
They should be covered and wrapped in a water resistant shroud
How long is the recommended storage time for autoclaved items?
1 year
What is the purpose of labeling and dating sterile supplies?
To ensure traceability and expiration dates
What is the purpose of TST strips in the sterilization process?
To monitor time, steam, and temperature
