Warning
Do not overload the trays.
Overloading trays may result in
inadequate sterilization and
unsterile instruments.
Warning
Monitor the sterilization process with
process monitors and biological indi-
cators as described in
Recommended Monitoring (p. 33).
Preparation of Carbon Steel
Instruments
Carbon steel instruments must be carefully prepared prior to
sterilization to prevent rusting. After cleaning according to the
manufacturer's recommendations or the methods presented
in
Instrument Cleaning Prior To Sterilization
, prepare car-
bon steel instruments as follows:
1.
Prepare a 2% solution of sodium nitrate in water
(approximately one table spoon in a quart of
water). Completely immerse the instruments in the
solution and allow them to soak for three minutes.
2.
Remove the instruments and package them for
sterilization or place on trays if sterilizing
unwrapped.
Do not rinse or wipe instruments
prior to sterilization.

promotes drying.
