5.11 Emergency Door
Opening Procedure
This procedure should only be used when pressure remains in the
sterilizer chamber, and the door cannot be opened normally
because the sterilizer has lost either electric or water utilities. This
emergency door opening procedure can be used to retrieve a load
in the chamber. The procedure requires pushing on the door cover
to compress the door seal into the groove, then operating the door
manually.
NOTE: Do not use this procedure when a LIQUID load is inside the
sterilizer chamber. The load may boil over due to the fast exhaust
process. Contact STERIS for assistance.
Procedure:
Refer to Figure 5-12 .
1. Remove lower front panel on sterilizer.
2. Open chamber emergency exhaust valve located at bottom of
unit behind lower front panel.
Do not open second valve at this
time.
3. Monitor chamber pressure gauge located on front left hand side
panel. Wait until gauge reads 0 psig pressure in sterilizer
chamber. Valve must remain open, even after chamber pressure
reaches 0 psig.
4. When pressure in sterilizer chamber reaches 0 psig, open
second emergency exhaust valve. This valve relieves door seal.
Wait approximately three minutes for door seal to exhaust. Valve
must remain open.
5. Using a towel or sterilizer loading mitt, push door in at each of
four corners. This compresses door seal into door seal groove
and allows door to be opened.
WARNING – BURN HAZARD:
After manual exhaust, steam
may remain inside the
chamber. Always wear
protective gloves, apron, and
a face shield when following
emergency procedure to
unload sterilizer. Stay as far
back from the chamber
opening as possible when
opening the door.
