Welch Allyn Fl-100 Intubating Fiberscope - User Manual - Manual (Page 25)

2. IMPORTANT: Prior to placing the FL-100 Intubating
Fiberscope in a gas sterilizer or aeration chamber:
a) The “Red” ETO Gas Sterilization Venting Cap
MUST be “ON” securely.
NOTE: This is opposite of the immersion instructions.
b) Temperature must not exceed 55°C (131°F).
c) Pressure must not exceed 24 PSI.
d) Humidity must not exceed 50%.
e) Sterilization procedure must not exceed
4 hours.
3. Following ETO Gas Sterilization, aeration time of 72 hours at room temperature is required.
4. Aeration Chamber: To shorten the aeration time to 12 hours, an aeration chamber may be used,
provided the temperature does not exceed 55°C (131°F).
CAUTION: Prior to placing these endoscopes in an aeration chamber, the “RED” ETO
Gas Sterilization Venting Cap MUST be “ON” securely.
B) COLD STERILIZATION
For those situations where Ethylene Oxide (ETO) Gas Sterilization capability is not available, Welch Allyn endo-
scopes have been designed to withstand immersion in Glutaraldehyde solution for a maximum of 10 hours to
achieve “Cold Sterilization”. Never fully immerse a Welch Allyn endoscope without first conducting “Leakage
Testing” (see page 27).
CAUTION: NEVER EXCEED 10 HOUR MAXIMUM IMMERSION.
After immersion, the instrument must be thoroughly rinsed to remove all residual Glutaraldehyde solution.
After being thoroughly rinsed, Welch Allyn endoscopes must be allowed to “breathe”, balancing internal and
external humidity, by attaching the “RED” ETO Venting Cap.
