These values will produce EO and Ethylene Chlorohydrin residual levels in the
transceiver and patient cable plastic that meet ISO 10993-7 in conjunction with
AAMI Technical Information Report 19, that the FDA currently endorses.
References OSHA: Standard for acceptable levels of personnel exposure to Ethylene Oxide
Gas: 1 ppm on an eight-hour time-weighted average basis.
Reference: U.S.A. Federal Regulations 49 FR 25734/29 CFR Part 1910.1047,
June 22, 1984; final approval 50 FR 9800/2- CFR Part 1910.1047, March 12,

Step Action
1 To dissipate residual EO, aerate the processed equipment with air
that has been bacterially filtered, using a mechanical aerator or
combination sterilizer/aerator as follows:
1
Time: 8-9 hours
Temperature: 54.4 +/- 2.8
