EO Gas Cartridges should be aerated for a minimum of two (2) hours before
disposal. The empty cartridge can aerate while located inside the GS Series sterilizer chamber
cartridge holder during a normal aeration cycle. After aeration is complete, remove the cartridge
from the holder and dispose of it in non-incinerated waste or recycle per your facility’s requirement.
See ANNEX E for additional information related to the proper handling of ethylene oxide (EO).
Outside Discharge
The ventilation system should exhaust to the outside. Use a roof-top discharge. The discharge point
should be at least 7.6 m (25 ft) away from any possible sources of ignition, openings to building, or
pedestrian traffic ways. Greater distances may be needed in some locations. Use one of the types
of discharge terminations illustrated in Figure 17.
It may be helpful to work with an industrial ventilation consultant or ventilation contractor to help
design and install the local exhaust system.
