Why Preconditioning and Degassing?

Challenges to traditional Degassing methods today
Product degassing (removal of EO from the process, product and product packaging) should be split into three distinct EO level categories:
Removal of EO to ensure the product load is below an explosive level (below LEL).
Removal of EO to ensure the product load does not release EO in working areas bringing levels above permissible personnel working levels.
Prior to use the actual product contains EO levels lower than permissible levels allowed for patient contact.
If we consider additional Degassing in a 3-stage Process it is important that Levels 1 & 2 are met* prior to removal from the Sterilisation Chamber and further degassing is performed in a cell and/or room to attain Level 3 levels.
Item 1: the Lower Explosion Limit (LEL) level is a physical EO level that remains the same but both the personnel working levels and patient contact levels are under scrutiny and are destined to be reduced. These changes are a continuous challenge to traditional atmospheric degassing cell and rooms.
These changes are a continuous challenge to traditional atmospheric degassing cell and rooms* in some processes, an automated transfer from steriliser to the degassing cell with no personnel interaction together with good extract and ventilation allows for products to move into the degassing cell without meeting item 2.
