Ethylene Oxide Sterilization

Advantages of EtO are:

Low temperature
High efficiency – destroys microorganisms including resistant spores
Large sterilizing volume/ chamber capacity
Non corrosive to: plastic, metal and rubber materials
Disadvantages are:

Excessively Long cycle
Safety concerns - carcinogenic to humans
Toxicity issues - toxic residues on surgical instruments and tubing
Not recommended for flexible scope
EtO is flammable
Requires special room conditions, safety equipment and separate ventilation system
Relatively high annual costs for maintenance, servicing and consumables
