Engineering Guidelines for ETO Sterilization Areas

Designing a facility for Ethylene Oxide (РАССТАНОВКА) sterilization requires rigorous adherence to ventilation and exhaust standards to protect personnel and ensure environmental safety. The primary objective is to maintain a отрицательный воздушный баланс and ensure that all gas residues are captured and exhausted through dedicated, non-recirculating systems.

1. Ventilation & Exhaust Standards

Negative Air Balance The equipment room must maintain a constant negative pressure relative to adjacent areas. All air must be exhausted to the outside via a dedicated “ETO Equipment Room Exhaust” system.

Discharge Safety The exhaust discharge point must be located at least 25 feet (7620 мм) away from any building intake, operable window, or personnel pathway.

Cylinder Change Safety A dedicated exhaust hood must be positioned no more than 1 foot (305 мм) above or behind the cylinder change point to capture any trace leakage.

2. Technical Specifications for Dedicated Systems

System Component	Design Requirement	Safety Objective
Aeration Units	Non-recirculating dedicated exhaust.	Eliminate ETO off-gassing from products.
Relief Valve	Piped directly to a high-altitude outdoor point.	Ensure high-pressure emergency release bypasses intakes.
Sterilizer Door	Hood or canopy closed on each end over the door.	Capture ETO “burp” when the door is opened post-cycle.
Supply Lines	Gas line hand valves at cylinder connection.	Minimize leakage during replenishment cycles.

⚠️

Mandatory Alarm System: An audible and visual alarm must be installed to alert operating personnel immediately if air flow drops below the designed Cubic Feet per Minute (CFM). Never operate the sterilizer if the exhaust system is compromised.
