Zhoda s kódom: Etylénoxid (ETO)
A Comprehensive Guide for Sterilization & Fumigation Facilities
1. Receiving and Unloading Procedures
Compliance with subsection 14.2 is mandatory for both full and empty ETO containers.
Safety Checkpoints
- Vehicle engines must be OFF, brakes set, and wheels chocked.
- No smoking or open flames within 25 ft (7.62 m).
- Containers must be kept UPRIGHT at all times.
Handling Prohibitions
- NO Stacking: Containers must never be stacked or rolled.
- Forklift Safety: Do not lift drums by placing forks under chime rings.
2. Storage Standards
Indoor Areas
- Classified for ignition source control (Class I, Div 2).
- Spot heating limit: 125°F (51.7°C).
Outdoor Areas
- 25% of perimeter must be open to atmosphere.
- Clear of dry vegetation for 15 ft (4.6 m).
- Provide protection from vehicle damage.
3. Piping Systems & Gas Dispensing
All metallic piping must comply with ASME B31.3 (Process Piping) and have a minimum melting point of 1500°F (815.6°C).
Ventilation Rate
Mechanical ventilation must operate continuously at no less than 1 scf/min•ft² of floor area.
Shutoff Valves
Each system requires two remotely operated shutoff valves. The first must be within 5 ft (1.5 m) of the container.
4. Disposal and Emission Control
Compliance with Section 14.9 ensures environmental safety and effective ETO neutralization.
Wet Scrubbers
Musí byť navrhnutý tak, aby riešenie nemohlo vstúpiť do procesných liniek. Čistý kvapalný ETO sa nikdy nesmie privádzať priamo do práčok plynu.
Katalytické konvertory
Musí zahŕňať automatické vypnutie, ak teplota prekročí limity dodávateľa katalyzátora.
5. Stavebníctvo & Požiarna bezpečnosť
- Odvzdušnenie výbuchu: Konštrukcie musia mať nehorľavú konštrukciu a kontrolu výbuchu podľa oddielu 6.10.
- Potláčanie požiaru: Skladovacie priestory ETO musia byť chránené a Záplavový systém v súlade s NFPA 16.
- Lepenie: Všetky potrubia musia byť spojené s uzemnením na kontrolu statickej elektriny.
