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
Verður að vera hannað þannig að lausnin komist ekki inn í vinnslulínur. Hreint fljótandi ETO má aldrei gefa beint inn í gashreinsibúnað.
Hvatabreytar
Verður að innihalda sjálfvirka lokun ef hitastig fer yfir mörk hvatabirgja.
5. Framkvæmdir & Brunavarnir
- Sprengjuloftun: Mannvirki verða að vera með óbrennanlega byggingu og sprengivörn samkvæmt kafla 6.10.
- Brunavarnir: ETO geymslusvæði verða að vera vernduð með a Deluge System í samræmi við NFPA 16.
- Tenging: Allar lagnir verða að vera tengdar við jörð til að stjórna stöðurafmagni.
