Guidance: Dry Chemical fire suppression is generally recommended for Ethylene Oxide (C2H4O). *Please consult your raw material manufacturer's safety data sheet (SDS) and your local authority having jurisdiction to verify the most adequate fire suppression extinguisher for your specific storage or use.
Additional extinguishing notes: alcohol foam, carbon dioxide, dry chemical or water spray, fog, or foam
Always confirm extinguishing agents against the manufacturer SDS and your authority having jurisdiction before specifying a rental building fire-suppression package.
Storage & segregation guidance
Compliant storage and rental solutions for Ethylene Oxide should account for its listed hazards (FLAMMABLE GASES - Category 1), climate control needs (Avoid temperates above 38 ºC and do not exceed temperatures of 52 ºC), and segregation requirements. Ethylene Oxide is not compatible with AMMONIA; METALS (such as POTASSIUM, SILVER and MERCURY); ALCOHOLS; MERCAPTANS; CYANIDES; AMINES; and HALOGENATED HYDROCARBONS (such as METHYLENE CHLORIDE and TRICHLOROETHYLENE).
Review NFPA 30 flammable liquid storage requirements and Fire-rated chemical storage rental when designing fire rating, containment, and building selection.
