Compliant storage and rental solutions for Propylene (C3H6O). EPA, OSHA, and NFPA guidance for containment, segregation, and fire protection — with rental buildings matched to this material.

Almost two-thirds of propylene is used to make polypropylene, 2 a plastic resin used to make apparel, plastic squeeze bottles, outdoor furniture and many other products. Propylene oxide is used to make furniture, automotive parts, boats and recreational vehicles, appliances, solvents and resins.
Dry Chemical fire suppression is recommended for Propylene
Guidance: Dry Chemical fire suppression is generally recommended for Propylene (C3H6O). *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: Use an extinguishing agent suitable for the surrounding fire
Always confirm extinguishing agents against the manufacturer SDS and your authority having jurisdiction before specifying a rental building fire-suppression package.
Compliant storage and rental solutions for Propylene should account for its listed hazards (FLAMMABLE GASES - Category 1 GASES UNDER PRESSURE - Liquefied gas), climate control needs (Ambient), and segregation requirements. Solvents
