What are the fire safety standards for stone and concrete outdoor sofas?

When selecting stone or concrete outdoor sofas, fire safety is a crucial consideration, especially in public spaces or areas prone to wildfires. These materials are inherently non-combustible, but additional standards may apply depending on regional regulations.

Key Fire Safety Standards:

1. Material Flammability: Stone and concrete are naturally fire-resistant, but coatings or cushions must meet flammability standards like ASTM E84 (Surface Burning Characteristics) or CAL 117 (for upholstery).

2. Construction Compliance: Ensure frames or attached components (e.g., metal supports) comply with local fire codes, such as the International Fire Code (IFC).

3. Wildfire Zones: In high-risk areas, materials may need to pass tests like NFPA 701 (flame resistance for textiles) if used with fabric elements.

Best Practices:

- Opt for untreated natural stone or concrete to minimize fire risks.

- Avoid flammable adhesives or finishes.

- Verify certifications (e.g., UL Listing) for added safety.

Always consult local authorities or a fire safety expert to ensure full compliance with regional requirements.
