What are the fire safety regulations for WPC materials used in public outdoor tree boxes?

When using Wood-Plastic Composite (WPC) materials in public outdoor tree boxes, adhering to fire safety regulations is crucial to ensure public safety and compliance with local building codes. WPC materials must meet specific fire resistance standards, such as ASTM E84 or EN 13501-1, which evaluate flame spread and smoke development.

For outdoor applications, WPC should be classified as non-combustible or have a low flame spread rating to minimize fire hazards. Additionally, local regulations may require treatments with fire retardants or the use of inherently fire-resistant WPC formulations. Proper installation and maintenance, including avoiding proximity to ignition sources, further enhance safety.

Always consult local authorities and fire safety experts to ensure your WPC tree boxes meet all applicable regulations, protecting both property and public well-being.
