When selecting outdoor benches for public spaces, safety standards are paramount, particularly regarding sharp edges. Reputable manufacturers adhere to strict guidelines, most notably the ANSI/BIFMA outdoor furniture standards and the CPSC's playground equipment guidelines, which extend to adjacent seating.
The primary rule is the elimination of hazardous sharp edges. All corners and edges must be radiused, typically to a minimum of 1/8 inch (3mm) radius, creating a smooth, rounded profile. This applies to the entire bench structure: seat planks, armrests, frame corners, and decorative elements. Materials must be durable and non-splintering, with finishes that resist corrosion and peeling to prevent the creation of sharp points over time.
For benches in parks, playgrounds, or school grounds, compliance with standards like ANSI/BPI-2017 is critical. These require not only rounded edges but also robust construction to prevent pinch points, secure fasteners (often recessed or covered), and the use of non-toxic materials. Regular maintenance inspections are essential to check for wear, corrosion, or damage that could create new sharp hazards. Ultimately, a safe outdoor bench seamlessly blends durability, comfort, and proactive hazard mitigation through intelligent, rounded design.
