Children's play structures must be constructed of noncombustible materials.

The assertion that children's play structures must be constructed of noncombustible materials is rooted in safety standards and fire protection measures. Noncombustible materials are those that do not ignite, burn, or emit toxic fumes when exposed to fire.

In the context of children's play structures, using noncombustible materials helps reduce the risk of fire hazards, ensuring the safety of children during play. These materials contribute to overall safety in public and high-traffic areas where children typically play, as they are less likely to catch fire and can slow down the spread of flames in case of an emergency.

Furthermore, many local building codes and safety regulations emphasize the importance of using fire-resistant materials in public recreational equipment to enhance safety and minimize injury risks. Thus, the requirement for children's play structures to be made of noncombustible materials aligns with these safety considerations and building codes intended to protect children's safety in outdoor environments.
