Critical fall height (CFH) is a vital safety standard for playground surfaces that was established by the American Society for Testing and Materials (ASTM). In essence, CFH is a measure of how well a surface absorbs impact, providing insight into how well the surface can protect against injury. It’s the height below which a life-threatening head injury should not occur, measured as the vertical distance between the playground surface and the highest play area. It’s important to understand playground surfaces’ CFH so you can take steps to reduce the risk of injuries.
