What fall height can fall protection mats protect against?

The fall height that safety mats can protect against depends on several factors, including the thickness, material, and design of the mat, as well as the standards and tests they are certified to meet. Safety mats are typically tested according to the European standard DIN EN 1177, which defines the "critical fall height" of a safety surface. The critical fall height is the maximum height from which a fall onto the mat can occur without posing a serious risk of injury.

Typical Fall Heights and Corresponding Mat Thicknesses

Safety mats are available in various thicknesses, each suited to different fall heights:

  • Fall height up to 100 cm
    Mat thickness: approx. 20–30 mm
    Application: Areas with low fall risk, such as under low play equipment or in fitness zones.

  • Fall height up to 150 cm
    Mat thickness: approx. 40 mm
    Application: Playgrounds with moderately tall climbing equipment, balance beams, or slides.

  • Fall height up to 200 cm
    Mat thickness: approx. 50 mm
    Application: Beneath medium-height climbing equipment or swings.

  • Fall height up to 300 cm
    Mat thickness: approx. 70–100 mm
    Application: Areas with tall climbing towers, net structures, or climbing walls.

Additional Factors Influencing Fall Height

  • Material: Most safety mats are made of recycled rubber granules, which absorb shocks and efficiently distribute impact energy. Mats with higher elasticity can handle greater fall heights.
  • Subsurface: The shock absorption of a mat also depends on the surface it is installed on. A firm, stable subsurface maximizes protection.
  • Mat condition: Old, worn, or damaged mats may lose their shock-absorbing properties and should be regularly inspected and maintained.

Certification and Testing

Safety mats are tested in laboratories under controlled conditions. A "HIC value" (Head Injury Criterion) is determined, describing the likelihood of a head injury upon impact. A mat is considered safe if it maintains the critical fall height under a HIC value of 1000.

Practical Application and Selection

Safety mats should always be selected based on the maximum fall height of the equipment or risk zone. Playground operators and planners are required to meet the requirements of DIN EN 1176 (Safety Requirements for Playground Equipment) to ensure user safety. For private or commercial use, consulting with the manufacturer may also be beneficial to ensure the right mat is chosen.

Summary

Safety mats can protect against fall heights of up to 300 cm, with the exact height depending on the mat's thickness, material, and certification. Suitable mats are available for various applications, offering a safe and durable solution.
