On The Playing Areas, A Biological-Mechanical Deep Cleaning Of Sand (Play Sand, Fall Protection Sand) And Gravel Areas Must Be Carried Out Annually With Automatic Electronic Documentation. The Cleaning Depth Must Be A Constant 40 Cm With Sufficient Dumping Depth To Ensure Oxygen Supply To The Anaerobic Microflora. At The Same Time, The Compacted Sand/Gravel Is Loosened To Restore Fall Protection. It Must Also Be Ensured That Organic And Inorganic Contamination (E.G. Cigarette Butts, Broken Glass, Drug Syringes, Etc.) With A Particle Size Of Eight Millimeters Or More Is Removed. In Particular, Animal Excrement Must Be Filtered Out. The Automatic Electronic Documentation Is Carried Out By A Recording And Measuring Element On The Cleaning Machine, Which Electronically Determines The Cleaned Area Size And Average Cleaning Depth. As A Result, The Ag Receives An Automated Protocol That Documents The Cleaning Depth And Area Size, Which Fulfills The Documentation Obligation In Accordance With Din En 1176. This Data Can Be Used To Determine A Sufficient Amount Of Fall Protection Or To Plan Follow-Up Measures.
