Oberentfelden municipal administration, Switzerland. The Entfelden district school has around 1400 children and young people. All primary and secondary school classes are taught in the school buildings "Eichhölzli", "Roggehuse" and "Feld" in Unterentfelden. The artificial stone stairs were slippery and were coated with GriP to prevent slipping.
Artificial stone stairs and stone steps are particularly slippery and therefore dangerous to fall on. After a fall on stairs, a quick non-slip solution is often sought that makes the slippery surface immediately slip-proof. Anti-slip strips from the DIY store are bought and glued onto the stairs. Although anti-slip strips make the stairs less slippery in places, they are not a permanent or safe anti-slip solution. The anti-slip strips or anti-slip pad often stick with difficulty and dirt always collects at the edges. Eventually they detach from the surface and the anti-slip strips themselves become a danger of slipping and tripping.
