To ensure safety in machinery, standards like ISO 12100 recommend using fasteners not commonly removable without special tools. Safety guards must be strategically placed, considering safe distances to prevent bypassing by reaching over, around, or through. ISO 13857 helps calculate these distances, taking into account the height of the hazard and the guard's placement. Both hard guards and presence-sensing devices like light curtains need correct installation distances to be effective. Schmersal offers solutions for integrating these safety measures, emphasizing the importance of appropriate guard heights, distances, and the use of tamper-proof fasteners for fixed guards to maintain a safe working environment.
