Interlocking Guard vs Guard Locking | ISO 14119 Explained

This video outline the TS EN ISO 14119:2014 standard, which establishes international protocols for the safety of machinery through the use of interlocking devices associated with guards . This technical standard provides comprehensive principles for the design and selection of these systems, categorizing them into four distinct types based on their actuation methods and coding levels. Key objectives include preventing hazardous machine operations when guards are open and implementing measures to minimize defeat possibilities by users. The video details requirements for mechanical installation , such as the robust fastening of switches and actuators, while also addressing guard locking mechanisms for both personnel and process protection. Furthermore, it serves as a critical guide for ensuring compliance with the essential health and safety requirements of the EU Machinery Directive .
