Abstract

This invention relates to novel systems (10) for testing guards closures or barriers used on hazardous machinery for personnel protection. The guards are tested separately or in conjunction with safety devices which may include interlock (12), locking mechanisms (L) and latching devices (S). The testing process proceeds without having to shut down the machine on which the guarding system is mounted. Testers are incorporated in the process for establishing the integrity of the safety devices and for executing self-testing.
