Hi Folks, The EC Machinery Directive 1.2.2. Control devices states "Machinery must be fitted with indicators as required for safe operation. The operator must be able to read them from the control position. >From each control position, the operator must be able to ensure that no-one is >in the danger zones, or the control system must be designed and constructed in >such a way that starting is prevented while someone is in the danger zone. If neither of these possibilities is applicable, before the machinery starts, an acoustic and/or visual warning signal must be given. The exposed persons must have time to leave the danger zone or prevent the machinery starting up." EN 60204-1 Safety of Machinery Standard does not identify specific requirements for a startup warning however it does provide the generic requirements for indication in 10.3.3 Flashing lights and displays. My question is does anyone know of any similar requirements for visual and/or audible machine start warnings like last paragraph in MD 1.2.2 that are required by OSHA or other USA requirements? I've not found anything like this in NFPA 79 or any OSHA regulations. I suspect it's there somewhere but I've not found it yet. thanks David P.
