What makes an electrical machine isolator safe?

Where do I need to locate my emergency stops? This podcast is going to cover, not just where to locate your emergency stops around your machines or on the machine itself, but what else you need to consider. This is will help make the decision process much easier, and you will at least have some clarity of what to think about, when you need to think about installing emergency stops on or around machines.  VALUABLE RESOURCES BS EN ISO 12100:2010Safety of machinery.

Description Risk assessment for safety related parts of control systems, and how to approach those first decisions on what to do. KEY TAKEAWAYS This is an extra step, and builds on the information of the risk assessment, that you carried out at the beginning of the machine design.  This is not just for controls engineers, but for anyone who is involved with machinery, now has the ability and power to make a valuable input in the overall design of the safety related parts of the control system.    VALUABLE RESOURCESEpisdoe 7 - How to structure a machinery risk assessment https://shows.acast.com/645951b1f6507e00111e7501/64b06f03f1f89f00119699f1Episode 12 - How to deal with hazards on machineshttps://shows.acast.com/645951b1f6507e00111e7501/64b07078f1f89f001196d2d0BS EN ISO 12100:2010Safety of machinery.

Description   The safety related part of the control system, is the brains, it's the intelligence, it's the part of your machine that will decide, if something is safe for you to interact with or not.  BEST MOMENTS ·      1 - Can they operate in the environment that you are using it? ·      2 - A fault in the hardware doesn’t create a hazardous situation. ·      3 - Errors in the control system logic do not lead to hazardous situations. ·      4 - Reasonably foreseeable human error during operation does not lead to hazardous situations.   VALUABLE RESOURCES BS EN ISO 12100:2010Safety of machinery.

Description    Once you've got hold of your maintenance manual, and the type of information you should expect to see contained within it  I'm going to cover the first 8 area's that you might expect to see in the manual, not all of it will apply to your machine, but it will give you a good indication of what to expect, and it is up to you to either provide it, if you are a manufacturer or request it, if you are the buyer of the machine. This episode has been made to serve both.   KEY TAKEAWAYS ·       As a manufacturer you must state how the machine must be used, it sounds obvious, but you must state it, and be precise about the purpose of the machine.  ·       Once the operators are trained in the safe use of the machine, you can then think about what if any residual risks are around the machine.     VALUABLE RESOURCES BS EN ISO 12100:2010Safety of machinery.
