The Machinery Directive has a number of requirements for applying an Emergency Stop Button, which is what I think you are referring to. This device is a latching red "mushroom" or "palm" style button that removes power to equipment or appropriate actuators. It will also have a yellow background. This requirement is referenced in EN 61010-1:1993 under clause 6.12.2.3 and is pertinent to equipment with moving parts. The criteria for making a decision for fitting an Emergency Stop Button will be based upon your Hazard Analysis and Risk Assessment that is required for equipment under the Machinery Directive. A good standard to follow is EN 1050:1996 Safety of machinery - Principles for risk assessment. In essence if there is any risk of injury to an operator or maintenance technician, a person excluded from the scope of EN 61010-1, from equipment an Emergency Stop Button, or Buttons, should be fitted. Interestingly enough, as this is a transport device it implies that linking the E-Stop to up-stream and down-stream equipment may be required.
