The control system must be designed and arranged so that the machine can be stopped by being pressed simply and lightly by any part of the worker's body should his hands be caught in the moving rollers.Apart from the braking system, the stop mechanism referred to in the previous paragraph must also include a system enabling the simultaneous reversing of the movement of the rollers before their final stop....Article 157The reels of wire-drawing machines must be equipped with a device, which can be activated directly by the worker, enabling the machines to be stopped immediately in case of necessity....Article 165Platen printing presses and similar machines which are not provided with automatic feeders must be equipped with a device enabling the machine to be stopped automatically by a single blow of the worker's hand, should he be in danger between the fixed bed and the moving plate, or they must be equipped with another appropriate safety device of proven effectiveness....Article 209A rapid halting system must be provided at each loading and unloading position on vertical hoists with moving surfaces....Article 220Inclined surfaces must be equipped with a safety device which can bring about the rapid halting of the wagons or trains should the traction systems break or slacken, if that proves to be necessary because of the length and gradient of the run, the operating speed or other particular features of the installation, and in any event if they are used, even sporadically, for the transport of persons.If it is not possible, for technical reasons relating to the particular features of the installation or its operation, to use the device referred to in paragraph 1, the systems of traction and wagon-coupling must present a safety coefficient of at least eight: in such a situation, the use of inclined surfaces for the transport of persons is prohibited.In any event, the traction and coupling systems, like the safety devices, must be checked monthly.....Article 374...Plant, machinery, equipment, tools and instruments, including protection equipment, must have the qualities of resistance and suitability demanded by the requirements of work safety and must be maintained in a good state of repair and efficiency. When maintenance manuals are supplied with the equipment referred to in paragraph 2, they must be kept up to date.’
