The flexible hoses for hydraulic fluids under a pressure of more than 50 bar and for pneumatic fluids of more than 10 bar shall be secured to the machine by additional fastenings (for example chains) limiting the whiplash.On machines equipped with guards, this requirement does not apply to flexible hoses situated inside the guards.
However, additional fastenings for flexible hoses for blowing fluids are also required inside the machine,except if the machine is safeguarded by interlocking guards with guard locking and the pressure in the pneumatic hoses is reduced to under 10 bar before the guard lock can be released. The PL for this safety function shall be C.
To prevent burns through unintentional contact with hot machine parts, products or conditioning fluids, fixed guards or insulation shall be provided at accessible parts outside of the guarded area where the maximum operating temperature can exceed the limit values given in EN ISO 13732-1:2008. The same requirements apply for very cold parts (EN ISO 13732-3:2008).
Before another cycle can be initiated, it shall be necessary to reset those additional safety devices, to close the guards or reset each ESPE preventing access to the protected area that has been interrupted and then actuate an enabling device to confirm that the danger area has been vacated.’ There shall be a clear view of the danger area from the position where the safety devices are reset and also the enabling device is actuated using, if necessary, aids to vision. It shall not be possible to actuate these devices from the danger area. For acknowledgement systems Annex A applies.
Where these additional devices are fitted in conjunction with power operated movable guards, the closing movement of the guard shall be actuated by means of a hold-to-run control device which is positioned to ensure a clear vision of the danger area. The required performance level for the safety-related parts of the control circuit associated with the hold-to-run control device shall be PLra. AS 4024.3201 pdf free download.
