  "text": "Machinery intended for underground work must meet all the essential health and safety requirements described in this section (see point 4 of the General Principles at the start of this Annex).\n5.1.\nRISKS DUE TO LACK OF STABILITY\nPowered roof supports must be designed and constructed in such a way as to maintain a given direction when moving and not slip before and while they come under load and after the load has been removed. They must be equipped with anchorages for the top plates of the individual hydraulic props.\n5.2.\nMOVEMENT\nPowered roof supports must allow for unhindered movement of persons.\n5.3.\nCONTROL DEVICES\nThe accelerator and brake controls for movement of machinery running on rails must be hand-operated. However, enabling devices may be foot-operated.\nThe control devices of powered roof supports must be designed and positioned in such a way that, during displacement operations, operators are sheltered by a support in place. The control devices must be protected against any accidental release.\n5.4.\nSTOPPING\nSelf-propelled machinery running on rails for use in underground work must be equipped with an enabling device acting on the circuit controlling the movement of the machinery such that movement is stopped if the driver is no longer in control of the movement.\n5.5.\nFIRE\nThe second indent of section 3.5.2 of this Annex is mandatory in respect of machinery which comprises highly flammable parts.\nThe braking system of machinery intended for use in underground workings must be designed and constructed in such a way that it does not produce sparks or cause fires.\nMachinery with internal combustion engines for use in underground workings must be fitted only with engines using fuel with a low vaporising pressure and which exclude any spark of electrical origin.\n5.6.\nEXHAUST EMISSIONS\nExhaust emissions from internal combustion engines must not be discharged upwards.",
