BS EN 15955-2-2013 pdf download.Railway applications Track Demountable machines and
associated equipment Part 2: General safety requirements.
If it Is not possible to comply with this requirement and access is only available from one side of the machine then the instruction handbook shall detail the restriction of use; see 8.2.1 (26).
Signs complying with the requirements of 8.3 shall be fixed at each egress point to warn personnel of the dangers from passing traffic.
A device for restricting egress from the side of the demountable machine open to rail traffic shall be provided to prevent people leaving the machine on the side open to traffic by mistake e.g. a door with a latch, a chain and hook. Where possible this shall require the operator to carry out an intentional action to leave the machine.
Where doors are fitted as an addition to the host vehicle they shall:
be maintained in the fully open and closed positions by automatic latches suitable for the foreseen forces. It shall be possible to lift the latches by means of the inside and outside handles;
not project beyond the loading gauge when open;
make opening quickly and easily possible by the design and position of the door handles, but the design should prevent unintentional opening of the door. The door handles shall be easily accessible and ergonomically shaped and safe;
be possible, without difficulty, to open and close from both outside and inside the cab. A lock and a handle shall be arranged on the outside of the doors at a height of 1 250 mm to 1 500 mm above rail level or step level where this is provided to gain access. An additional handle shall be provided at a height of 700 mm to 1100 mm above the cab floor level;
the door opening shall comply with the requirements of EN ISO 2867.
Where doors which are part of the host vehicle do not comply with the clause above, a note shall be made in
the instruction manual; see 8.2.1 (25).
5.2.2 Working places, places for control and maintenance outside of cabs
Where reasonably practical, working places shall be positioned within the machine running gauge, as defined in EN 14033-1:2011, Annex C.
Where it is not reasonably practical to position work places within the running gauge, the manufacturer shall inform the user, in the instruction handbook, of the inherent risks with regard to working places located outside the running gauge; see 8.2.1 (25). In addition, a fixed warning notice according to the requirements of 8.3 shall be displayed adjacent to each such working place.
Except as shown below, access and egress from all working places outside of cabs shall be from both sides of the machine or directly into the area between the rails of the working track.
5.4.2 Minimum dimensions In cabs
Except under the conditions of the following paragraph, the minimum space available to the operator shall be as defined In EN ISO 3411.
For cabs with limited headroom (measured from the seat index point, as specified in EN ISO 5353, to the roof) caused by technical requirements, the minimum space envelope height (dimension R1 according to EN ISO 3411:2007, Figure 4) is permitted to be reduced to 920 mm.
The minimum space and location of the controls at the operators station shall meet the requirements specified in EN ISO 6682.
5.4.3 Cab floors
The floor of cabs shall be constructed In confomance with the requirements of EN ISO 14122-2.
5.4.4 Emergency exit
An alternative opening as emergency exit shall be provided as specified in EN 474-1:2006+A1:2009, 5.3.2.4.
5.4.5 Climatic conditions in cab
Where an enclosed cab is fitted, this sub-clause shall be applicable in all cases.
Cabs shall protect the operator against foreseeable adverse climatic conditions.
Cabs shall be thermally insulated and shall be equipped with an adjustable heating and ventilation system. which, if not already fitted to the host vehicle the system, shall be according to EN 474-1 :2006+A1 :2009.
5.3.2.6,
The doors and windows shall protect against rain, exhaust gases and wind. Where fitted, pipes, cable ducting, and valves shall not compromise this requirement.
5.4.6 Protection from dust
Where practicable, machines with devices that grind rails, transfer ballast or work on the formation shall have the permanent places of work in enclosed cabs. These cabs shall be equipped with devices to prevent the ingress of dust. Where it is not practicable to provide cabs, dust, sparks etc shall be directed away from any possible position where personnel need to be, and personal protective equipment (PPE) identified and stated In the instruction handbook: see 8.2.1, 2).
Where the intended use of the machine causes dust ingress to the cab, the manufacturer shall use particle filters designed to be sufficient to prevent 95 % of dust, as specified below, into the cab: this particle filter shall be tested according to ISO 10263-2.BS EN 15955-2-2013 pdf download.
