BS EN ISO 2867 specifies criteria for access systems — steps, ladders, walkways, platforms, grab rails (handrails), grab handles, guardrails and enclosure entrance and exit openings — as they relate to aiding the operator and servicemen in performing their functions on the machinery.
BS EN ISO 2867 applies to access systems to the operator’s station and to service points on earth-moving machinery as defined in Iso 6165 while the machinery is parked in accordance with manufacturer’s instructions.
4 General criteria
4.1 An alternative exit is required if the operator’s platform is >3 m above ground level, and should preferably be provided if > 2 m above ground level.
4.2 The probability of a user being inadvertently restrained by protruding devices such as controls, steps or handles catching or holding body appendages or wearing apparel shall he minimized.
4.3 Protrusions that could trip the user or increase the severity of injury in case of a fall shall be minimized.
4.4 The probability of user contact with potential hazards such as extreme differences in heat or cold, electrical hazards, moving parts and sharp corners shall be minimized.
4.5 Access systems shall accommodate the 5th percentile through the 95th percentile operator dimensions as defined in ISO 3411.
4.6 Correct use of the access system shall be selfevident without special training.
4.7 Proper placement of components shall permit and encourage a person to use three-point support while ascending, descending or moving about the access system when more than 1 rn above the ground.
4.8 Primary access system devices may be portable for convenient storage on the machine hut shall be capable of being positively secured when in use or in the stored position.
4.9 An alternative exit and travel route shall be provided and shall be clearly indicated if not obvious.
7 Ladders
7.1 Ladder steps shall meet the criteria specified in clause 6.
7.2 Ladders which extend more than 5 m vertically above ground level shall be equipped with a ladder fall-limiting device, preferably of the passive type. Such a device shall not require continual manipulation for the user to ascend or descend the ladder.
7.2.1 The lower end of a vertical ladder cage or other similar device, if used, shall be a maximum of 3 m above ground or platform level.
7.2.2 The internal surface of a ladder cage on a vertical ladder shall not extend more than 700 mm from the steps nor shall its internal width be more than 700 mm.
7.3 A rest platform shall be provided at least every 15 m of vertical climb, and preferably at least every 10 m of vertical climb.BS EN ISO 2867 pdf download.
