This document applies to outboard ladders for inland navigation vessels. Outboard ladders are used on inland navigation vessels having great side heights to facilitate safe climbing into ship's boats, safe disembarking or safe crossing over onto vessels in the case of significantly different boarding heights. This document specifies safety requirements on design, dimensions and strength and test conditions for outboard ladders. Outboard ladders are intended for that range where removable boarding stairs according to EN 1502 are not sufficient in length. This range starts at a boarding height of approximately at 2,80 m above the light water-line. Boarding ladders are not intended for use by passengers.

This document is applicable to stanchions and holders of tiltable and detachable railings (railing type CT and CD according to EN 711 in work areas) for inland navigation vessels. These railings are situated in the side deck areas, where a permanently fitted railing can be an obstacle for loading/discharging operations. The stanchions are designed for use with handrails and intermediate guardrails made of wire ropes. Dimensions marked with a ● are safety dimensions and correspond to the stipulations in EN 711.

This document applies to boarding stairs for inland navigation vessels. Boarding stairs are used on inland navigation vessels for a safe transition into ship's boats, safe disembarking to the shore or a safe crossing over onto vessels with lower decks. This document specifies safety requirements on the design, dimensions and strength and test methods. Boarding stairs are designed for vessels having a boarding height greater than 1,5 m above the light water-line. They can be used up to a height of around 3,0 m above the light water-line. Boarding stairs are not intended for use by passengers.
