Where loads are being carried regularly, stairs should be used rather than ladders Number of people The number of people governs the size and the loading see 8. Where two or more materials are used, they should be compatible, e.
The maximum number of risers in a single flight should be 16, for straight stairs, or 22, for helical and spiral stairs. Landings at the head of a stair should be designed so that it is not possible to step from a platform or walkway onto the stair without a change in direction. Typical industrial stairs are shown in Figure 2.
The relationship between rise and going for a stair should not change along the walking line, subject to the same tolerances. The maximum permissible deviation for any size should not exceed the appropriate value given in Table 2 of BS For further guidance see Consistency of rise and going are of prime importance for user confidence and safety.
Treads on open riser stairs should overlap not less than 16 mm and have a nosing depth in the range 25 mm to 50 mm to aid visibility. The length of a landing see Figure 1 should be not less than the clear width of the stair or mm, whichever is the greater. Helical and spiral stairs should have handrails as described in BS Handrails should be provided wherever the total height of the pitch line above the adjacent construction exceeds mm.
Fixed ladders should have equal rises in successive flights wherever practicable. Access points to the head of ladders from platforms and walkways should be protected by self-closing gates see No part of the ladder should project onto the passageway.
Except on chimneys, the height of a ladder should not exceed 6 m without an intermediate landing, preferably breaking the line of the ladder.
If a user could fall 2 m or more, or come into contact with dangerous equipment, the ladders should be fitted with safety equipment see 6. Typical fixed ladders are shown in Figure 3. The top rung of a ladder should be replaced at the same level as the floor or platform to which access is provided by either: a a flat supported plate [see Figure 3 d ]; or b industrial type metal flooring complying with BS ; or c additional rungs in a horizontal plane [see Figure 3 e ].
The minimum rise should be mm and the maximum rise should be mm. Handrails, which may be an extension of the string, should extend upwards at the same angle as the ladder to a height of not less than mm above the upper platform and be securely fastened at their extremities.
Such an extension should not encroach on the clear width of the platform passageway. At platform level the strings should widen out and be bent over and connected to the handrail [see Figure 3]. Above platform level the clear width between strings should be not less than mm and not more than mm. Landings should not be less than mm square and should have toe plates and handrails around all open sides see Clauses 9 and Clause Cages should be constructed of components robust enough to minimize flexing.
The hoops on any safety cage should be placed at equal intervals not more than mm apart. The top hoop should be in line with the top guard rail on the platform. The bottom hoop should be at a height of mm above ground.
The sizes of hoops should be as shown in Figure 3 c. Where maximum enclosure is desirable because of an elevated position or other hazard, one half of the hoop structure may be extended down to near floor level.
In particularly hazardous and exposed situations, mesh panels may be used to cover the ladder cage [see Figure 3 a ]. Typical details of companion way ladders are shown in Figure 4.
The front edge of the first step down from platform level should be a minimum of mm from any vertical wall or other obstruction. The top surface of the top tread should be positioned at platform level and there should be no gap between the tread and the platform see Figure 4. A single handrail should always be provided on both sides of a companion way ladder; the distance between rails, from centre to centre, should be not less than mm.
Stanchions supporting handrails should be positioned at right angles to strings. At the top of a companion way ladder, handrails should widen out to a minimum width of mm see Figure 4. The minimum headroom above the top surface of a platform or walkway should be mm. NOTE It is advisable to fix plates or labels to installations stating that they have been designed following the recommendations of this code.

Part 1 of EN ISO gives advice about the correct choice of access means when the necessary access to the machine is not possible directly from the ground level or from a floor.
This part of EN ISO applies to all machinery stationary and mobile where fixed means of access are necessary. NOTE 2 For mobile machinery. Safety of machinery — Permanents means of access to machinery — Part 3: For the purposes of this document.
In particular. Safety of machinery — Permanents means of access to machinery — Part 1: Where there are moving objects.
NOTE 2 Where no local regulation or standards exist, this part of ISO can be used for means of access which are outside the scope of the standard.
The ISO series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary. It is not applicable to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels. Check out our FAQs.
