BS 5395-1:2010

• 91.060.30 Ceilings. Floors. Stairs

This part of BS 5395 gives recommendations for the design of stairs with straight flights, including landings and winders for all types of building and industrial walkways.

NOTE 1 External walkways are covered in BS 8300.

It does not apply to steps or stairs which are not connected to a building, for example, those which are part of the surrounding landscape or which provide entry to a property. Whilst information within this standard is relevant to external stairs, a range of additional issues such as durability, performance in variable environmental conditions and the inconsistency of natural lighting can mean that application of this standard alone does not address issues of safety and convenience in external situations.

NOTE 2 BS 8300 addresses these issues in more detail.

This standard does not cover spiral or helical stairs, which are addressed within BS 5395‑2. Industrial stairs are covered in BS 4592‑0.

The standard does not apply to ramps, whether stepped or not, nor to ladders nor to steps within swimming pools.

This standard does not cover limited-use stairs e.g. stairs to be used in loft or basement conversions, which will be addressed within BS 5395‑4²⁾.
