Approved Document K includes advice on protection from falling, collision and impact. 

Protection from falling involves the fitting of safety measures on staircases, ramps and ladders, as well as advice about the positioning of balusters, vehicle barriers and windows to avoid injury. 

Guidance for avoiding collision and impact is detailed in the positioning of doors and windows within a property, ensuring that no injuries occur due to occupants colliding with open windows, skylights, ducts etc., that large panes of glass are marked to avoid accidental impact with them, and that doors and windows are not positioned in a way that could trap someone. 

This document is particularly relevant to those who are building a loft conversion and contains guidance in relation to building a staircase for access to the loft.
