2.4 Guarding should be provided for any window, the sill of which is more than 1400 mm above external ground level and is less than 800 mm in height above internal floor level (see Diagram 7). Where a window is capable of being opened, special care must be taken to ensure that the guarding must remain in place and effective at all times.

2.5 Guarding should be designed and built in such a way that it does not present unacceptable risks of accidents in service. Where guarding contains glazing, it should be in accordance with the recommendations of BS 6262 – 4: 2005 Glazing for Buildings – Part 4: Code of practice for safety related to human impact (see Diagram 8).

1.1.2 In this sub-section – “flight” means the part of a stairway or ramp between landings; “going” means the horizontal distance between the nosing of a tread and the nosing of the tread or landing next above it; “pitch” means the angle between the pitch line and the horizontal; “rise” means the vertical distance between the top of a tread and the top of the tread, landing or ramp next above or below it; “stairs” means a succession of steps and landings that make it possible to pass on foot to other levels; “tapered step” means a step, the nosing of which is not parallel to the nosing of the step or landing next above it; “tread” means the upper surface of a step.

2.6 In buildings which are likely to be used by children under five years old, guarding should be so constructed that a 100 mm diameter sphere cannot pass through any openings in the guarding. Guarding should not be readily climbable and should be designed in such a way as to discourage young children from climbing it. Features in the guarding that might provide a foothold should be avoided e.g. horizontal rails etc.

2.7 In dwellings where a window has an opening section through which a person may fall, (having particular regard to children under five years old), and is more than 1400 mm above external ground level, suitable safety restrictors should be provided (see Diagram 9). Safety restrictors should restrain the window sufficiently to prevent such falls. Restrictors can be either an integral part of the window operating gear or separate items of hardware which can be fitted to a window at the time of manufacture or at installation. Restrictors should operate so that they limit the initial movement of an opening section to not more than 100 mm. Note: Lockable handles or restrictors, which can only be released by removable keys or other tools, should not be fitted to window opening sections required for escape purposes (see TGD B Fire Safety).
