TGD K 2014 – 2.7 – Prevention of falls from windows

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).
