Protection from collision with open windows, skylights or ventilators
Windows, skylights and ventilators must be designed so they can be left open without danger of people colliding with them, through positioning projecting parts away from circulation routes or installing guiding features.
It is the view of the Department that the requirements of regulation 60 in Part H will be met if windows, skylights or ventilators can be left open without the danger of people colliding with them. This could be achieved by – (a) installing windows, skylights or ventilators, so that projecting parts are kept away from people moving in or about a building; or (b) installing features which guide people moving in or about a building away from any open window, skylight or ventilator. An appropriate level of safety can be achieved by different standards of provision, depending on the circumstances; for example, in a building to which the public are admitted, the standard of provision may be higher than in a dwelling, to reflect the lesser familiarity and greater number of users. Where access is required only for the purpose of maintenance, greater care can be expected from those gaining access, and it would be reasonable that less demanding provisions could satisfy the requirement.
