Risks in cleaning, servicing and maintaining a structure can be reduced by designing so that maintenance can be done at ground level or safely from the structure, for example air-conditioning and lift plant at ground level, inward-opening windows, and window-cleaning bays or gangways in the frame; avoiding dirt traps; designing and positioning permanent anchorage and hoisting points where maintenance at height is needed; safe access such as stairs or fixed ladders with space to work; eliminating or minimising entry into confined spaces; and using durable materials that need no re-coating or treatment.
