Not apply to the following areas or parts of a building where there is a relatively high risk to persons with a disability (c)Areas used for storage of raw materials, produce or for bulk storage where: (i) the stored materials are hazardous; or (ii) the public is not permitted to enter, such as waste containment area, chemical store, or the like. (d)Mezzanine floors used only for storage, plant and equipment installations or the like. (e)Raised platforms used primarily for purposes of security or safety management, including, but not limited to, guard towers or fixed lifeguard stands. (f)Swimming pools (The water containing pools only). (g)Any path of travel providing access only to an exempted area.

6 DESIGN GUIDELINES FOR THE ELDERY AND ELDERLY WITH FRAILTY
Design Considerations Elderly persons May be unstable in their gait and unable to recognise changes in level of floor surfaces. May be unable to see clearly and may have problems in accommodating dramatic changes of lighting levels. Would have decreased stamina. May have difficulties in way finding. May fall due to bending, stooping and stretching. May be weak in gripping, and may have difficulties in turning and manipulating taps, switches, door handles and the like. May have difficulties in pushing open heavy doors.
Enhanced Designs Barrier free access without steps Slower speed of escalators Luminous contrast between wall and floor Resting place along long corridor Different colour floors and zonings to improve way finding Double switches and low level cupboards Timber or plastic-coated hand rails Bathroom doors openable on both sides Sound-absorbing materials and non-glare floor finishes
