- Persons with impaired hearing
- Persons with intellectual impairment
- Persons with impaired vision
- Persons with physical disabilities
- Unexpected vertical changes of levels (curbs, steps, ruts, gutters, etc.) prevent continuous accessible paths of travel
- Excessive slopes (camber) across the direction of travel on a footpath, which makes control of the wheelchair difficult
- Inadequate provision of space at doorways and within rooms to allow for wheelchair dimensions and turning circles
- Not paying specific attention to steps and handrail design to ensure adequate support and a feeling of confidence and ease when negotiating steps
- Seating does not consist of waiting areas at counters and along lengthy walkways to reduce tiredness
- Access vulnerability associated with doors, including the need to manipulate a handle while using a walking aid and difficulty in moving quickly through swinging doors
- Visual signs are not very clear and accurate. A flashing light unaccompanied by a message can be confusing (e.g. a flashing fire exit sign would be preferable to a flashing red light; it gets the message across much faster)
- Lack of loud speakers with supplementary messages for public premises (e.g. railway stations, bus stations, and airports with visual messages)
- Edges of walls, furniture, and other items are not rounded to prevent physical injury if people walk into it
- Unguarded projections at heights such that someone who cannot see them would be in danger of walking into them
- Obstructions such as cupboards, etc. along corridors or hallways
